California Digital Preservation Service

The California Preservation Program (CPP) offers California libraries, archives, and museums a comprehensive array of digital preservation services. The DPS works with partners to identify, preserve, and provide online access to moving image and sound recordings, photographs, books, documents, manuscripts, and ephemera that bring California history to life. The resulting California Light and Sound Collection currently includes more than 8,000 digital objects from over 140 partner organizations, with nearly two million views to date.

The DPS implements grant-funded projects, including the California Audiovisual Preservation Project and the California Revealed project. Additionally, if your institution is digitizing materials in-house, the DPS team of librarians and digital archivists is available for technical advice and guidance at no cost to you. If your content is related to California history, the DPS can serve and preserve your digital objects as part of the California Light and Sound Collection, again at no cost to you. These free services are underwritten by the California State Library. For more information, please contact dps@calpreservation.org.

DPS services include:
● Assisting partner institutions to identify historically important records in their collections.
● Managing the complete digitization workflow including communicating with vendors, shipping archival materials, and tracking physical and digital objects.
● Maintaining and updating digitization procedures in accordance with FADGI guidelines and best practices for digital capture.
● Packaging digital objects for ingest in the digital repository.
● Maintaining a digital repository to serve and preserve partner digital assets.
● Aggregating, standardizing, and mapping metadata for ingest to the digital repository.
● Assisting with minimum cataloging for unprocessed collections with an eye towards improving discoverability.
● Providing expert quality control of content to ensure that digital files meet playback standards and file specifications. Because of the intensive nature of QC, we are often able to correct or enhance cataloging information during the course of this review for better discoverability and user engagement.
● Ensuring offline preservation storage on redundant, geographically dispersed Linear Tape-Open (LTO) data tape.
● Performing regularly scheduled file integrity checks on preservation storage files.
● Providing free public online access via the Internet Archive at californialightandsound.org.
