If there is a criticism of a book, concrete reasons should be stated. The same is true for praises. Enough bibliographic information should be provided so that the reader may be able to find the book easily. If the publisher has their catalogue on the Internet or the capability of taking orders via the Internet, please mention it. Illustrated, index, glossary, maps, notes.
Readers are very astute and opinionated themselves.
They will catch the most minor errors and roast you for them. This is not an area for book publicity or promotion, but book information and criticism. Since almost every college and many public schools in the United States has an Internet connection, professors and teachers use rec.arts.books.reviews to look for recommendations for textbooks to use in their classes. If a book is particularly useful as a textbook, please indicate so. Technical and business books may be recommended for corporate libraries.
