Please use your ISTR account credentials to login.
If don’t have an ISTR account, you can become a member (see 2-year rates here https://www.istr.org/page/Membership). Membership is not required to submit an abstract but we encourage you to join now.
Expired members, please consider renewing by clicking on the "join/renew" button in the top right hand corner of our website www.istr.org. Expired members will not be able to log in as guests and will need to contact ISTR to convert their accounts to guest memberships. Renewing is the better option if possible.
You may also sign in with a Guest Non-Member account, but you must contact ISTR to make this arrangement (too many spam/fake accounts were being created when we opened it to the public). If you need help creating an account or converting your membership to one that will let you log in please contact the Secretariat at Secretariat@istr.org.
