馆际互借是资源共享的一种形式。有些时候,读者的借阅需求不是一个图书馆所能全部达到的,因此,图书馆之间便产生了资源共享的需要。计算机能够对这种馆际之间的需要进行管理,这就是馆际互借系统。馆际互借系统的建立必须具备两个条件:一个是运行的计算机借阅系统,另一个是完善的计算机通信网络。所有参加馆际互借的图书馆,都必须具备这两个条件,同时也必须加入网络之中,成为馆际互借系统中的一个 Interlibrary loan is a form of resource sharing. In some cases, the reader’s borrowing needs are not all that a library can achieve, so there is a need for resource sharing between libraries. Computers can manage the need for this kind of intercourse, which is the interlibrary loan system. The establishment of interlibrary loan system must have two conditions: one is to run a computer loan system, and the other is a perfect computer communication network. All libraries participating in interlibrary loans must have both of these conditions and must also join the network to become one of the interlibrary loan systems
