Last-Minute Thesis Bibliography Checklist

Your thesis is written, your argument is solid, but your bibliography could still cost you marks. Use this checklist to catch formatting errors before you submit.

The 10-Point Bibliography Check

Run through each item before submitting. Most formatting deductions come from inconsistencies, not individual errors.

One style throughout – Every entry uses the same citation style (APA, MLA, Chicago, Harvard). Mixing styles is the most common reason for lost marks. If you inherited entries in different formats, use a tool to convert citations between styles before submitting.
Alphabetical order – APA, MLA, and Harvard reference lists are alphabetized by first author’s last name. Chicago bibliography entries follow the same rule. IEEE and Vancouver use numbered order of appearance instead.
Hanging indent – Every entry after the first line should be indented 0.5 inches (1.27 cm). In Word: highlight all entries, go to Paragraph > Special > Hanging.
Double spacing – Most styles require double spacing between and within entries. Check your department’s guidelines – some allow single spacing within entries.
Author names formatted correctly – APA uses initials (Smith, J. D.), MLA uses full names (Smith, John David). Check every entry matches your style.
Italics in the right places – APA and MLA italicize book titles and journal names. Article and chapter titles aren’t italicized in any major style.
DOIs and URLs present – If a source has a DOI, include it. Format: https://doi.org/10.xxxx/xxxxx. No “Retrieved from” prefix in APA 7th.
Dates are consistent – APA uses (2025). MLA uses day-month-year (15 Mar. 2025). Chicago spells out months. Pick your style’s format and stick to it.
Every in-text citation has a reference entry – Search your paper for each parenthetical citation and confirm it appears in the bibliography. Then check the reverse – every bibliography entry should be cited in the paper.
Page numbers and volume numbers – Journal articles need volume, issue, and page numbers. Books need publisher and year at minimum. Missing fields are easy to overlook.

Auditing a Messy Entry: A Worked Example

Suppose one entry in your APA bibliography currently reads:

Smith, J., “The impact of citation accuracy on academic publishing”, Journal of Academic Writing, 2025.

Checked against the list above, this entry fails on three separate points: the article title sits in quotation marks rather than plain sentence case (APA never quotes article titles), the journal name isn’t italicized, and the volume, issue, and page numbers are missing entirely. Corrected:

Smith, J. (2025). The impact of citation accuracy on academic publishing. Journal of Academic Writing, 15(3), 45–62. https://doi.org/10.1234/example

Running every entry through this same three-step check – title formatting, italics placement, and completeness of the numeric fields – catches most of the deductions a marker takes off for “inconsistent formatting.”

Style-Specific Quick Checks

APA 7th Edition

Title of article in sentence case (only first word capitalized)
Journal name in title case and italics
DOI as a hyperlink, no period after it
“et al.” after first author for works with 3+ authors (in-text)

APA Style publishes free reference examples directly if you need a specific source type confirmed beyond this checklist.

MLA 9th Edition

Titles of articles in quotation marks, title case
Container titles (journals, websites) in italics
No URLs unless the source can’t be found without one
Publisher name included for books

Chicago (Notes-Bibliography)

Footnote format differs from bibliography format
Shortened footnotes for repeat citations
“Ibid.” for consecutive citations of the same source
Bibliography entries invert only the first author’s name

The Chicago Manual of Style is the authoritative source for the full notes-bibliography and author-date rules.

Harvard (Cite Them Right)

Article and chapter titles sit in single quotation marks, not italics
Editors named inside an “in ... (eds)” clause keep their normal name order – never invert them the way you’d invert the chapter’s own author. Note the plural form also drops the period Harvard keeps for a single editor’s “(ed.)”
Access dates apply only to sources with no DOI; drop the access date entirely once a DOI is present
Edition noted as “3rd edn.,” not “3rd ed.”

IEEE and Vancouver

Reference list ordered by first appearance in the text, not alphabetically
Author initials come before the surname in IEEE (J. D. Smith); Vancouver drops the periods entirely (Smith JD)
Double-check every in-text bracketed number against the final reference list – renumbering after a late edit is the most common error in either numbered style

Troubleshooting: Sources That Don’t Fit the Checklist Cleanly

A source with no DOI and no clear public URL. If you found the source through a subscription-only library database, cite the database name in place of the broken subscription link, rather than a URL nobody outside your university can open.
A source you found quoted inside another paper. Cite it as a secondary source – your style’s “as cited in” or “cited in” convention – and add only the secondary source, the one you actually read, to your reference list. Never add a reference-list entry for a source you haven’t personally accessed.
An edition your library only holds in an older printing. Cite the edition you actually used, not the book’s current edition. A bibliography entry citing a 2015 printing of a book now in its 4th edition is accurate, not outdated, as long as your page numbers match the copy you read.
A source in a language other than English. Keep the title in its original language, and add a bracketed English translation immediately after if your department or style requires one.
A web source with missing author or date fields. If your bibliography includes web sources like this, our guide to citing a website covers the exact fallback format each style uses when either field is missing.

Common Mistakes

For an exhaustive list, see our common citation mistakes guide. The ones that hit thesis students hardest:

Citing sources you didn’t read – If you found a quote in another paper, cite both the original and the secondary source
Wikipedia in the bibliography – Use Wikipedia to find primary sources, then cite those instead
Outdated editions – Make sure you’re following the current edition of your citation style
Inconsistent publisher locations – Some older style guides required city of publication; most current editions don’t
