So with these criteria in mind, let's look at the second to last citation and identify the elements:
What else is included? It looks like there is another title, along with a bunch of numbers. This must be a journal article.
Our first citation is an article by William B. Thompson entitled "Black Intellectuals, Intelligence Testing in the 1930s and the Sociology of Knowledge" which was published in the periodical Teachers College Record in 1984, volume or issue number 85, on pages 477-501.
The next step is to look up the name of the Journal to see if we subscribe to it, and if we do, what years and in which databases we have access.
