Dear APA Style Experts,
I’m a computer science major, and my favorite blog is called Gödel’s Lost Letter and P=NP, written by two esteemed computer science experts. Can I cite a post from that blog? I’m also writing a paper for my Introduction to Psychology class, and I want to cite the APA Books Blog. Can I?
Yes. You can create an APA Style reference to any retrievable source, though you should of course consider whether the source is reliable, primary, and timely.
Citing an Entire Blog
First, if you want to mention the blog as a whole, just include a mention of it in parentheses in your text, just as you would for mentioning an entire website.
I really enjoy reading the new APA Books Blog (http://blog.apabooks.org).
I have learned a lot by reading the Psych Learning Curve blog (http://psychlearningcurve.org).
Note: In the first case, the word Blog is capitalized because Blog is part of the name (APA Books Blog). In the second example, blog is not part of the name (Psych Learning Curve).
However, if you are quoting or paraphrasing part of a blog post, you should create a reference to that specific post.
The elements of the reference are as follows:
"who": This is usually one or two people but can also be a company name or other type of group author. In the first example below, the post was credited to just “Freakonomics” (a screen name for the author or authors of the blog by the same name). If a byline is not evident, look at the beginning or end of the post for wording like “posted by.”
"when": Blog posts generally provide the year, month, and date. Include these within the parentheses in your reference. If the blog doesn’t give that level of detail, just include the year or year and month, if that’s all you can find. (Note that your in-text citation will include only the year; see the examples below).
"what": This it the title of the blog post followed by a notation of "[Blog post]."
"where": Use “Retrieved from” and the URL of the blog post.

rjlipton. (2015). A fast graph isomorphism algorithm [Blog post]. Retrieved from https://rjlipton.wordpress.com/2015/11/11/a-fast-graph-isomorphism-algorithm/
The name of the blog itself is not part of the reference, although it's often evident from the URL.
As with other APA Style references, the in-text citations will match the author name(s) and the year.
Example In-Text Citations
... according to research on the health effects of the E-ZPass (Freakonomics, 2010).
Heasman and Corti (2015) wrote about an echoborg.
Mathis (2015) stated that...
Dr. Lipton noted two problems (rjlipton, 2015).
I hope you found these examples helpful! In my next post, I’ll discuss how to cite reader comments on a blog.
