APA Style (7th edition) : Basic Rules ( for most sources)
All lines after the first line of each entry in your reference list should be indented one-half
inch from the left margin. This is called hanging indentation.
All authors' names should be inverted (i.e., last names should be provided first).
Authors' first and middle names should be written as initials.
For example, the reference entry for a source written by Jane Marie Smith would
begin with "Smith, J. M."
If a middle name isn't available, just initialize the author's first name: "Smith, J."
Give the last name and first/middle initials for all authors of a particular work up to and
including 20 authors (this is a new rule, as APA 6 only required the first six authors).
Separate each author’s initials from the next author in the list with a comma. Use an
ampersand (&) before the last author’s name. If there are 21 or more authors, use an
ellipsis (but no ampersand) after the 19th author, and then add the final author’s name.
Note An ampersand (&) represents "and," while an ellipsis (...) indicates omissions
Reference list entries should be alphabetized by the last name of the first author of each
work.
For multiple articles by the same author, or authors listed in the same order, list the
entries in chronological order, from earliest to most recent.
When referring to the titles of books, chapters, articles, reports, webpages, or other
sources, capitalize only the first letter of the first word of the title and subtitle, the first
word after a colon or a dash in the title, and proper nouns.
Note again that the titles of academic journals are subject to special rules ( refer
the section below Basic rules for academic Journals )
Italicize titles of longer works (e.g., books, edited collections, names of newspapers, and
so on).
Do not italicize, underline, or put quotes around the titles of shorter works such as
chapters in books or essays in edited collections.
Basic rules for academic journals
Present journal titles in full.
Italicize journal titles.
Capitalize all major words in the titles of journals. Note that this differs from the rule
for titling other common sources (like books, reports, webpages, and so on) described
above.
This distinction is based on the type of source being cited. Academic journal titles
have all major words capitalized, while other sources' titles do not.
Capitalize the first word of the titles and subtitles of journal articles, as well as
the first word after a colon or a dash in the title, and any proper nouns.
Do not italicize or underline the article title.
Do not enclose the article title in quotes.
So, for example, if you need to cite an article titled "Deep Blue: The Mysteries of
the Marianas Trench" that was published in the journal Oceanographic Study: A
Peer-Reviewed Publication, you would write the article title as follows:
Deep blue: The mysteries of the Marianas Trench.
...but you would write the journal title as follows:
Oceanographic Study: A Peer-Reviewed Publication
