A bibliography is a list of sources — books, articles, websites, theses — that you consulted or cited during your research. Writing a correct bibliography is essential for academic credibility, avoiding plagiarism, and allowing readers to verify your sources. This guide covers every major citation style with step-by-step format examples.

Use Reference Management Software to Save Hours
Manual bibliography formatting is error-prone and time-consuming. Use free reference managers: Zotero (free, browser plugin, exports APA/MLA/Chicago/Harvard instantly), Mendeley (free, PDF organiser, generates bibliography), or Google Scholar's "Cite" feature for quick citations. These tools auto-generate correctly formatted bibliography entries — you just collect references as you research and generate the bibliography with one click.

A bibliography is a complete list of all sources consulted or cited during the course of research — including sources that informed your thinking even if not directly cited in the text. In academic writing, a bibliography is placed at the end of the document. It differs from a 'References' list (APA/MLA) which only includes sources directly cited in the text. A bibliography may include annotated descriptions of sources (annotated bibliography).
A References list (used in APA and MLA styles) includes only sources that were directly cited (in-text) in your paper. A Bibliography (used in Chicago/Turabian style, and some Harvard guides) includes all sources consulted — both cited and uncited (sources that informed your thinking even if not quoted). In practice, many Indian universities use 'bibliography' and 'references' interchangeably. If your citation style is APA or MLA, use 'References'. If it's Chicago or Harvard, use 'Bibliography'.
APA 7th Edition bibliography (References) format: (1) Book: Author, A. A., & Author, B. B. (Year). Title of work: Capital letter also for subtitle. Publisher. (2) Journal article: Author, A. A. (Year). Title of article. Title of Journal, volume(issue), page–page. DOI. (3) Website: Author, A. A. (Year, Month Day). Title of page. Site Name. URL. All entries are in alphabetical order by author's last name, with a hanging indent (second line indented 0.5 inches).
MLA 9th Edition Works Cited format: (1) Book: Last Name, First Name. Title of Book. Publisher, Year. (2) Journal article: Last Name, First Name. "Title of Article." Journal Name, vol. #, no. #, Year, pp. #–#. DOI or URL. (3) Website: Author (if given). "Title of Page." Site Name, Day Month Year of publication, URL. MLA uses the label 'Works Cited' (not 'Bibliography'). Entries are alphabetical by author last name with hanging indent.
Harvard referencing bibliography format: (1) Book: Author surname, Initial(s). (Year) Title of book. Edition (if not first). Place of publication: Publisher. (2) Journal article: Author surname, Initial(s). (Year) 'Title of article', Journal Name, Volume(Issue), pp. page–page. (3) Website: Author/Organisation. (Year) Title of page. Available at: URL (Accessed: Day Month Year). Harvard uses 'References' or 'Bibliography' — institutions vary. Entries are alphabetical by author surname.
An annotated bibliography is a bibliography where each entry is followed by a brief annotation (100–200 words) that: (1) summarises the source's main argument or content; (2) evaluates the source's credibility, methodology, or relevance; (3) explains how the source relates to your research topic. Annotated bibliographies are commonly assigned in undergraduate and postgraduate courses to develop critical reading skills. They help readers understand why each source was selected.
