How to solve cryptic crosswords - tutorial books

The list author says:
	"Listed first as it's the best guide for learning how to solve daily paper cryptics.  Most of the tips apply to all cryptics, not just the Times."

The list author says:
	"Less detailed than Moorey and others on how to solve, but tells you how to set and edit puzzles, and covers barred-grid cryptics too."

The list author says:
	"A guide by Val Gilbert, former Daily Telegraph crossword editor - I don't own it but it looked very sensible when last seen in a bookshop."

The list author says:
	"Guardian-based guide by their xwd editor - not 100% accurate on technicalities, but fun to read"

The list author says:
	"I don’t own this but I believe does a sound job. Both authors have set Listener puzzles, and Knight is “Mordred” in current Independent puzzles."

The list author says:
	"Again one which I don’t own but I believe does a sound job."

The list author says:
	"Possibly aimed at solvers in South Africa - I haven't seen a copy."

The list author says:
	"Reissue of a guide written in 1989.  OK but a bit outdated."

The list author says:
	"A decent guide written by a solver - example puzzles and clues aren't so good."

The list author says:
	"Recent (2009) book by expert clue-writer Colin Dexter.  Short and quite useful, but could have been a lot better."

The list author says:
	"I don't have this one, but MCC Rich, who wrote the introduction, knew his cryptic crosswords well enough to edit the Listener puzzle so is unlikely to have contributed to a bad book."

The list author says:
	"I don't own this but its sole Amazon reviewer likes it."

The list author says:
	"Of the ones I own, this is the least helpful - see my review for the reasons."
