If it's general English guns then trw999 has it spot on but I would also add The British Sporting Gun & Rifle by Donald Dallas.
Saskbooknut also mentions one that is a 'must have'. Even if you get just one book then this should be it; even though the last and 9th. edition goes back to 1910 it is a great reference work and a great read too. Lagopus.....
I couldn't disagree more with my English Brethren, The BEST book to read is the one written by Cumming, 'A Hunter's Life in South Africa'
After reading that book then start your library.
