Another current book of advice for reviewers. Highly recommended for its perspective on the value of high quality book reviewing.

Another older source and the information about the book pubishing industry is certainly dated. But their are some particularly good insights about the relationships between book reviewers and book authors.

This is an excellent writing guide that focuses on the kind of short, focused writing needed for online reviews. Strunk and White for the digital age.

Once readers get past the almost insulting title, they learn to be better readers on a deeper level. While reading this book you may have the same experience I had with one of my daughters -- a child laughing at you for reading a book that tells you how to read a book. "How did you know to read that one, Dad?" :)

Another older source, but written by an expert in the process of analyzing texts and producing accurate and useful summaries. Worth reading to help book reviewers strengthen this part of their task.

A readable introduction to the concepts of automated text summarization--how computer programs produce brief summaries of book-length texts. Part of a book reviewer's task is to do this very thing, so we can learn something from the strengths and weaknesses of software approaches.

This is a general textbook in methods used in evaluation. Many of them are not relevant to book reviewing--but there are some perspectives on how an evaluator using "expert judgment" can be disciplined and fair.
