How to Search Google Scholar: Operators, Library Links, and Labs
Google Scholar is a free index of scholarly literature, not a peer-reviewed database. Start at scholar.google.com and follow Google Scholar Search Help: put a known title in quotes, use the author: operator, turn on library links such as FindIt@Harvard, and treat the Cite popup as a draft. If you are signed in, Scholar Labs can take a research question instead of a keyword string; Quick Read (25 August 2026) then summarises a paper you can already open. This page is the Scholar workflow. It is not how to find scholarly sources in general, not library databases, and not how to get the PDF.

How to search Google Scholar: quick answer
Put a known title in quotation marks, or combine a topic with author:"family name". Keep results ranked by relevance and narrow recent work with Since Year in the sidebar. When you need the paper, click a library link, a [PDF] or [HTML] link, or All versions. Searching Scholar is free; the full text may still sit behind a subscription. For a multi-part research question, sign in and switch to Scholar Labs instead of stacking more keywords.
Official Search Help operators and the 2026 question modes
Author (official example)
author:"d knuth" or author:"donald e knuth"
Exact title (official example)
"A History of the China Sea"
Recent, still ranked by relevance
Run the search, then click Since 2018 in the left sidebar.
Newest additions first
Click Sort by date in the sidebar. On small screens, open the Year menu under the search button.
Citation alert (official example)
Search "Anti de Sitter space and holography", open Cited by, then click the envelope icon.
Scholar Labs (signed in)
Ask the research question in a sentence. Labs identifies topics, aspects, and relationships, then returns papers with a short note on how each one helps.
Quick Read (signed in, English papers you can open)
On a deep hit, click Quick read for Answers, Approach, and Considerations — then open the PDF before you cite.
What this page is for
Use this URL when the job is operating Scholar: Search Help operators, library links, citation chaining, alerts, the Cite export, Scholar Labs, Quick Read, the PDF Reader, Scholar Metrics, and a profile's Public Access list. How to find scholarly sources is the wider map of catalogs and subject databases. How to use library databases is thesauri and peer-review filters. How to access academic journals is paywalls, interlibrary loan, and repositories. Citation metrics is h-index and journal impact beyond Scholar's own numbers. How to cite AI is how to cite a chatbot; Labs and Quick Read are finding tools, not sources. Keep those jobs off this page.
What Google Scholar actually indexes
Scholar does not publish a live document count, and it does not claim every result is peer-reviewed. The coverage statement on Search Help is the rule:
Google Scholar Search Help, Content Coverage
Google Scholar includes journal and conference papers, theses and dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research.
Google Scholar also includes court opinions and patents.
The same page says coverage is a search of academic papers, not a guarantee that every short item made the index:
Google Scholar Search Help, How complete is your coverage?
Shorter articles, such as book reviews, news sections, editorials, announcements and letters, may or may not be included.
Untitled documents and documents without authors are usually not included.
The inclusion guidelines written for webmasters draw the same line from the other side. Scholar also answers the "which journals?" question by refusing it:
Inclusion guidelines and Search Help on journals
Content such as news or magazine articles, book reviews, and editorials is not appropriate for Google Scholar.
Ahem, we index papers, not journals.
That is why a Scholar hit can be a journal article, a preprint, a dissertation, a court opinion, or a [citation] record Scholar has not found online. Search Help's coverage check is to search a sample of titles in quotes — not to trust a journal-name list. You still have to classify the item. Scholarly vs popular sources is the type map; How to evaluate sources is the CRAAP pass after you leave the result.
Search the way Search Help documents it
Author and title
Scholar's own examples are the ones to copy. Do not put a space after the colon in author:. Quotes keep a multi-part name or a full title together. Donald E. Knuth is a real computer scientist; those strings are Scholar's examples, not invented names. His public profile is Donald E. Knuth.
Google Scholar Search Help, Searching
How do I search by author?
Use the "author:" operator, e.g., author:"d knuth" or author:"donald e knuth".
How do I search by title?
Put the paper's title in quotations: "A History of the China Sea".
If several people share a surname, add a co-author or a topical word. Search Help gives the same advice for following author:s-hawking.
Advanced search
Open the side drawer (the three-line menu) and choose Advanced search. Search Help says that window searches the author, title, and publication fields and can limit by date. Harvard Library restates the same fields and notes that Scholar indexes full text, not only metadata.
Google Scholar Search Help, Where is advanced search?
