Karlis Karklins, Society of Bead Researchers.
Updated August 25, 2013.
This bibliography is aimed at worldwide coverage in bead research, and is divided into 9 sub-sections (available as web .pdfs), most of them geographical (including Europe/Mediterranean, Middle East, Africa, etc.) but also technological (Archaeometry, Technical Aspects). Within each subsection citations are organized alphabetically by author and include books and articles in multiple languages. Most items date from 1985 to present, and there is a focus on beads from archaeological contexts. The compiler welcomes additional citations by email.
