I see that the URLs for the two sites I mentioned did not copy into the posted version.

To access the two indexes, visit the Society of Bead Researchers site and click on the Our Publications drop-down menu. https://beadresearch.org/our-publications/beads-index/

For the Bibliography, click on the Resources drop-down menu. https://beadresearch.org/resources/researching-the-worlds-beads-bibliography/
