Scholarly books can be an important source of information. Although the most recent research tends to be published as peer-reviewed journal articles, scholarly books often expand on and synthesize this research and can present important conclusions about it. In addition to the book-length study, important dissertations may be published as books. Another popular format is a book of essays by various contributors, built around a common theme or as conference proceedings. Identifying scholarly books is not as easy as checking off a "peer-reviewed" box in an article database. Look for the credentials of the author(s), the publisher (usually, but not invariably, an academic or university press), and the general academic style of writing and documentation.
