This item contains three .zip archives, each containing a sample corpus of about 10,000 (or more) HTML documents from the IA web archive. For each, there is some form of metadata (CDX or JSON) with information about the original URL and timestamp for each document, and then directories containing HTML, extracted TEI-XML, and extracted TXT for each document. There are some fraction of documents which failed to download or failed to extract, so there are fewer .html (and derivative) files than...

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!
"Full" crawl logs (for every hit) from CORE-UPSTREAM-CRAWL-2018-11 crawl. See also 'CORE-UPSTREAM-CRAWL-2018-11-CRL' item for reports etc.

About 1 million unique PDFs from Global Wayback before year 2000.
This dump includes all tables (including oauth authentication tables which could be a privacy, but not security, concern). At this time only IA staff have accounts, so the snapshot, which is intended mostly for disaster recovery, is still public.
This is a derivative of https://archive.org/download/ia_papers_manifest_2018-01-25, which contains JSON objects that can be inserted into a fatcat catalog.

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)...
URL lists to PDFs on the web (and preserved in the wayback machine) which are likely to contain research materials.
Test runs of large-scale matching algorithms (sha1 to DOI). Will likely be obsolete soon, and not useful for others.
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 hash lists of PDF files crawled from the public web specifically to preserve the scholarly record. It does not contain hashes of *all* PDFs the archive has ever seen, only a subset. Not all of these hashes are necessarily journal articles or other research outputs, but we have reason to believe the large majority are.
Data-munged title-level metadata combined from: DOAJ, ROAD, Norwegian Register, and Internet Archive crawled metadata. See SOURCES.md for URLs of upstream metadata, and ISSN_matching.html for Jupyter notebook used to derive this dataset.

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,...

A series of open web crawls targeting journal articles, technical memos, essays, datasets, and other research publications. This collection contains WARC and CDX files that end up in Wayback ( https://web.archive.org ). See also bibliographic metadata corpuses at https://archive.org/details/ia_biblio_metadata

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 is a mapping between: - DOIs (Crossref) - PubMed PMID and PMCID (NIH) - CORE record identifier (core.ac.uk) - Wikidata QIDs See README and scripts for details.
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.