It's in the side drawer. The advanced search window lets you search in the author, title, and publication fields, as well as limit your search results by date.
Harvard Library, Google Scholar Tips
Like Google, Google Scholar allows searching of metadata terms, but unlike Google, it also indexes full text.
Results are returned in relevance-ranked order, generally favoring entries when search terms appear in document titles and prioritizing documents with larger citation counts.
Phrases, OR, site, and exclusion
Search Help's documented operators are author:, quoted titles, site: on the primary version of a paper, and allintitle: in coverage examples. A space is treated as AND. Harvard Library and MIT Libraries also document quoted phrases, Boolean queries, and fielded search. Official help does not document a * wildcard; do not rely on one.
Operators you can type
- Quoted phrase.
"pediatric hyperalimentation"— Search Help's own example after reading a Wikipedia article on overweight. - OR.
college OR universitykeeps either term. - Exclude. A hyphen before a word drops it:
mercury -planet. - Title words.
allintitle:"google scholar"is the coverage-check query Search Help names. - Site.
site:searches the primary version of each paper, not every copy Scholar clustered.
Google Scholar Search Help, site: and Getting better answers
The "site:" operator currently only searches the primary version of each paper.
E.g., a Wikipedia article for "overweight" might suggest a Scholar search for "pediatric hyperalimentation".
Date: relevance first
Results are normally sorted by relevance. Harvard Library restates the ranking as favoring titles and larger citation counts. Search Help still warns against flipping to date sort as the default:
Google Scholar Search Help, How do I sort by date?
You'll often get better results if you search only recent articles, but still sort them by relevance, not by date. E.g., click "Since 2018" in the left sidebar of the search results page.
Use Sort by date when you want the newest additions, then set an email alert if you will repeat that scan. Alerts go out after Scholar adds papers, which Search Help says usually happens several times a week.
Scholar Labs: ask a research question
Keyword search is still the documented default. Scholar Labs (18 November 2025) is a signed-in mode for a detailed research question. The 3 June 2026 update is the current product description: Labs is available for all logged-in users and supports questions in all languages; the updated ranking launched in English first.
Google Scholar Blog, Scholar Labs (18 November 2025)
It analyzes your question to identify its key topics, aspects and relationships. It then searches for all of them on Scholar, and evaluates the results to identify papers that answer the overall research question.
For each paper, it provides a brief description of how the paper helps answer your question.
Google Scholar Blog, Scholar Labs update (3 June 2026)
Finds results ~10x faster
Scans up to 3x more papers, to find the most helpful results
Allows users to do 10x more searches every day
Scholar Labs is available for all logged in users and supports questions in all languages. The updated version of Labs is available in English starting today, and we hope to roll this out to all other languages shortly.
The June 2026 post says you can ask follow-up questions, and that Labs still includes the familiar Scholar features — Cited by, Related articles, library links, and Cite. Use Labs when the assignment is a question with more than one concept ("how do later papers test Maldacena's AdS/CFT proposal after Witten 1998?"). Use the keyword box when you already have a title, an author, or a reproducible Boolean string you need to report.
Use the keyword box
- A known title in quotes
- An author: search you can write down
- A site: or allintitle: coverage check
- A documented systematic-review string
- You are signed out
Use Scholar Labs
- A multi-part research question
- A methods detail you cannot name yet
- A last-pass "did I miss a paper?" check
- Follow-up questions on the same thread
- You are signed in
Labs still searches Scholar. It does not add a peer-review filter, it does not lift the 1,000-result cap on ordinary search, and it does not make a [citation] row readable. Do not cite "Scholar Labs" in the paper. Open the article it found and cite that. If you used a chatbot instead of Labs, how to cite AI is the citation rule.
Quick Read: Answers, Approach, Considerations
On 25 August 2026 Scholar added Quick Read to Labs and to ordinary search. A Quick read link appears on results that discuss your query in depth. It is a query-focused summary of a paper you can already open — not a new access path.
Google Scholar Blog, Quick Read (25 August 2026)
Click "Quick read" to read a short presentation of the paper focused specifically on your query. You'll see an overview and three sections: Answers, Approach, and Considerations.
The Answers section presents an overview of what the paper says about your query as well as the supporting details for each of the points.
The Approach section describes the methods and techniques from the paper that are relevant to your question.
Finally, the Considerations section lists some caveats to keep in mind as you analyze the results.
