  The vehicles for official knowledge, as well as university libraries, suffer
from an increasingly visible lack of interest. This is due to the advent of
fully digital practices. By studying the psychological and cognitive models in
information retrieval initiated in the 1980s, it is possible to use these
theories and apply them practically to the Information Retrieval System, taking
into account the requirements of virtual libraries. New metadata standards
along with modern tools that help managing references should help automating
the process of scientific research. We offer a practical implementation of the
given theories to test them when they are applied to the information retrieval
in computer sciences. This case under study will highlight good practices in
gleaning and harvesting scientific literature.
