Uses of book reviews
Book reviews can be very useful in a number of ways during the research
process. They may often give information about the author, a summary of
the book's contents, comparisons to other works in the field, and of
course evaluative comments. Surveying many reviews can provide an
overview of the critical reception of a book. Reviews themselves can
range from one paragraph to several pages, from popular to scholarly.
They almost always come out in periodicals and/or newspapers within a year
or two of the book's publication.