Quick Read links appear only for papers that you have access to.
Quick Read is available for logged in users and is currently limited to English articles.
Treat Quick Read the way you treat an abstract: it can tell you whether to open the PDF. It cannot replace the methods section, the tables, or a retracted-article notice on the publisher page. If the link is missing, you are signed out, the article is not English, or Scholar does not think you have access — turn on library links and try again.
Read one result before you cite it
A Scholar row is a cluster, not a finished bibliography entry. Search Help's sample result shows the pieces you actually get: title, abbreviated authors, venue fragment, year, host, snippet, Cited by, Related articles, and All N versions.
What each control is for
- Title. Opens a publisher, repository, or abstract page. Confirm the version of record before you cite.
- [PDF] / [HTML]. A free-to-read copy Scholar found. It may be a preprint, a manuscript, or the published PDF.
- Library link. Official example: FindIt@Harvard, to the right of the result.
- Cited by. Newer papers that reference this one. Use it when the first hits are too basic.
- Related articles. Documents similar to this result, not a second keyword search.
- All versions. Other hosts for the same work, including author sites and repositories.
- Quick read. A query-focused summary, only if you are signed in and can open the paper.
- [citation]. A work other papers cited that Scholar has not found online. Uncheck include citations in the sidebar to hide them.
Google Scholar Search Help on Related articles and [citation] rows
It finds documents similar to the given search result.
These are articles which other scholarly articles have referred to, but which we haven't found online. To exclude them from your search results, uncheck the "include citations" box on the left sidebar.
Search Help's chaining advice is the research move students skip: if the hits are too narrow, read their reference lists; if they are too general, open Cited by. The official illustration for a citation alert is the real 1998 paper Anti de Sitter space and holography — Edward Witten, Advances in Theoretical and Mathematical Physics 2 (1998): 253–291, arXiv:hep-th/9802150 (journal reference on the arXiv record: Adv.Theor.Math.Phys.2:253-291,1998). Search Help's title string is the one to paste; the arXiv page capitalises it as Anti De Sitter Space And Holography.
Google Scholar Search Help, How do I get notified when a particular paper is cited?
Search for the title of your paper, e.g., "Anti de Sitter space and holography"; click on the "Cited by" link at the bottom of the search result; and then click on the envelope icon in the left sidebar of the search results page.
Get the full text: library links and versions
Abstracts are free for most articles. The paper may not be. Search Help's access order is the one to try first:
Google Scholar Search Help, Locating the full text of an article
click a library link, e.g., "FindIt@Harvard", to the right of the search result;
click a link labeled [PDF] to the right of the search result;
click "All versions" under the search result and check out the alternative sources;
click "Related articles" or "Cited by" under the search result to explore similar articles.
Turn on library links (up to five)
On-campus, Scholar can detect subscriptions automatically. Off-campus, set Library links so resolver labels appear beside results. The live Scholar settings page still says to choose up to five libraries. Settings live in a browser cookie; if you clear cookies, set the links again.
- Open Google Scholar and sign in if you want the choice saved across browsers.
- Open the three-line menu, then Settings, then Library links — the path MIT Libraries documents.
- Search your institution. Harvard Library's public steps: type Harvard and select Harvard University — Try Harvard Library, then deselect WorldCat if it appears.
- Check the box for your resolver and click Save.
- Search again and look to the right of a result for the library label.
Google Scholar Settings, Library links
Show library access links for (choose up to five libraries):
Online access to library subscriptions is usually restricted to patrons of that library. You may need to login with your library password, use a campus computer, or configure your browser to use a library proxy.
If no resolver appears, the library has to register its link resolver with Scholar; ask a librarian rather than inventing a bookmarklet. MIT's next step when Scholar has no PDF and no MIT link is to search the catalog, then request the item through interlibrary loan. That is the same path as How to access academic journals.
Off-campus links expire
Search Help describes a second mechanism: if you use Scholar on campus, it can record your subscriptions and keep showing subscribed [PDF] / [HTML] links off-campus. That recording expires after 30 days and is deleted. The settings page labels the control Signed-out off-campus access links and explains it as "Use my on-campus library subscriptions to enable off-campus links." If you disable it, use the campus VPN or proxy your library documents.
Save, label, and alert — without mixing up your profile
Two Scholar features share a Google account and do different jobs. My library is the reading list. A Scholar profile is the public record of papers you wrote. Search Help separates them on purpose:
Google Scholar Search Help, How is my library related to my Scholar profile?
