I'm planning to replace my Bradford's Crossword Solver - it's (gulp) 30 years old!
Has anyone used the Kindle version? Is it easy to look things up? As easy as the old-fashioned way.
Chambers Crossword Lists paperback; unlike other list books, what you want is listed alphabetically, not by category, e.g. rivers is under R and not a sub-category under geography. Longman Crossword Key, hardback, I also find useful. Electronic device I like is Oxford Crossword Solver ER3500 which has sensibly-sized keys and a good screen, with lots of lists and features. Hope this is helpful.
