CHEMLINE (CHEMical Dictionary OnLINE), the National Library of Medicine's online chemical dictionary file, is primarily used by librarians and information scientists to enhance the retrieval of bibliographic information associated with chemical substances. This paper will discuss CHEMLEARN, a microcomputer-based training program designed to provide inexpensive, easily accessible self-instruction as an alternative to formal classroom training in the use of CHEMLINE. CHEMLEARN allows novice users to learn at their own pace and with considerable program feedback. In addition, it provides the skilled searcher with a way to reinforce or recall previously learned search techniques without incurring online charges. CHEMLEARN may be used in place of formal training or as a precursor to or a refresher following formal training.
CHEMLINE（在线化学词典）是美国国立医学图书馆的在线化学词典文件，主要供图书馆员和信息科学家使用，以加强与化学物质相关的书目信息检索。本文将讨论CHEMLEARN，这是一个基于微型计算机的培训程序，旨在提供低成本、易于获取的自学方式，作为使用CHEMLINE进行正规课堂培训的替代方案。CHEMLEARN允许新手用户按照自己的节奏学习，并能获得大量的程序反馈。此外，它为熟练的检索者提供了一种方法，可强化或回忆以前学过的检索技术，而无需支付在线费用。CHEMLEARN可用于代替正规培训，或作为正规培训之前的预习或之后的复习。
