Membership of the ISDR is open to all.  Members receive the international journal, Diatom Research, which from 2011 has been published by Taylor and Francis twice yearly on current topics of diatom study.  Almost all papers are in English but we also publish in French, Spanish and German.  Please encourage the diatomists with whom you have contact to join the Society and publish in the Journal.

The Society holds its International Symposium at a different venue, every two years and is open to all interested persons but it includes the general meeting of the Society’s members.  Paid-up members are entitled to a discounted registration fee.  The International Symposium produces its own series of highly topical and properly refereed papers.

The Society is registered as a charity in the UK (No. 1054897) which helps to keep the subscriptions as low as possible.  It also seeks support for some persons otherwise unable to attend the International Diatom Meeting.
