There are many, many French verb books in existence, which offer explanations and conjugations for hundreds - sometimes thousands - of verbs. In my mind, there are only a few contenders for your French reference library.
Subtitled La Conjugaison de 12 000 verbes
, this is the best French verb conjugation reference, bar none. Instead of wasting space with hundreds of identical conjugations, Bescherelle has pared down the conjugations to the bare minimum: one page each for regular -er, -ir, and -re verbs; a page apiece for passive and reflexive conjugations; and then 77 pages of irregular verbs. Once you memorize these 82 patterns, you can conjugate virtually every French verb that exists. French only.
Same as above, except verb translations and explanations are provided in English.
This is a very popular French verb book, and it's fine up to a point. But there are two things to keep in mind. (1) There is no need to have hundreds of French verbs conjugated into 14 tenses - there are many patterns, which the Bescherelle displays and explains much more clearly. (2) Some of the supplementary material is unclear or incorrect. If you just want lots of conjugations, this book is fine, but I strongly recommend against using it to learn grammar.
