To find reviews of a book by an established author, you might start by checking the Libraries' catalog for a bibliography devoted to that author. To do this, search for: bibliography <author's name> and select "subject" from the pull down menu. Ex. bibliography wharton
In the event that there is not a bibliography available, then the following indexes of reviews may help.
The following indexes are located offsite (follow the links to the catalog records to see more details or make a request for an offsite book).
