许可

DDC 系统已有超过 135 年的历史,因此,很容易让人以为 Dewey 这一名称早已存在于公共领域中。然而,并非如此,直至 1988 年,OCLC 联机计算机图书馆中心 (OCLC Online Computer Library Center) 才拥有 Dewey 名称的商标权。

如果您对将 Dewey 名称或分类号用于合法商业用途的许可感兴趣,请首先联系 busdev@oclc.org。我们制订了在保护 OCLC 商标权的前提下,允许其他机构使用 Dewey 名称的许可协议。

杜威十进分类法 (DDC) 系统是全世界使用范围最广的图书馆馆藏整理方法。DDC 会持续进行更新,从而使相关主题在所有语言中都能更容易地被人们发现。由于 DDC 的使用十分方便,因此您可以快速高效地增加资料的可见性。
