It's a good start.
Numerous titles on numerous topics have been recommended both here, on the 'Colt Forum' as well as in the 'Historical Society Forum'.
Matter of fact, you can pretty much pick your topic of research, and someone's done a book (or books) on it, and someone has already given it a review, so in that light, you're set.
Stay away from the terms: 'I read it once...' - 'I seem to remember...' - 'Somebody told me...' - 'A guy at the gun shop said...' and my all-time, personal favorite - 'I saw in this movie...' - a sub-set of which is - 'If it's good enough for the Duke...'.
None of these comments have any validity whatsoever, and the 'John Ford Reference Library' has done more to cloud the true history of the Old West than any other method - purposely choosing people, places, manner of dress, tribes, and weapons so completely out of place that it's ludicrous.
With reference books, the writer has to research and has to cite sources, so there's validity and bibliographies at your fingertips, should you want to dig deeper.
One of the big problems is that these are getting ever more expensive, so keep your eyes open, because when some of these titles hit the secondary market, their prices went up ten-fold.
Vaya,
Scouts Out!
