The Not Forgotten library depository

The International Time Capsule Society is  dedicated to tracking the world's time capsule to ensure that those that are created are not lost. Paul Hudson founder of ITCS and alumni of Oglethorpe University estimates that more than 80 percent of all time capsules are lost and will not be opened on their intended date.

The International Time Capsule Society collects and oversees time capsule registrations from all over the world, of all types of time capsule,  and has received many thousands of registrations for over 30 years. On receipt of a new registration the ITCS catalogs each time in the Not Forgotten Library Depository and provides public access to the Time Capsule records. 

In 2020 through formal deaccession, the physical and digital records of time capsules that Oglethorpe University holds in its possession were permanently transferred to the Not Forgotten Library Depository thereby consolidating the registry of time capsule held in the Not Forgotten Library Depository together with those held by Oglethorpe University on behalf of the International Time Capsule Society.​

All registrations received on hardcopy between 1990-2020 by the Society are currently  being mapped and digitized on behalf of ITCS by Not Forgotten by volunteer transcribers, and added to WorldCat

New registrations and volunteers can be submitted through the ITCS website. 

This is a free service funded by volunteers and resource donation.

The international time capsule registry holdings

Archives are public institutions and must be publicly accessible and available for use. The purpose of libraries are to make the world's knowledge more accessible. The Depository is designated both as a special library and an archive with OCLC (library symbol IEFDP), sharing its "library of human experience" and holdings information with the public and employing a library management system that facilitates global sharing.

Time capsules registered on the International Time Capsule Register have public library records of their capsule which are made accessible through the public OCLC library catalog.

Archival records are defined as a cultural monument in US legislation. Care and protection of archival records is defined in the declaration of archives and in the code of archival ethics.

As an archive Not Forgotten adheres to preservation policy standards set forth by the U.S. Library of Congress, the U.S. National Archives and Records Administration, and WITNESS. As an institutional member of Association of Moving Image Archivists Not Forgotten follows the recommended guidelines of the (United States) National Digital Stewardship Alliance Levels of Digital Preservation and the “Guidelines for the preservation of digital heritage” from UNESCO. The Not Forgotten preservation system aligns with the goals outlined within the Open Archival Information Systems (OAIS) Reference Model (ISO 14721:2003). Video records are maintained in a ISO-27001 certified data repository system

In accordance to these librarian and archival procedures Not Forgotten describes its holdings including information on the owners and creators of the Time Capsules. The information which is captured inside of and in association with the archive and library records will by definition be public and not private. "Advance directives” are used to enable privacy for a period, but to make the Time Capsules and Time Capsule Register all ultimately public. The records by necessity have the characteristics of the individual archiver. After the Public Availability Date the public may also obtain copies of the record in question through the library.
