Purpose The paper seeks to describe the setting up of the Energy and Resources Institute TERI Digital library, which provides better single window access for researchers to access the structured information from their desktop. The aim of this paper is to share the experience gained and invite comments and suggestions for further improvement. Designmethodologyapproach The paper describes a case study of TERI's Integrated Digital Library resources and digitization in detail and how the digital resources can be accessed through a single window. It also deals with basic problems and suggests practical solutions. Findings The paper finds that TERI Integrated Digital Library has been created to provide access to all digital and digitized offline and online resources, online ejournals, electronic documents and virtual resources, and virtual libraries. The purpose of the integrated library is to provide a single window to researchers, through which they can access all the resources both digitally born resources and digitized documents. Once users are able to access the Digital Library homepage, all the electronic resources are accessible using linkages with a single click, no matter whether they are available in a database or as a simple file in a virtual collection. A physical digital library has been created to address access to all the LAN connected systems that provide CDROM access and journals and books downloaded or purchased for all time free access to inhouse users. Research limitationsimplications Integration has helped in saving researchers' valuable time. Library management has become easier and much more effective than was previously the case. Any additions to existing resources are announced by email for user access. Future plans are to make the resources highly interoperable across platforms or applications, so that platforms should not be a problem. Once a search is initiated, the search engine from the main search window should be able to hand over the search to subsequent search windows for any given database bibliographic and full text. Once a search is handed over to the subordinate search engines, it should be able to retrieve the items and display the retrieved items in the main window. Future libraries seem to have no escape from the integrated digital library approach other than to an integrated digital collection that will make all available resources accessible from a single window. Originalityvalue This paper could be useful for small and medium special and research libraries who do not have enough funds to start with commercially available digital library software. This paper shows the way to start using Open Source Software, which is easy to use and has been used by the libraries with little effort.
