INTERFACES Y FUNCIONALIDADES DE BIBLIOTECAS DIGITALES.

Literature on evaluation of digital libraries is reviewed, emphasizing the complexity of the processes and the diversity of methodologies. This work proposes an analytical approach to the basic characteristics of the interfaces in a sample of digital libraries by means of parameters and criteria that allow observing its implementation and possible translation towards formalized tools for the participation of real users and experts in the evaluation. Future lines of work are suggested. [ABSTRACT FROM AUTHOR]
