MARC (Mailing list ARChive) is a computer-related mailing list archive. It archives over 31 million e-mails from over 2400 mailing lists, with approximately 320,000 new mails added per month. The archive is hosted by the companies 10East (formerly called the AIMS Group) and KoreLogic, and is maintained by a group of volunteers led by Hank Leininger.
MARC was founded in 1996 to serve as a unified archive of electronic mailing lists, similar to what DejaNews (now Google Groups) did for Usenet.
MARC uses a MySQL relational database to store its messages and Perl to access the data. The archive can be searched for mailing list names, authors, subject lines and full-text of the e-mail messages.
