Reviews are usually published within five years of a book's publication. If you need a review of a book published in 1960, chances are good that you will not find a review in a database with coverage beginning in 1980.
Try searching for the author's last name and the title of the book - author's first names are often not indexed.
When was the book published? Most online book review resources only cover the last decades of the 20th century to the present. Reviews of older materials will often be in print publications.
Do you need a review of a popular novel? Use a source that covers popular materials rather than scholarly journals.
