The Penguin Book of Card Games (1979)

This book by David Parlett sets out rules for a very large selection of games. The book is laid out by 'families' of games and details main rules for each game plus a plethora of variations. It also includes an introduction to card games and a glossary of terms.
The latest edition (from 2008, cover pictured) also includes some original games by David Parlett and some tarot games.
