The Ranking Web of Repositories – A great tool for finding OA materials
Green Open Access is now the most popular way to publish scientific papers at no cost. The number of repositories worldwide is huge, and it is sometimes difficult to even determine how many of them have been launched. Institutions, foundations, universities – all are interested in launching repositories for OA articles. However, not all of these repositories contain valuable scientific materials. So, how does one find a repository that is rich in content? This tool can make this job easier.
The Ranking Web of Repositories is a unique website which does exactly what it says. It categorizes repositories by region and country of origin. Users can narrow down their searches to a specific region, for example: North America, Latin America, Europe, Africa; or can choose one of the listed countries. The results can then be filtered by specific categories.
The Ranking Web of Repositories has 6 filters: world rank, country, size, visibility, files rich and scholar. The “Size” category reflects the number of web pages extracted from Google; “Visibility” shows the total number of external links received (backlinks) by the number of regerring domains for such links obtained from MajesticSEO and ahrefs databases; “Rich Files” refers to files in formats like Adobe Acrobat (.pdf), MS Word (doc, docx), MS Powerpoint (ppt, pptx) and PostScript (.ps & .eps) extracted from Google; lastly, “Scholar” is the normalised number of papers between 2007 and 2011 in Google Scholar. This way users can easily search a repository according to specific criteria and check the repository’s place in the ranking.
The Ranking is an initiative of the Cybermetrics Lab, a research group which is part of the Consejo Superior de Investigaciones Científicas (CSIC) – the largest public research body in Spain; as we can read on the website:
“The organization collaborates with other institutions of the Spanish R&D system (universities, autonomous governs, other public and private research organisms) and with social, economic, national or foreign agents to which contributes with its research capacity and human and material resources in the development of research projects or under the form of consultancy and scientific and technical support.”
These kind of initiatives can be very useful for researchers, scholars and students, who looking for repositories containing scientific materials. The ranking will help to search for repositories in an organized and categorized way. I think that this website is well worth checking.