Your profile contains all the articles you have written yourself. It’s a way to present your work to others, as well as to keep track of citations to it. Your library is a way to organize the articles that you’d like to read or cite, not necessarily the ones you’ve written.
My library
Click Save under a result — not a star, which older screenshots still show. Open My library from the top of the page or the side drawer. Add labels, search inside the library with the ordinary search box, and delete items you no longer need. Only you can see the library. Making a profile public does not publish the library. Highlights from the PDF Reader also land here.
Google Scholar Search Help, How do I add an article to my library?
Find the article you want to add in Google Scholar and click the “Save” button under the search result.
Email alerts
You do not need a Google account. Search Help's topic example is "M Theory": run the search, click the envelope icon in the sidebar, enter any email, and click Create alert. If the address is not a Google account, Scholar sends a verification link. Alerts for a colleague work from their public profile (Follow → New articles by this author) or from author:"name" plus the envelope.
Profiles are optional for students
Create a profile only if you need citation alerts on your papers or a public publications list. Profile Help recommends a personal Google account so the profile survives a campus email change, and a verified university address if you want the profile eligible to appear in name search. The example name on that page is richard feynman. Scholar computes two windows, All and Recent, of three numbers only:
Google Scholar Profiles, citation metrics and account advice
We recommend that you use a personal account, not an account at your institution, so that you can keep your profile for as long as you wish.
We compute two versions, All and Recent, of three metrics - h-index, i10-index and the total number of citations.
A ∗ beside a Cited by count means the number includes citations that might not match the article. Treat profile metrics as Scholar's view of the web, not as a Web of Science extract. Broader metric caveats live on Citation metrics.
Public Access on a profile
If a profile is public, Scholar may add a Public Access section for papers it thinks a funder requires to be open. That list is extracted from acknowledgement text, not from a form you filled in. You can mark a wrong funder, a wrong date, or a paper that is not yours. You can also upload a PDF you have the right to share to Google Drive. The rest of the open-access landscape — Plan S, NIH 2025, DOAJ — is a different page.
Google Scholar Profiles, Public Access
The Public Access section of a Google Scholar profile contains the articles that are expected to be publicly available based on funding agency mandates.
The Google Scholar indexing system automatically extracts funding information from the acknowledgement sections of articles.
Cite and export — then verify
Click Cite under a result. Search Help documents the bibliography-manager half of that popup. On the settings page you can also show one-click import links for BibTeX (or hide them).
Google Scholar Search Help, Citation Export
Click the "Cite" button under the search result and then select your bibliography manager at the bottom of the popup. We currently support BibTeX, EndNote, RefMan, and RefWorks.
The same popup also shows copy-paste bibliography strings. University guides such as the American College of Greece Scholar guide list MLA, APA, Chicago, Harvard, and Vancouver in that window. Those strings are a starting draft. Scholar clusters versions, abbreviates authors, and sometimes cites a [citation] record. Open the paper, confirm the title, the authors, the year, the volume, and the DOI, then generate the citation you will submit. Import BibTeX or RIS if you already have an export file; find the DOI if Scholar omitted it.
Failure modes in the Cite popup
- Wrong version. The formatted line may point at a preprint while you read the journal PDF.
- Missing DOI or pages. Add them from the publisher page before you file the paper.
- [citation] only. There is no full text to check. Find the work in a library catalog or another index.
- Labs or Quick Read as the source. Cite the article those tools found, not the tool.
- Bulk harvest. Scholar will block automated scraping. Search Help will not raise the limit; it points at robots.txt.
Read the PDF in Scholar PDF Reader
The Scholar PDF Reader is Google's Chrome extension for article PDFs. The 10 November 2025 blog post is the current highlight-and-comment rule. Notes sync to My library, not to a public profile.
Google Scholar Blog, Mark it up! (10 November 2025)
Select the text you want to emphasize, and a popup will appear, allowing you to choose a highlight color or add a comment.
Highlights and comments are saved automatically to your personal Google Scholar Library.
If you don’t yet have the Reader, you can install it from its Chrome web store page. In addition to highlights, Scholar PDF Reader has many other features to help with your paper reading – AI Outline for quick overview, one-click preview of cited articles, linked figure and table mentions, citing and related articles, and light/dark modes.
