My aim here is to give you information about good books on crosswords, in well-chosen categories which should help you find books quickly. The crosswords I'm interested in are mostly, but not exclusively, cryptic crosswords. I've been trying to solve these since the mid-1970s. It took a while, but I'm now very good at it - good enough to have appeared in every final of the Times Crossword Championship since 1996, and to win a couple of times. But I remember the days when I found puzzles difficult, and spend some of my crossword time helping less experienced solvers in various ways - at present mainly by contributing to blogs where the best-known daily paper puzzles are analysed and discussed. I use this experience in assessing books, as well as my direct solving experience. My intention is to review available books once a month to ensure that the information here is up-to-date.
