The best way to find book reviews for your novels is by using a PRINT REFERENCE book:
Book Review Index REFERENCE Z1219 .B63
It is in the REFERENCE book shelves -- on the main floor across from the Library Service Desk.
You will have to look through several volumes to find all the reviews for your book. Start with the year your book was published and then look at the following years until you get no more reviews.
So how do you find a review listed in the BRI?
These library databases provide access to SOME book reviews and critical reception of literary authors (and other things too)! You will probably have too look at the biographical information or work overviews to find the critical reception information.
