Published in 1994, this companion to Terry Pratchett's Discworld novels covers the first 17 novels only, which in all honesty renders this book rather obsolete beyond being anything other than an item to own for your Discworld collection.

There are two later editions, published after more Discworld had been invented and written, that include everything in this book and obviously more.

The information itself is concise and set out alphabetically, making it very easy to dip in and out as a reference book. Alongside are some primitive illustrations that don't really add much to the information to be completely honest.

Only necessary for those who collect Discworld or Terry Pratchett books. Otherwise, pretty much a pointless book.
