Okay, if Tim won't mention it, I will:  Carolyn White's book with AltaMira
Press, *A Guide to the Artifacts of Personal Adornment*, has a pretty
comprehensive button section that updates Hinks and certainly South and Noël
Hume's button material.  I may have the title wrong; my copy is in my lab at
BU & the uni is closed down on intercession just now.

(Everyone please remember that the INH *Guide* has never been revised since
its first appearance in 1969, and, as a result, is scarcely reliable
anymore, apart from a general introduction to certain classes of
material—but I would not consider *anything* in it as definitive without
first checking other sources!)

As Tim makes clear, there is plenty of room for up-to-date studies of
material culture and Tim and Carolyn's series provides a venue with an
affordable and amiable press.  It would be a wonderful thing for
button-knowledgeable folks out there to work up a comprehensive guide to
buttons for archaeologists, vs. collectors!

Cheers & happy new year!
