The International Association for Obsidian Studies (IAOS) was formed in 1989 to provide a forum for obsidian researchers throughout the world.

You can apply for IAOS membership in one of three categories:
Student members are those who are currently enrolled as a full or part-time student. Student benefits are the same as those of regular members.
Regular members are individuals or institutions who are interested in obsidian studies and who support the overall objectives of the IAOS. Regular members will receive the regular IAOS Bulletin, general mailings, announcements of meetings and conferences, and any software or papers that are distributed by the IAOS for the year. Regular members are entitled to attend and vote in the Annual Meeting.
Institutional members are those individuals, facilities, libraries, and institutions who are active in obsidian studies and who wish to participate in interlaboratory comparisons and standardization. Institutional members may receive assistance from, or collaborate with, other institutional members. They will also receive all other mailings sent to regular members.
Lifetime members receive all the benefits and privileges of Regular Members, but in perpetuum, for as long as they or the IAOS shall last.
Membership fees may be reduced and/or waived in cases of financial hardship or difficulty in paying in foreign currency. Please complete the form and return to the Secretary with a short explanation regarding the lack of payment.
Because membership fees are very low, the IAOS asks that all payments be made in U. S. dollars in international money orders or checks payable to a bank with a U. S. branch. Domestic or international payments may now be made through PayPal.
