HAVE YOU TRIED SINGLE SEARCH? With the information explosion, the literature in any subject is increasing not only in volume but also in variety. Today, a typical library has to manage the following information sources: library physical holdings, digital repository, electronic journals, web and other e‐resources. Each of these resources has different web interface, making it difficult to a user to learn all of the interfaces and also time consuming to search a particular information. By offering a one-stop resource that allows the patron access to all of the library’s materials from one place, the library can truly begin to leverage its resources and deliver them to its users more effectively. Discovery tools make it possible to search multiple resources with one query. THAT’S WHY WE HAVE SINGLE SEARCH!
