Abstract: BRAC University library (BRACU library) implemented a number of projects using open source software DSpace, Koha, VuFind, and Drupal, and several initiatives to meet the demand of the changing needs of teaching, learning, and research communities. This paper provides a summary of our experiences that focus on some of the key issues we have had to consider, the choices we made and the challenges we addressed during the implementation of the library technologies, and finally setting up a next-generation library. This paper also describes how BRACU library helps to build capacities of library professionals and assists other universities in Bangladesh embarking on similar projects.
