Numbers in parentheses refer to specific pages in the APA 6th Edition manual.
What Appears in the Reference List?
References cited in text must appear in the Reference list and vice versa. The only exceptions to this rule are personal communications and classical works (e.g. The Bible); they are cited in text only and are not included in the Reference list (p.174).
Double-Spaced
Your entire paper, including the Reference list, should be double-spaced. (p. 180)
Tip: Use your word processor's Help function to learn how to double-space your paper:

Hanging Indent
Each entry should be formatted with a hanging indent (p. 37).

Alphabetical
Arrange References entries in one alphabetical sequence by the surname of the first author, or by title or first word if there is no author (pp.181-183). Ignore the words A, An, and The when alphabetizing by title.
Capitalization
In titles and subtitles of articles, chapters, and books, capitalize only the first letter of the first word and any proper nouns (p.185).
Italics
Italicize book titles, journal titles, and volume numbers. Do not italicize issue numbers.
Author's Name(s)
Use only the initial(s) of the author’s given name(s), not the full name (p.184), even when the full name is given.
If the Reference list includes 2 or more entries by the same author(s), list them in chronological order with the earliest first (p. 182).
What if there is no author?
If the author’s name is unavailable, use the first few words of the title of the source, including the appropriate capitalization and italics formatting (pp.176-177).
Digital Object Identifier (DOI)
If a Digital Object Identifier (DOI) is listed on either a print or an electronic source it is included in the reference (pp.188-192). A DOI is a unique alphanumeric string that is used to identify a certain source (typically journal articles). It is often found on the first page of an article.
Example:
doi:10.1080/14622200410001676305
For more information on DOIs and locating a DOI on a source, check out pages 188-192 of the APA Manual and/or this helpful DOI flow chart from the official APA site.
URLs
When the References entry includes a URL that must be divided between two lines, break it at a logical division point, preferably before a slash or dash (p.192).
Abbreviations
