This item contains some bulk research affiliation datasets from Internet Archive cataloging efforts. These are mostly strings included in research papers that indicate the institutional affiliations of specific authors (eg, with a home department, university, or company) at the time of publication. These might be useful datasets for efforts to build complete indices of research organizations, or to test normalization code that maps raw strings to organization identifiers.

This item contains both metadata and fulltext PDF content (from the public web) related to research on COVID-19 and past influenza pandemics. This content backs the https://covid19.fatcat.wiki search interface. Rough numbers: - over 51,000 metadata records from 2020-04-10 release of CORD19 corpus - over 79,000 metadata records total (union of the above plus fatcat.wiki keyword matches) - over 45,000 fulltext PDF files and derived PNG thumbnails and pdftotext text files The upstream...
Topic: COVID-19, Coronavirus, SARS-CoV-2
This item contains SPARQL query exports of journal metadata from wikidata; in particular ISSN/QID mappings. The SPARQL query run is included as wikidata.sparql

This item contains a copy of log files found on the Internet Archive (Web Group) machine `wbgrp-svc263.us.archive.org` on 2018-05-29, under the `/3` directory. These are logs of file transfer status between various crawler machines; they are not known to contain any sensitive metadata (eg, personal information, IPs, or other security-sensitive information), but are being keep `access-restricted` anyways. This data is almost certainly unimportant and could be deleted; it is being preserved out...

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
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.
URL lists to PDFs on the web (and preserved in the wayback machine) which are likely to contain research materials.
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 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.
Test runs of large-scale matching algorithms (sha1 to DOI). Will likely be obsolete soon, and not useful for others.
This item contains output files related to the DOI-LANDING-CRAWL-2018-06 crawl of Crossref DOI redirect landing pages: - list of Crossref DOI numbers attempted - an index of DOI, URL, and final HTTP status codes
"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.

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!
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.
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 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 item contains a complete PostgreSQL SQL database snapshot from https://fatcat.wiki, in binary 'pg_dump tar mode' format. With the exception of the 'abstracts' table (for which no aggregate license or copyright claims can be made; downstream users are responsible for their use), all metadata here is licensed CC-0 (public domain release) and may be used for any purpose. Downstream users are strongly encouraged to provide attribution and link here to the snapshot, as well as give credit to...
