How to Cite a Lab Manual

Quick Answer: how to cite a lab manual

Decide first whether the manual was published. If it has a publisher, an edition, and an ISBN, cite it exactly as you would a book. If it exists only as a departmental PDF, a bound course pack, or a Canvas upload, cite it as an unpublished course work: the instructor or department is the author, the university is the publisher or affiliation, and APA adds a bracketed description. In every style, point the reader to the experiment you used with a page number, or with the experiment number when the manual has no page numbers.

Which kind of lab manual do you have?

Open the front matter before you open a citation generator. The three questions below decide the template, and they decide it the same way in every style.

1. Is there a publisher and an ISBN? A copyright page naming a commercial or university press, an edition statement, and an ISBN mean the manual is a book. Cite it as one. Custom-printed manuals sold through a campus bookstore usually still carry a publisher line; check it.
2. Was it written for one course and never published? A departmental PDF, a spiral-bound handout, or a Canvas upload with no publisher is an unpublished course work. The department or instructor is the author and the university is the affiliation.
3. Is the experiment reprinted from somewhere else? Course packs often reproduce a chapter from a published manual. When the original source is printed on the page, cite the original; the course pack is only where you happened to read it.
4. Did the procedure come from outside the manual? A protocol you followed from protocols.io, a supplier's technical bulletin, or the methods section of a published paper is cited as what it is: an online work, a report, or a journal article. The last section of this guide shows how to name those inside your own methods section.

APA 7: a book, an unpublished work, or a classroom source

APA 7 has no lab-manual template because it does not need one. A published manual follows the book reference pattern. An unpublished manual follows the pattern for unpublished works: title, a bracketed description, then the department and university that hold it. Which of those you use depends on the recoverability test that APA applies to every classroom or intranet source: if your readers can retrieve the manual, write a reference entry; if they cannot, cite it as a personal communication in the text only.

Published lab manual

Treat it as a book. Put the edition in parentheses after the title, with no italics on the edition, and end with the publisher. APA 7 no longer lists the publisher's city. If the manual accompanies a textbook, cite the manual by its own title and authors, not the textbook's.

Unpublished departmental manual

When the department wrote the manual and never published it, the reference follows APA's unpublished-work pattern. The author is the person or department named on the cover. The title is italicised because the manual is a standalone work. The bracketed description tells the reader what the item is; APA §9.21 asks for a description in square brackets whenever the work falls outside the standard categories, and "Unpublished lab manual" says exactly that. The source is the department and university. When the department is also the author, do not repeat it as the publisher; give the university alone.

If the manual lives on a learning management system rather than in a handout, APA treats it as a classroom source that your classmates and instructor can retrieve. Name the LMS as the source and give the login page, not the deep link behind the password. The bracketed description stays, because the file is still a lab manual. This is the same pattern APA uses for PowerPoint slides on an LMS.

The audience matters. A lab report submitted to the same course has readers who can open the file, so the reference entry is correct. A manuscript sent to a journal has readers who cannot, and APA's classroom-sources rule then treats the manual as a personal communication: (M. Petrov, personal communication, February 3, 2024) in the text, with no reference entry. In practice a journal manuscript should cite the published method the manual was adapted from instead; see the methods section below.

Course-pack manual

APA Style has no dedicated course-pack example, so the reference is built from two existing rules. If the experiment is a reprint of a published manual, cite the published manual; the reprint note on the course-pack page gives you the details. If the experiment was written for the course and exists only in the pack, cite it as a part of a larger unpublished work, the way APA cites a chapter in a book, with the pack as the container and the department as the source.

Citing one experiment or section

APA's author-date rules let you cite a specific part of any source: a page, a paragraph, a section heading, a chapter, a table, a figure, or a slide. A lab manual with page numbers takes p. or pp.. A manual without them takes the part the reader can find, and an experiment number is that part. Write it in the text the same way you would write a chapter.

MLA 9: the university is the publisher

MLA 9 builds every entry from the same core elements, so a lab manual is a matter of filling them in correctly. The MLA Style Center says to begin with the author if the author of a handout or other course material is known, to check that the instructor really wrote it before listing them, and to style a standalone handout's title in italics. For a departmental manual, the university (or the department, then the university) is the publisher. A published manual is simply a book entry with an edition.

