During the past three years, from terminals within Beth Israel Hospital, Boston, 3,654 persons used a computer program called PaperChase to search the medical literature. While performing 39,022 searches, these persons had 1,976,421 references displayed and selected 449,690 of them for printing. Throughout this period, the program underwent continual modification. Each year the number of searches increased--from 10,678 to 11,541 to 16,803. Each year the percentage of new users who were unsuccessful decreased--from 16 to 13 to 11. By the end of the third year, 549 people had completed 20 or more searches. PaperChase enables people to search the medical literature themselves, and thus provides a new experience in computerized bibliographic retrieval. When made available without charge in a teaching hospital, PaperChase is widely used.
在过去三年里，来自波士顿贝斯以色列医院各终端的3654人使用了一个名为“文献追踪”的计算机程序来检索医学文献。在进行39022次检索时，这些人共显示了1976421条参考文献，并从中选择了449690条进行打印。在这一期间，该程序不断进行修改。每年的检索次数都在增加——从10678次增加到11541次，再增加到16803次。每年新用户检索未成功的比例都在下降——从16%降至13%，再降至11%。到第三年末，有549人完成了20次或更多的检索。“文献追踪”使人们能够自行检索医学文献，从而在计算机化文献检索方面提供了一种全新体验。当在教学医院免费提供使用时，“文献追踪”得到了广泛应用。
