This work of experimental thesis considers an actual reality that concerns, from a few years, with the process of scientific communication: Open Archives and the OAI initiative (Open Archive Initiative).
The interest for such matter has sprung from the reading of an article, published on the News-bulletin of the SIMAI (Italian Society of Applied and Industrial Mathematics) by Dott.ssa Antonella De Robbio, Responsible of the library of the CAB (Center of athenaeum for libraries) beside the University of the Studies in Padua, in which some open problems were underlined related to the communication of the research results inside the academic scientific community.
Particularly this thesis focuses the attention on the OAI protocol for the metadata harvesting developed by the same organization.
Are so evidentiated technical aspects related to the computer communication through the web, giving particular importance to the Data Provider subject, that is the active actor in such communicative process.
Another important treated aspect is made up of OAI-Rights: internal initiative of the same OAI, which investigates on a new reality that is the guardianship of the intellectual ownership right regarding the bibliografical metadata.
The experimental part of this work consists in the application of the CDSware software (Cern Document Server Software) for the web representation of bibliographical records imported by the library managerial system Aleph 500. 
Particularly, the realization of such part is focused on the use of a CDSware internal module: BibFormat, that allows the creation of representation formats related to bibliographical data stored in the system for the end user.
