Undergraduate students are usually the largest populations in higher education institutions. More information about qualitative aspects of learning practices and deeper knowledge about student needs is necessary to understand and promote a more implicated role of libraries in undergraduate student learning. The project reported at this poster is developed by researchers from two private universities libraries in Mexico. The research methodology used is mixed. After analysis and discussion of initial data some student’s characteristics were established as diversity markers which we expect will facilitate to select students for deep interview in order to listen the variety of undergraduate voices and analyze them to guide the design of new library spaces, collections and services We expect also that the methodology developed will help to select participants from other library user groups from a diversity perspective.
