Reference list, bibliography or works cited?

The short answer, because most people arrive here needing exactly this:

The distinction that actually matters is not the name. It is whether the list includes things you read but never cited.

Reference list: only what you cited

A reference list is a lookup table. Every in-text citation in your essay must have an entry, and every entry must correspond to at least one in-text citation. It is a strict one-to-one relationship in both directions.

That second direction is the one students break. A source you read, found useful, decided not to quote, and left in the list is an error in APA, MLA and Harvard — not a bonus. The list is there so a reader can find the thing you cited, and an entry with nothing pointing at it has no job.

This is also the single most common source of lost marks in referencing, and it is mechanical rather than a matter of judgement — which means it is worth ten minutes at the end, every time.

Bibliography: what you read

A bibliography is a record of your reading. It can include works you consulted, found useful for background, or read and rejected, whether or not any of them appear in the text.

It survives mainly in Chicago’s notes-bibliography system, which is what history departments usually mean by Chicago. There, footnotes carry the citations and the bibliography at the back lists the sources — including some the footnotes never touch.

Some departments in the humanities also ask for one alongside a reference list, on the grounds that showing what you read is part of showing your work. If yours does, they will say so in the handbook. If it does not say so, you want a reference list.

Works cited: MLA’s name for a reference list

MLA calls it Works Cited, capitalised, and the name is the definition: works that were cited. Functionally it is a reference list.

MLA also recognises Works Consulted for the bibliography case — everything you read — but it is rare, and you should only use it if asked.

The three mistakes worth checking for

Padding the list

Adding sources you did not cite, on the theory that a longer list looks more researched.

Markers check. It takes seconds with a text search, and finding three entries with no in-text citation tells them something specific about how the essay was assembled. In APA, MLA and Harvard it is straightforwardly an error.

Citing something that is not in the list

The reverse, and much more common, because it happens by accident: you cite something in a draft, keep the citation through an edit, and the entry never got added.

This one is worse than padding, because a reader who wants to follow up cannot. It is also the failure a generator prevents best — if every source is captured as you read, nothing can be cited without an entry existing.

Mixing the naming with the style

An APA essay whose list is headed Bibliography, or an MLA essay headed References. Harmless in meaning, and immediately visible as a mistake to anyone who marks in that style. Use the heading your style specifies, spelled and capitalised the way it specifies it.

What about “further reading”?

A separate thing again, and legitimate where it is asked for. A further-reading list is explicitly not part of your referencing: it points a reader at where to go next. Keep it under its own heading, after the reference list, and do not let it blur into either of the other two.

Ordering and formatting

All three are alphabetical by the author’s surname in every style discussed here. The differences are in the details:

• APA and Harvard use sentence case for titles and put the year straight after the author
• MLA uses title case and puts the date at the end
• Chicago’s bibliography uses title case and inverts only the first author’s name

Each style also has a rule for a source with no author, which is where the alphabetising gets interesting — the title takes the author’s place, so it is the title you alphabetise by. Our guide on citing a website with no author covers what happens to the entry itself.

Getting the list out

Once your sources exist as structured data — author, title, year, publisher — producing any of these lists is mechanical. Our citation generator holds sources that way and renders the list in APA 7, MLA 9, Chicago or Harvard, with the right heading and the right ordering for each, and switching style rewrites the whole list at once.

It also imports from RIS and BibTeX, so references already in Zotero, Mendeley or EndNote come across rather than being retyped.

One caution that applies to every generator: read the finished list before you submit. Automatic sentence case cannot reliably tell a proper noun from an ordinary word, and it is your name on the essay.
