University Institutional Repositories: an analytical study of the ten best university Repositories
The research aimed to study and analyze the best global University institutional repositories, which were selected by the search engines and the Spanish website Metrix. A descriptive approach has been used to carry out the research (survey) and a deliberate sample has been taken (ten university repositories) from a community of 500 repositories mentioned in the directory of free access repositories (open Dora), in terms of content, types of digital content management systems, number of recordings, language used and methods of storage and retrieval. The study found that 70% of university institutional repositories used the open source Dspace system. Press articles have been ranked first with a percentage of 100%, while theses came in second rank with regard to the substantive content of the repositories. Moreover, it is found that the position of the repository does not depend on the number of existing recordings as much as it depends on the quality, usage and the links of these recordings.
