Launched by the Lund University Libraries and sponsored by the Open Society Institute and The Royal Library of Sweden, the Directory of Open Access Journals (DOAJ) is a service gathering and linking free, full-text, peer-reviewed scientific and scholarly journals available online. More than 7,200 journals are included in the directory with direct link to their website and free contents. Each journal must guarantee a peer-review precedure or an editorial quality control to be part of the DOAJ directory. Currently 3,000 of these journals are also directly searchable by article in the DOAJ pages without being redirected to the journal websites, for a total number of over 700,000 articles. All scientific and scholarly subjects are covered and all contents are freely available in full-text, usually in pdf format. Resources are catalogued by journal title and can be browsed by an expandible subject index, while for those journals providing to DOAJ the requested metadata to be searchable by article, also a simple multiple search feature is available. Any journal issue is provided with basic metadata such as publisher, year of publication, keywords, and with direct link to the journal website while for those records labeled as “DOAJ Content”, abstract and full text are directly available from the DOAJ webpages . Navigation in this website is extremely simple even for non-experts.
