Evaluating Books and Journal Articles
Whenever you use information, you should consider its source. Not all information is equally valid, accurate, timely, or complete.
If you are not familiar with the subject matter or author of a particular book, consider looking for book reviews to help you determine its value. Choose your reviewing sources carefully -- steer away from the more popular journals. The New York Times Book Review is a good choice rather than Publisher's Weekly.
For insights, go to journals in the subject field and those published by professional organizations such as the American Psychological Association or Organization of American Historians. Reference tools such as Book Review Digest and Book Review Index can help you locate reviews more easily. Some reviews are also available through full-text online databases such as Academic OneFile.
These questions will help you determine whether the books and journal articles you have found are appropriate for your needs.
