Very nice book! Maybe a bit more for the beginner, or generalist, but also the experienced user and specialist will find tons of interesting information in it.
"The Timex Sinclair User's Encyclopedia" by Gary Phillips and James C. March is a huge, extended glossary of pretty much everything you can think of regarding the Sinclair ZX81, Timex Sinclair 1000, and Timex Sinclair 2068. It covers manufacturers, peripherals, hardware components, software titles, BASIC keywords, algorithms, binary logic, IT terminology, abbreviations, and what not else, each with at least fundamental information, and in most cases with some extra bits, like some example code, or further keywords. With more than 200 pages, it really has a lot of content. If you're looking for something ZX81 (up to 1984, and a little beyond), you'll definitely find it in this book. And if you don't, you can still easily spend many hours browsing through the pages.
