If your reference list looks disorganized, it implies carelessness on your part.
Three Ways to Point Readers to a Source

Author-date. You place the author’s surname and the year inside your sentence. Readers then find the full details in an alphabetical list at the end.
Numbered. You put a number in the text. That number matches an entry in the reference list. The list is usually ordered by first appearance.
Footnote or endnote. You add a small raised number after the claim. The complete citation is provided below the text on this page or at the end of the text.
Choosing the Correct Citation Style
This is how you should prefer sources:
- Refer to the guidelines for your paper or journal article. If a style is recommended there, stick to it.
- If no style is named, look at your field. Each discipline has a favorite.
- Consult your boss if you have any doubts.
- Once you choose, stay with it from the first page to the last.

Numbered Citation Styles
Numbered systems save space. As a result, they are favored in technical and medical writing.
- ACS is used in chemistry.
- AMA is the standard in many medical journals.
- IEEE is the norm in engineering and computer science.
- NLM and Vancouver are common in biomedical and health research.
- CSE citation-sequence is an alternative for the life sciences.
Footnote Citation Styles
Footnote systems suit subjects where sources need comment or explanation.
- Chicago notes and bibliography is popular in history and the arts.
