History of the GSA Data Repository
The GSA Data Repository was established in 1974 as an open archive in which authors of articles in GSA journals and books could place information that supplemented and/or expanded on their article. A unique number was included in a footnote with the printed article (ex: 2007001 is entry 1 for 2007). Hard copies were mailed on request until the Repository went online. In the early 2000s, the remaining hard copies were scanned and posted online as well. In 2020, GSA moved the Repository to Figshare.
