Evaluating Books
Not all books are created equal. Some are written to entertain, some to argue and some to inform. Some might do all three. It's your job as a researcher to learn how to recognize which of these categories a book falls into and whether or not it meets your research needs.
These are the things you need to consider when evaluating books:
1. Authority
Who are the authors or editors? Are they experts in the subject matter of the book?
Who is the publisher? Was the book published by a commerical, specialty, vanity or university press?
2. Accuracy
Is the information in the book correct and accurate? Can the facts be verified?
Does the book contain footnotes and/or a bibliography? Are the sources properly cited?
3. Objectivity
What is the purpose of the book: to inform, to persuade or to entertain?
Is the book based on fact or opinion?
4. Currency
When was the book published?
Is the information up to date or is the information timeless?
5. Coverage
Who is the intended audience: the general public, students or scholars?
Does the book contain information relevant to your subject?
Does the book provide comprehensive coverage of the subject matter?
See the Evaluation Tips in the sidebar to learn how to gather the information you need to evaluate a book.
