The first comprehensive system that organizes pharmaceutical and biological information for veterinarians on microfiche has been introduced by Anacomp, Inc., a leading information data base systems developer. The program, called Animal Health Information System (AHIS), is based on the continually updated drug formulary prepared by the College of Veterinary Medicine at Cornell University, which includes current research, clinicians' experience, journal articles, texts, handbooks, and manufacturer's information, for a total of 26 sources in all.
