Library as a provider of information should meet the needs of diverse users. However, basically library is not able to collect the information that has been produced by scientists on earth, so it has become a major concern for information workers.Responding to the problem, library so far has done the effort to fill the needs by making cooperation with other libraries or other information providers. The model of the cooperation has also evolved and been adapted with the development of the information and communication technology.Library in each university in the region of Yogyakarta also has made cooperation and library network such as, FPPTI DIY stands for (Forum Perpustakaan Perguruan Tinggi Daerah Istimewa Yogyakarta) Forum of University Libraries in Special Region of Yogyakarta which is a form of cooperation among university libraries or private university libraries producing the main catalog named JLA (Jogja Library for All) as a part of the library cooperation. JLA which has been working for 12 years apparently has minimal utilization, because visitors can only see a list of catalogs and can only use the existing room facilities without being able to borrow the collection. While in Ohio which is a state of the United States, there is also a very good cooperation both in terms of systems, content and resources. As well as cooperation carried out by FPPTI which produces the main catalog website, cooperation in Ohio also produces a website, but not just a main catalog. This paper will explore the extent of the cooperation in JLA in terms of its problems or obstacles and benefits for librarians, when compared with the cooperation in OHIO Link.
