Big Brother has been keeping a close watch on the Sinclair software market, and now he's put it all down on paper. 'The Complete Sinclair Database' by Big Brother Publications is the result.

The book is a compilation of software and hardware reviews, together with brief sections on Sir Clive Sinclair, Spectrum history, and fault-finding.

At £6.95 this book doesn't look a very promising buy. There are 114 games reviews, but the market changes so quickly that these will soon be out of date. Updates will be available but these will cost about £2.00.

The hardware sections might be more useful, but glancing through the ads of the popular magazines will probably give you as good an idea of the market, and a more up-to-date one at that.

Book publishing is an expensive and lengthy business, and the Spectrum software market is fast and cheap. 'The Complete Sinclair Database' falls uneasily in the middle. There are better ways of spending £6.95.
