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.

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.
About 1 million unique PDFs from Global Wayback before year 2000.

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...

Crawl of "upstream" URLs from CORE (core.ac.uk) metadata dump. Only a partial seedlist of files crawled.
This item contains sqlite3 database snapshots, URL crawl status, and other metadata useful for doing analytics on journal OA coverage, homepage status, etc. Particularly in the context of https://fatcat.wiki. Source code: https://github.com/bnewbold/chocula
Contains a TSV file with SHA1, file size, wayback URLs, and metadata extracted from PDF by GROBID. Not intended for external use, but might be interested. DOES NOT CONTAIN FULLTEXT CONTENT.

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 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. Attribution and links...

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,...

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.
