Preservation Technologies successfully developed the patented Bookkeeper® process, which extends the life of books and manuscripts by neutralizing the harmful acids found in paper. PTLP was officially established in 1992 as a limited partnership. Reflecting on successful operations for eight years, Library of Congress requested a partnership with PTLP to set up a facility specifically to treat manuscripts and records in the Madison Building.

Bookkeeper® is the only deacidification method to meet the standards of the Library of Congress as well as current and projected OSHA, FTC and EPA consumer and environmental requirements. Over 550,000 assets from library and archival collections are sent to Preservation Technologies global facilities each year to be deacidified.

Having developed a reputation as a worldwide leader in paper preservation, Preservation Technologies was in a unique position to expand its services to help clients preserve other cultural collections. Large research libraries including NYU, Library of Congress and members of the Committee for Institutional Cooperation would often comment on the need to reformat and preserve their important audio, video and film collections. The MediaPreserve was founded in 2006 as a response to this need. It offers studios designed for both the handling and transfer of delicate one-off materials and high-capacity multiple ingest of robust cassette-based formats. All ingest is fully-monitored to ensure the quality of each file produced. We have developed painstaking quality control procedures to guarantee file integrity and have successfully initiated the automation of metadata to accompany these digital files.
