No -- in some cases I have even more copies of a given archery title. It depends on how interesting and special I think book is. Folks collect multiple Bear bows, e.g., and some folks have a number of the Bear knife, file and stone kits [I only have one of each of these].
E.g., I have a number of copies of Klopsteg's first edition of "Turkish Archery" [1934] that was limited to 100 copies. I thought that it was a seminal work on Turkish Archery, and I especially like the red quarter leather and gray cloth binding.
We're all motivated a little differently.
Bofari is definitely a collector's book.