The AI Outline is a skim, like Quick Read. Use it to jump to a section; do not quote the outline as if it were the paper. The Cite button inside the Reader has the same draft problem as the search-result popup: confirm the version of record before you paste.
Scholar Metrics are not your profile numbers
A profile shows your h-index, i10-index, and citation total. Scholar Metrics is a different product: five-year journal and conference visibility, for authors who are choosing where to publish. Open the Metrics browse list and sort by h5-index. As of 17 September 2026 the help page has not moved past the July 2025 snapshot — there is no 2026 Metrics release on the Scholar Blog yet. The 22 July 2025 post is still the current announcement.
Google Scholar Metrics Help, July 2025 snapshot
Scholar Metrics are currently based on our index as it was in July 2025.
Scholar Metrics currently cover articles published between 2020 and 2024, both inclusive. The metrics are based on citations from all articles that were indexed in Google Scholar in July 2025.
Finally, the h5-index, h5-core, and h5-median of a publication are, respectively, the h-index, h-core, and h-median of only those of its articles that were published in the last five complete calendar years.
Metrics exclude court opinions, patents, books, and dissertations, plus any publication with fewer than 100 articles (or no citations) in 2020–2024. Browsing by research area is English-only. If a journal is missing, Metrics Help says to search its abbreviated title — it has seen 959 ways to refer to PNAS. Do not treat an h5 number as a journal-quality stamp; use it as Scholar's five-year visibility view, then read Citation metrics for DORA and field-normalized caveats.
Case law is a separate collection
On the homepage or in the side drawer, choose Case law. Then use Select courts in the sidebar. Search Help states the coverage window:
Google Scholar Search Help, Which court opinions do you include?
Currently, Google Scholar allows you to search and read published opinions of US state appellate and supreme court cases since 1950, US federal district, appellate, tax and bankruptcy courts since 1923 and US Supreme Court cases since 1791.
Those opinions are informational. Search Help says they are not a substitute for advice from a licensed lawyer. For Bluebook citation of cases you already have, use How to cite legal cases or the law citation guide.
When Google Scholar is the wrong tool
MIT Libraries say it in one line: not everything is indexed in Scholar, so use a subject database. Scholar is strong for a first pass, a known title, a citation trail, a Labs question, and a free copy. It is weak when you need a documented, reproducible search or a peer-review limiter.
Use Scholar
- A known title or author
- Citation chaining from a seed paper
- A signed-in Labs question
- A free PDF or library resolver link
- Alerts on a query or an author
- U.S. court opinions in the Case law collection
Use a library database
- A comprehensive subject search
- Controlled vocabulary / thesaurus terms
- A peer-reviewed limiter you can report
- More than 1,000 viewable hits
- A documented systematic-review strategy
Two hard limits come from the vendors themselves. Search Help caps any query at 1,000 visible results. The Cochrane Handbook technical supplement to Chapter 4 (last updated September 2024, Handbook 6.5) treats that cap as a reproducibility problem:
Search Help result cap and Cochrane Handbook Chapter 4 technical supplement
Sorry, we can only show up to 1,000 results for any particular search query. Try a different query to get more results.
Finally, Google Scholar limits the number of viewable results to 1,000 and does not disclose how the top 1,000 results are selected, thus compromising the transparency and reproducibility of search results (Levay et al 2016).
Use Scholar to supplement a systematic review — grey literature, a forward citation search from a known trial — not as the only database. MEDLINE, Embase, and the subject index your librarian names remain the documented search. Scholar also adds new papers several times a week, but Search Help says updates to existing records can take 6–9 months to a year or longer. Labs does not remove that recrawl delay.
Settings that students actually change
Open Settings from the side drawer. The live settings page is where library links, language filters, and citation-import links live. Search Help explains why the page forgets you after a cookie wipe:
Google Scholar Search Help, How come you're forgetting my settings?
Technically, your web browser remembers your settings in a "cookie" on your computer's disk, and sends this cookie to our website along with every search.
- Library links. Up to five resolvers. Sign in if you want the choice on another browser.
- Bibliography manager. Show BibTeX (or EndNote / RefMan / RefWorks) import links under results, or hide them.
- Languages. Search pages in any language, or restrict the result language list.
- Collections. Include or exclude patents from article search; Case law is a separate collection.
- Signed-out off-campus access. The 30-day subscription recording. Turn it off if you will use VPN instead.
