Do a quick analysis of the material by looking for the author, publisher, and date of publication. You may need to do a couple of searches on the author and/or publisher to make sure that you uncover any possible issues that aren't immediately apparent just from looking at the material. For example, if a book is self-published by the author, it may be missing the high level of editing that is inherent in the corporate or academic publishing process.
