隨著資訊科技的進步與網際網路的普及，電子資源越來越受到重視，各類型圖書館也多朝數位圖書館的方向發展，因此圖書館有了「為資訊建立檢索點，並為使用者提供服務的機構」這個符合資訊時代的新定義；而理想的數位圖書館，不只是電子資源的彙積，更應該是個具備專業的服務人員與精選的電子資源，並為特定使用者社群提供便利且具經濟效益的服務組織。臺北醫學大學數位圖書館聯盟（簡稱TMUDiLib），就是在前TMU DiLib），就是在前），就是在前述兩個理念下，結合中小型醫院圖書室之資源與能量所組成的合作網。本文首先簡述臺灣地區現有的醫學圖書館聯盟之概況，之後詳細說明TMUTMU DiLib聯盟的現況、服務成果與發展，期望提供各類數位圖書館聯盟在建聯盟的現況、服務成果與發展，期望提供各類數位圖書館聯盟在建置與推廣時之參考。

Nowadays, libraries pay much attention to electronic resources because of the advancement of information technologies and the wide spreading of the internet connections. Libraries in different types are evolving toward the direction of digital libraries. As a result, a new definition of a modern library is proposed – a library is an institution to establish access points of information and to provide services for its users. In the meantime, an ideal digital library should not only be the accumulation of electronic resources, but also an organization provides the resources including the specialized staff and qualified collections of digital works; therefore, they are readily and economically available for use by a defined community or set of communities. Based on the above ideas and cooperating the resources and powers of small and middle size hospital libraries, the Taipei Medical University Digital Library Consortium (TMU DiLib) was founded. To begin with, this article briefly introduces five major medical library consortia in Taiwan, and then describes the current status, service performance, and future development of the TMU DiLib consortium. The author hopes to serve as a reference for establishment and promotion of other digital library consortia.
