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
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,...

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...

Web archive data from a crawl of open access PDF URLs provided by Unpaywall.
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 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.
Test runs of large-scale matching algorithms (sha1 to DOI). Will likely be obsolete soon, and not useful for others.
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.

Crawl of "upstream" URLs from CORE (core.ac.uk) metadata dump. Only a partial seedlist of files crawled.
See also the crawl logs item for this crawl.
Crawl reports and logs for CORE-UPSTREAM-CRAWL-2018-11 crawl. See also 'CORE-UPSTREAM-CRAWL-2018-11-full_crawl_logs' item.
"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.
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 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.
This item contains bulk metadata exported from https://fatcat.wiki. With the exception of the 'abstracts' file (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.

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 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.

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)...
