If you use information from multiple pages on a website, create a separate reference list entry for each page, with in-text citations that correspond to the appropriate reference list entry. It is common for writers to have multiple entries with the same author and year , so to differentiate these entries, use a letter after the year (., 2016a) or after .

Put references with no date before references with dates, and put in-press references last.
Sample papers in the first printing of the sixth edition contained errors. APA staff posted all of the corrections online for free in a single document on October 1, 2009, and shortly thereafter alerted users to the existence of the corrections in an APA blog entry.

All copies of the printing with errors were soon after recalled in 2009 (including those from major retailers such as ) and all manuals currently in circulation are unaffected.
