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 $45 US for USA and Canada, $55 US 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 (i.e. a (subscribed) museum or university may make as many copies as needed in whatever format desired).
