摘要

本研究主要探討OPAC文獻之基本特性，如：文獻成長情形及出版品類型、語言、作者與期刊之分布情形，並以書目計量學之洛卡定律和布萊德福定律，加以驗證著者生產力與期刊文獻之分佈。研究結果發現1975至2000年間，OPAC文獻仍持續的成長，呈現邏輯斯第曲線的成長模式；文獻發表的語言以英語為最普遍，並且以強調新穎性的期刊類型為主要出版品；出版一篇文獻的作者佔77.82%；利用布萊德福定律求出八種核心期刊。在文獻作者生產力與期刊文獻分佈方面符合洛卡定律與布萊德福定律之結果。

On the basis of bibliometric analysis, this study explores the characteristics of the OPAC literature, such as the literature growth, document type, language, author productivity and the distribution of journal articles. The OPAC literature, 1975-2000, mows an example of logistic growth. English is the predominant language and the most popular form of publication is the journal article. The vast majority of authors, (77.82%), publish one article only in the subject of OPAC. Eight core journals were identified based on Bradford's law. The results of the present study also revealed that author and journal productivity were consistent with Lotka's law and Bradford's law.
