The DDC and OCLC

ABSTRACT

This article highlights key events in the relationship between OCLC Online Computer Library Center, Inc. and the Dewey Decimal Classification (DDC) system. The formal relationship started with OCLC's acquisition of Forest Press and the rights to the DDC from the Lake Placid Education Foundation in 1988, but OCLC's research interests in the DDC predated that acquisition and have remained strong during the relationship. Under OCLC's leadership, the DDC's value proposition has been enhanced by the continuous updating of the system itself, development of interoperable translations, mappings to other schemes, and new forms of representation of the underlying data. The amount of categorized content associated with the system in WorldCat and elsewhere has grown, as has worldwide use of the system. Emerging technologies are creating new opportunities for publishing, linking, and sharing DDC data.

OCLC近况

<正> 著名的OCLC原是1967年由54个俄亥俄学院和大学图书馆组成的计算机化的地区性合作网络(Ohio College Library Center),由于它的成功发展,参加馆从大专院校图书馆迅速扩展至公共图书馆等各种类型的图书馆,在地区上也从俄亥俄州扩展至全美国乃至世界其它一些国家。因而于1981年改名为“联机计算机图书馆中心公司”(OnlineComputer Library Center,Inc)。OCLC是当前世界上最大的图书馆情报网络,建立了庞大的书目数据库和把26个国家的图书馆连接起来的计算机化网络,为图书馆界和其它教     

The OCLC online union catalog: An incomparable library resource

Furthering access to the world's information and reducing information costs are the major goals of Online Computer Library Center, (OCLC) a nonprofit library computer service and research organization based in Dublin, Ohio. OCLC pioneered the computer revolution in libraries in 1971 when it introduced a computer system that enabled libraries to catalog books and order custom-printed catalog cards rapidly and efficiently. Today, OCLC provides a spectrum of services for libraries and their users. OCLC systems in cataloging, interlibrary loan, document delivery, reference, and electronic publishing provide an integrated approach to navigating the sea of knowledge for libraries and their users.     

The OhioLINK OCLC Collection Analysis Project: A Preliminary Report

The article will describe the plans and work to date on the OCLC Research Office and OhioLINK's joint project to analyze use data from Ohio college and university libraries. The project will create a repository of data about the circulation of monographs that can be correlated against such data points as subject, age of material, location and publisher. One of the goals of the study is to investigate whether there has been a shift in the general patterns of use of library collections in a situation where libraries have instituted patron-initiated borrowing from one another. The project is similar to a study that the OCLC Research Office did with the University of Colorado, Boulder, but on a larger scale and with the addition of information about monographs that do not circulate. An article about that study appeared in the January 2006 issue of College and Research Libraries.     

RLG and OCLC: Combined for the Future

On July 1, 2006, The Research Libraries Group, Inc. (RLG) and the Online Computer Library System (OCLC) combined their organizations and resources. RLG's products and services were integrated with OCLC's, and RLG's program initiatives went forward within an expanded OCLC Research division. This was a historic moment for libraries and research institutions consonant with the incredible changes in the information environment that had been underway during the previous decade. The expansion of WorldCat that resulted and the renewed attention given to research libraries by OCLC in the merger has positively impacted libraries around the globe.

The PCC and OCLC: Some Reflections on 45 Years of Cooperation

Abstract

The OCLC Network of Regional Service Providers: The Last 10 Years

Developed in the early 1970s, the alliance between the Online Computer Library Center (OCLC) and its regional service providers is a strategic partnership that has survived for over 30 years. Originally created by OCLC to help it efficiently reach out to libraries in other states beyond its initial Ohio focus, this alliance is now starting to transform into a new structure. This new structure as well as other changes in the relationship between OCLC and its partners will have an impact upon all of the organizations involved.     

OCLC术语服务研究：背景、进展与启示

OCLC术语服务是互操作领域的一个研究项目。术语服务可以理解为涉及各种类型知识组织资源(包括规范文档、主题词表系统、网络分类、分类表等)的Web服务。该项目的目标是通过在多个受控词表之间有选择地建立映射,帮助文献收藏机构为馆藏创建相互兼容的元数据,通过任何基于网络的元数据编辑器获取术语资源,实现对术语资源的一站式获取。我们可以借鉴OCLC的做法,对国内外词表问映射进行研究。表4。参考文献3。
