资源共享群组
图书馆集团和联盟可通过 WorldShare 馆际互借实现高效经济的馆藏合并。设置非常简单，尤其当参与者已经是 OCLC 的成员机构时。集团内图书馆可轻松向 WorldCat 贡献馆藏资料，所以它们对 WorldCat 搜索者可见。
集团检索功能 (GAC) 组织是按主题、地理位置或其他属性联合在一起的特设图书馆协会，也可使用 WorldShare 馆际互借。所有成员均可访问各自的书目、位置和摘要馆藏记录。这些团体中最大的组织是 Libraries Very Interested in Sharing (LVIS)。
这里是OCLC组接入能力（GAC）和联合目录（UL）异形组的列表。对于每个组内成员机构的符号列表，请参阅OCLC策略目录。