Unpublished departmental manual

Italicise the title because the manual is a standalone work. Put the department and university in the publisher slot. If the manual names no author at all, begin with the title; MLA does not list a department as author when that same department is the publisher. The year is the year printed on the manual, usually the academic year it was issued.

The Style Center's post on slide presentations uploaded to an LMS is the model: the LMS is the container, the upload date is the date, and the format can go in the optional-element slot at the end. The course-materials post adds one caution: if the platform only links out to a file hosted elsewhere, it is a passive conduit and should not be cited as a container.

Course-pack manual

MLA addresses course packs directly. The Style Center says a course pack may be cited more than one way and tells students to ask the instructor. Its own example cites the pack as the container, with the compiler, the term, and the university. Without instructions, cite the original source when it is known. For an experiment that exists only in the pack, cite the pack.

Chicago 18: notes for unpublished manuals

Chicago 18 draws the same line APA does, but it draws it with typography. A published manual is a book: italic title, publisher and year in parentheses in the note, page number after. An unpublished manual gets its title in quotation marks, not italics, followed by a parenthetical description that says what it is and where it is held. CMOS 18 no longer requires a place of publication for books, which is why the notes below run straight from the title to the publisher. The Notes-Bibliography guide and the Author-Date guide carry the book patterns these follow.

Unpublished departmental manual

Chicago's pattern for unpublished manuscripts is the model. The title goes in quotation marks. The description in parentheses names the kind of document, the department and university that hold it, and the year. If the manual is a PDF on a learning management system, you may add the platform after the page number so a reader knows where to ask for it.

Chicago handles a course pack the way it handles any compilation: cite the original publication when the pack reprints one, and otherwise cite the experiment as an unpublished piece inside the pack. Chicago's citation guides say nothing specific about course packs, so keep the description plain and complete.

Lab protocols from protocols.io

A protocol on protocols.io is not a manual and should not be forced into a manual template. Each protocol is a versioned online work with its own DOI, and the DOI changes with the version, so cite the version you followed. The title is italicised in APA because the protocol is a standalone work; MLA and Chicago put it in quotation marks because the site is the container. Use the DOI, not the page URL, in all three styles; see how to use DOIs for APA's DOI format.

Citing a procedure inside a methods section

A methods section cites the source of a procedure, not the sentence you copied from it. The rule that reviewers apply is simple: if you followed a written procedure, cite it; if you changed it, say what changed and still cite it. Three habits keep this honest.

• Cite the manual when the manual is the source. "Titrations followed the procedure in Experiment 7 of the departmental manual (Department of Chemistry, 2024)" is a complete, correct sentence in a lab report. Do not paraphrase the manual's steps without the citation, and do not quote them at length; describe what you did.
• Cite the published method behind the manual when you can find it. Most teaching protocols are adaptations of a published method, and a manuscript for readers outside the course should cite that paper or protocol. The manual's own reference list, or the instructor, will tell you what it was adapted from.
• Say "adapted from" when you changed anything. "DNA was extracted following Nakamura and Osei (2023), with the lysis step extended to 15 minutes" tells a reader exactly which steps are yours. Chicago and MLA use the same sentence with their own citation forms.

Quick comparison

Common mistakes

• Citing the textbook when you used the separate lab manual. They have different authors, titles, and page numbers.
• Pasting the Canvas deep link into an APA reference. APA wants the LMS login page; MLA wants the URL the reader would actually open.
• Italicising an unpublished manual's title in Chicago. Chicago italicises published titles and puts unpublished ones in quotation marks.
• Listing the department as MLA author when the same department is the publisher. Begin with the title instead.
• Citing protocols.io without the version. The DOI changes with each version, so an unversioned citation points at a procedure you may not have followed.
• Writing a methods section that reproduces the manual's steps with no citation. Describe what you did and cite where the procedure came from.
• Using n.d. for a manual that prints an academic year on its cover. "2023–2024" is a date; use the later year, or the year on the copyright line if there is one.
• Building a reference entry for a manual your readers can never obtain. In APA that case is a personal communication; better still, cite the published method the manual adapted.
