Research institutions need to publish the results of their investigation work and submit for review to their peers.
Preprints and postprints are research result documents produced respectively before and after peer review. Both are known collectively as eprints.
There are repositories accessible through the Web that store eprints metadata, i.e. information that describe details of the eprints.
This class provides means to access eprints repositories and retrieve the available metadata. It can be useful to researchers that are looking for eprints relevant to their work.
