Library services are essential for teaching. Therefore a LMS redesign concept should guarantee better integration of library services like catalogs, databases and media as well as literature and information management. A comparision to other industries can be helpful: often customer relationship is maintained and intensified by using customer accounts; especially customer accounts of banking systems and insurance companies should be considered. Online banking accounts offer a large number of relevant customer relationship functions that could be helpful in library management systems, too. Also involving librarian professionals in literature researches can be useful.
