I can recall stumbling upon The Universal Bead by Joan Mowat Erikson, 1969 on a Library shelf. By then I had been collecting millefiori and Chinese sewing basket beads, and odd beads of interest found here and there and anywhere I could. I need to find an Old copy- and look it over with today's eyes. I see that Abe Books sells copies and newer editions (the original edition cover photo of Trade Beads is most interesting IMO).
