Abstract: The Automated Literature Alerting System (ALAS) was developed at Eli Lilly and Company and implemented in January 1967 as a successor to the Chemical Titles tape program. The magnetic tapes received weekly from the Institute for Scientific Information contain title information from about 1800 journals which produce an average of 5600 article titles per week. However, during processing, about 600 non‐pertinent journals are deleted. The program began with an initial group of 58 CT subscribers, and new users are continually being added. Each user has been receiving from 0 to 400 citation cards per week, depending upon his profile of key words. The median is about 70 to 80. The system consists of eleven programs for profile and key word generation and maintenance, indexing, searching, and printing, and uses an average of 3.2 hours of machine time a week on an IBM S/360 F30. With 82 users currently in the system, this amounts to about 2.3 minutes of computer time per user per week. Searching is based on a key word system which allows the use of words, authors, prefixes, and suffixes, and employs AND, OR, and NOT logic.
