To encourage anybody interested in protists to join ISOP and discover the benefits of belonging to our dynamic organization, ISOP has approved two special offers for any NEW member:

1) A free copy of the Illustrated Guide to Protozoa (2nd edition) to any new member who joins at the regular rates (while supplies last; member must pay for shipping - $11.95 in the USA; $27.95 in Canada and Mexico, $45.95 elsewhere). To claim this offer, contact Michael Dolan (


2) Free trial membership. The one-year trial membership includes full on-line access to the journal and other society publications, and eligibility for travel grants and awards. It does not include other benefits such as discounts on meetings or page charges, or the free copy of IG2.

Regular Membership is open to anyone with an interest in protozoa and related protists. Regular members have all usual privileges of membership and receive The Journal of Eukaryotic Microbiology, the Newsletter and Abstracts of Annual Meetings of the Society of Protozoologists.

Student Membership is available to students upon certification of student status by a member, or the Department Chairperson. Student members have the privileges of regular members.
