The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed by the UNT Libraries on the US Federal Executive, Legislative & Judicial branches of government in 2020-2021. The seeds for these crawls came from human-nominated URLs that can be viewed in the
Nomination Tool as well as from
lists generated by volunteers at UC San Diego and Environmental Data & Governance Initiative (EDGI).

Set of Identifications, Measurements, and Bibliography for Astronomical Data (SIMBAD)
The Set of Identifications, Measurements, and Bibliography for Astronomical Data (SIMBAD), created and maintained by the CDS, Strasbourg, brings together basic data, cross-identifications, observational measurements, and bibliography, for celestial objects outside the solar system: stars, galaxies, and nonstellar objects within our galaxy, or in external galaxies. SIMBAD contains information for about 1 million objects, for which 3.3 million identifiers, more than 1.5 million observational measurements and 1.4 million bibliographical references are available.
