There are some fraction of documents which failed to download or failed to extract, so there are fewer .html (and derivative) files than...

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.

This crawl started in April 2019, as an informal collaboration with Crossref. Crawling a smallish number (100k) DOI redirects and landing pages (plus PDF outlinks, and maybe a couple other hops) for a single large publisher (OMICS, which has multiple subsidiaries). Intent is to get reasonably good capture that can be used as canonical preservation copies of the landing pages. Secondary goal is to get decent fulltext capture coverage.

This collection contains web crawl data for a random selection of 500k (0.5 million) Crossref DOI redirects, including the doi.org redirect requests. The intent of this crawl is to gather loose statistics on the number of failing redirects, number of host websites that block automated crawling, and a corpus of HTML landing pages for metadata extraction (eg, "signposting" HTTP headers, linked data HTML metadata, semantic markup). Total size of (uncompressed) WARC data is 50 GB,...

Snapshot of Internet Archive (petabox) file-level metadata (eg, PDF hashes) for files under the 'journals' collection as of December 2018. Note: includes a small number of items not actually under the 'journals' collection hierarchy due to how the input item list was generated, and a small fraction (estimate 500?) of items didn't dump successfully. A bit sloppy!
