中國圖書分類法

「中國圖書分類法」為編目人員分類時之重要工具書，隨著科技的進步、出版品的激增，賴永祥編訂之「中國圖書分類法」（增訂七版）已不能滿足分類的需求，因而衍生出一些實際編目問題，這些問題包括：（1）電腦類類號不詳盡（2）分類編排不一致（3）類號過於簡略（4）年代問題（5）著名人物問題（6）新主題無適當類號可歸（7）類目標題用詞未臻理想（8）一主題，雙類號等。除探討上述問題外，對於一個良好的分類法所必須具備的基本要件也加以闡述，並提出相關建議，希望對將來再版之分類表修訂有所幫助，以解決部份編目上之問題。

The New Classification Scheme for Chinese Libraries (7th ed., edited by Yung-hsiang Lai) has been an important reference tool for catalogers. However, with the advent of new technologies, publications increase in number and speed, and have overwhelmed the traditional cataloging system. This classification scheme has become obsolete and no longer effectively meets a cataloger’s needs. The purpose of this article is to discuss the discrepancies in this classification scheme and its problems. Listed below are topics of interests 1) Unclear numerical designations in the computer 2) Inconsistent subdivisions of categories 3) Over-simplified numerical designations 4) The problems of classifying by year of publication 5) Problems with famous authors 6) Unsuitable classification for new subjects 7) Unsuitable subject descriptions in cataloging 8) Duplicated designation the same subject etc. The basic requirements of a good classification scheme are also described in this article. Several suggestions are given at the end in the hope that the next edition of New Classification Scheme for Chinese Libraries would be more robust and effective for cataloging publications in the 21st century.

分類檢索是網路書店提供的重要查詢功能之一，由於每家使用的分類法皆不一樣，所以使得很多相同主題的書卻放在不同的類目下，造成民眾在連結兩家以上的網路書店後，進行查詢時會產生選用類目的困擾。本文認為我國網路書店可仿效圖書館界，使用中國圖書分類法做為相關檢索點採用的標準，再配合預行編目(CIP)的分類資料，即能達到一致性的查詢介面，增進民眾使用分類檢索的精確率。而網路書店的經營者在網路購書行為日益增多的環境中，實應主動整合目前各行其是的分類法，才能掌握更好的發展機會。

Classification schemes have served as one of the major searching functions of the online bookstore. However, because there are quite a few classification schemes being used among online bookstores, books of the same field are likely to be placed under different subject headings in different online bookstores. Consequently the searcher may have difficulties in selecting subject headings if he uses more than one online bookstore. The author suggests that local online bookstores may use the New Classification Scheme for Chinese Libraries as the source for search keys. Together with the use of the CIP classification data, search interfaces can, in this way, be more coherent and the accuracy in subject searching raised. Managers of online bookstores should aggressively integrate the various classification schemes being used in order to improve the service of the industry as a whole.
