Libraries are discovering new and original ways of acquiring resources for their electronic, physical, and digital collections to suit the changing needs of users. Acquisition models need to be flexible, dynamic and fast to meet their expectations. Ex Libris Alma was designed to enable each library to adopt the acquisition models that best address their staff and users’ needs while also supporting collaborative approaches. In this session, we will review the various acquisition models that are being used by academic and research libraries, with a particular focus on e-resources, and we will discuss ways that Alma supports these diverse models.
