Here are some strategies for evaluating sources you're considering including in bibliographies.
What kind of source is this?
Journal article citations will usually include a volume number, issue number, year, and page numbers:
Collins, Patricia Hill. "Learning from the outsider within: The sociological significance of black feminist thought." Social problems33.6 (1986): S14-S32.
Book chapter citations from edited volumes will usually include 2 names or sets of names (the chapter author and the editor), the word "in," and either "edited by" or an abbreviated form (e.g. "ed," "eds").
Finley, Erin P. "War and Dislocation: A Neuroanthropological Model of Trauma among American Veterans with Combat PTSD." InThe Encultured Brain: An Introduction to Neuroanthropology, edited byDaniel H. Lende and Greg Downey, 263-90. Cambridge, MA: MIT Press, 2012.
Monograph (i.e. single-author book) citations are usually relatively simple, compared to other kinds of citations.
Cohen, Cathy J. Democracy remixed: Black youth and the future of American politics. Oxford University Press, 2010.
