Preservation Technologies (PTLP) is a company dedicated to helping universities, academic institutions, cultural entities and private companies preserve and maintain access to their collections. PTLP was founded on the guiding principle of bringing engineering and innovation to the field of cultural preservation.

Preservation Technologies was officially established in 1992 after successfully developing the patented Bookkeeper® process, which extends the life of books and manuscripts by neutralizing the harmful acids found in paper. 14 years later, Preservation Technologies then expanded its services to help clients preserve other audio, video, and film collections and introduced The MediaPreserve.

As we celebrate this milestone anniversary, Preservation Technologies would like to acknowledge those that made the past 25 years possible. Thank you to our clients for your trust and loyalty through the years.
