A mirror of the Unpaywall (aka oaDOI.org) metadata corpus, primarily consisting of public open access flags for a large number of Crossref-registered DOIs (identifiers representing published journal articles and other works). For more information see: http://unpaywall.org/products/snapshot
This item contains datasets of homepage URLs found by hand using search engines and bibliographic metadata (eg, ISSN and journal title). The "long-tail" batch contains about 4,600 journal lookup results, with about 3,900 successful homepage URLs found. The list of journals was created in May 2020, and the lookup work completed in June 2020. IA staff member Richard Greydanus ran this batch of lookups. All of this metadata can be considered public domain, or CC-0 (Creative Commons Zero)...
This item contains an example corpus of citations between scholarly documents, as extracted from the fatcat (https://fatcat.wiki) corpus as of the 2020-08-05 bulk release export. This corpus itself was generated from a fatcat-scholar "intermediate" fulltext dump which is not public, using software in the fatcat-scholar repository in mid-September 2020. See also the README for some more notes, and the "sample" file.
