The Taxonomic Report (TTR) is the main scientific publication of the International Lepidoptera Survey (TILS). TILS-TTR is currently on hiatus but formerly was published at the rate of 8–10 issues a year. Subscription / dues are usually US $45 for USA and Canada, US $55 for overseas subscribers. At the end of each volume year, subscribers receive that year's volume on a read-only compact disc for archiving and reproduction for personal use (that is, a (subscribed) museum or university may make as many copies as needed in whatever format desired). Non-members may receive individual issues in print any time for $10 per issue. Individual issues on CDR to non-members are $25 per issue post paid. Subscriptions and individual issue orders should be made payable to TILS and checks mailed to: Harry Pavulaan, TILS Editor, PO Box 1124, Herndon, Virginia 20172 United States.
