One of my real favorites on the topic of archery is the Traditional Bowyer's Bible series, particularly the first volume. In the first volume is a great article on western Indian arrows.
Note that these books are really for people who want to make traditional bows and arrows, not collectors. They won't directly help you authenticate a piece. They will help you determine whether the arrow is authentic in the sense that it would fly straight, what use it was designed for (like the skipping arrows used for hunting waterfowl in the western US), etc. The first volume in particular focuses on native american bows and arrows, but subsequent volumes talk about archery on other continents.
Also, these should be available from Amazon.
