TRANSPARENT RANKING: OA repositories and portals in TURKEY by Google Scholar

TRANSPARENT RANKING: OA repositories and portals in TURKEY by Google Scholar (March 2022)

          During the last months, we realized the indexing of records of several open access repositories by Google Scholar is not as complete as previously without a clear reason. From the experience of a few cases, it looks that GS penalizes error in the metadata descriptions, so it is important to the affected repositories to check their level of indexing and to try to identify potential problems.

          Please, consider the following Indexing GS guidelines
          https://scholar.google.com/intl/en/scholar/inclusion.html
          https://www.or2015.net/wp-content/uploads/2015/06/or-2015-anurag-google-scholar.pdf

          and the following material: Exposing Repository Content to Google Scholar

          A few suggestions for improving the web visibility of the contents of your institutional OA repository
          "Altmetrics of the Open Access Institutional Repositories: A Webometrics Approach"

          As a service for the OA community in Turkey we are providing a combined list of repositories (institutional, subject and portals) with the raw numbers of records in GS for their web domains (site:xxx.yyy.zz excluding citations and patents) ranked by decreasing number of items. The list is still incomplete as we are still adding new repositories.

          As usual, you can contact our editor (Isidro F. Aguillo) for any comment or suggestion.

This ranking has been funded by the CSIC Intramural 201710E077
