The reference staff of the Washington University School of Medicine Library, in an attempt to consider an alternative way of providing the information contained in the printed Chemical Abstracts, designed a study to examine whether the on-line version of Chemical Abstracts could be substituted for the hard copy. For a thirteen-week period, all patrons using the printed index were offered a free computer search of Chemical Abstracts in exchange for evaluating the searches. Only 39.6% of those offered a free search chose to do so. Of these patrons, 62% still planned to refer to the abstracts later, which are only available in the printed index. The hypothesis that the on-line version could be substituted for the printed index was not confirmed.
华盛顿大学医学院图书馆的参考馆员试图考虑一种替代方式来提供印刷版《化学文摘》中包含的信息，于是设计了一项研究，以检验《化学文摘》的在线版本是否可以替代印刷版。在为期13周的时间里，所有使用印刷索引的读者都可以免费进行《化学文摘》的计算机检索，以换取对检索的评估。提供免费检索的读者中只有39.6%选择这样做。在这些读者中，62%的人仍计划稍后查阅仅在印刷索引中提供的文摘。在线版本可以替代印刷索引的假设未得到证实。
