Abstract
The primary objective of any objective-based resource retrieval system is to provide users with a rapid, cost/effective means of retrieving resources suited to the needs of the learners. This is accomplished by Battelle's BETSY system through the use of a computerized retrieval system designed specifically for educators to facilitate learning.
BETSY began as an idea during the summer of 1973. Its roots can be vaguely traced to the Computer Based Resource Units (CBRU) of Buffalo, New York. The original premise was to make CBRU available on-line to educators. Through an ESEA Title III grant to the Mentor, Ohio Board of Education, this original concept was stretched and expanded to the present system that not only provides on-line access to over 15,000,000 characters of data, but also provides a very low cost planning instrument. What was originally student oriented is now learner oriented. That learner can still be a student, but he can also be a teacher or curriculum designer.
