Imagine taking all the facts, interviews, reviews and news related to (sometimes only peripherally) the first 21 years of Doctor Who, covering three of its main markets, trimming them down to a few per year, then organising them into a (sort of) diary format, presenting the history of the show in a series of snippets.
That's what you get with this book. The facts are a mix of the well and lesser known and there's little in the way of repetition. It's not a full history but, back in the eighties, it was pretty much all you got outside of the dedicated publications of the DWAS.
The main problem, for me, is the presentation - not only is the layout sometimes "off" with, for example, the date heading appearing on one page but the text entry on the next - but there's a lack, outside of a few colour pages, of photos, with the main picture content being a selection of fan art, which varies from excellent to really pretty poor.
For context, this was a re-read, chosen at random from my non-fiction shelf by my wife. I originally bought and read it on publication.