Mistakes this page is written to stop
- Treating every hit as peer-reviewed. Preprints, theses, and [citation] rows are in the same list.
- Skipping library links. The PDF you need may already be paid for by tuition.
- Citing the Cite popup unedited. Confirm the version and the DOI on the publisher page.
- Citing Scholar Labs or Quick Read. Those tools find papers. Cite the paper.
- Quoting a Quick Read or AI Outline as the article. Open the PDF for methods, tables, and retractions.
- Sorting by date for every search. Search Help prefers Since Year plus relevance.
- Confusing My library with a public profile. Saving a paper does not list you as its author.
- Confusing profile metrics with Scholar Metrics. One is your papers; the other is five-year journal visibility as of July 2025.
- Stopping at page one. Relevance ranking favors titles and citation counts; useful items sit deeper.
- Using Scholar as the only systematic-review database. The 1,000-result cap is a documented failure mode.
- Citing a retracted paper because Scholar still lists it. Search the title plus retracted, then check the publisher page before you cite.
Format the source after you have the real record
Once the publisher page or PDF is in hand, generate the citation from that record — not from a Scholar snippet, a Labs blurb, or a Quick Read card. Import a BibTeX or RIS file if you already exported one.
Frequently asked questions
- Is Google Scholar free, and is the full text free?
- Searching Scholar is free. Search Help says abstracts are freely available for most articles, but reading the entire article may require a subscription. Use a library link, a [PDF] or [HTML] link, All versions, or interlibrary loan. Quick Read appears only on papers you can already open.
- Are all Google Scholar results peer-reviewed?
- No. Search Help lists journal and conference papers, theses, books, preprints, abstracts, technical reports, court opinions, and patents. Inclusion guidelines exclude news, magazine articles, book reviews, and editorials as targets for the index, but you still have to check the item you opened. Scholar Labs does not add a peer-review filter.
- How do I search Google Scholar by author?
- Type author:"d knuth" or author:"donald e knuth" — Scholar's official examples. No space after the colon. Add a co-author or a topic word if the surname is common. Donald E. Knuth's public profile is a separate page from the author: operator.
- What is Google Scholar Labs?
- A signed-in search mode, launched 18 November 2025 and updated 3 June 2026, that takes a research question instead of a keyword string. It identifies topics, aspects, and relationships, then returns papers with a short note on how each one helps. As of the June 2026 post it is available to all logged-in users and accepts questions in all languages; the updated ranking launched in English first. Cite the papers it finds, not Labs.
- What is Quick Read in Google Scholar?
- A 25 August 2026 summary on Labs and ordinary search. Click Quick read for Answers, Approach, and Considerations focused on your query. It is limited to logged-in users, English articles, and papers you have access to. Use it to decide whether to open the PDF; do not cite the card.
- How do I connect Google Scholar to my university library?
- Menu → Settings → Library links, then search your institution and save. Settings allow up to five libraries. Harvard's public label is Harvard University — Try Harvard Library; MIT's is Massachusetts Institute of Technology Library - Full text: MIT Libraries. Resolver access still requires you to be a patron.
- What does Cited by mean in Google Scholar?
- It is a list of later scholarly works in Scholar's index that reference this item. High counts often mark influential or older work; they are not a quality stamp. Use Cited by when the first results are too general, and set an envelope alert on that list if you need new citing papers. Search Help's worked example is Witten's 1998 paper Anti de Sitter space and holography.
- What is the difference between a Scholar profile and Scholar Metrics?
- A profile lists papers you wrote and computes All and Recent values of h-index, i10-index, and citation total. Scholar Metrics ranks journals and selected computer-science conferences by h5-index for articles from 2020 through 2024, using the July 2025 index — still the live snapshot on 17 September 2026. Students writing a paper usually need neither; authors choosing a venue use Metrics.
- Can I use Google Scholar for a systematic review?
- Not as the only database. Search Help shows at most 1,000 results per query. The Cochrane Handbook Chapter 4 technical supplement (September 2024, Handbook 6.5) says that cap, plus undisclosed ranking of those 1,000, compromises transparency and reproducibility. Use subject databases for the reported strategy and Scholar only as a supplement. Labs does not make the search reportable.
- Why do some results say [citation] and have no link?
- Scholar saw other papers cite that work and has not found a full record online. Uncheck include citations in the sidebar to hide them. Do not treat a [citation] row as a source you have read.
