Just thought I'd bring to everyones attention the July 09 issue of Book and Magazine Collector. It contains a seventeen page article written by Ben Bridges (David Whitehead) about his choices of the top 50 westerns books, with information about many of them, including how much they are worth. It makes for fascinating reading.
Amoung the other articles is an in-depth look at the work of Cormac McCarthy.
The magazine can be found in UK shops now - not sure about other countries, but it can also be ordered direct.
