Established in 2003, e-LIS is an internationaldigital repository for Library and Information Science (LIS). It has grown to include a team of volunteer editors and support for 22 languages. The development of an international LIS network has been stimulated by the extension of the Open Access concept to LIS works and facilitated by the dissemination of material within the LIS community. These are some of the reasons for the success of e-LIS.
In a few years, e-LIS has been established as the largest international open repository in the field of library and information science.
