The California Digital Library (CDL) Digital Special Collections program directly supports University of California's (UC) mission of teaching, research, learning, and public service. It serves UC libraries, archives, and museums and non-UC institutions. It supports their mission of providing public access to unique cultural heritage materials.
As a resource aggregator, the Digital Special Collections program is committed to supporting its contributors' local collection policies. It must also maintain its own collection policy to maintain the following objectives:
This policy serves as a framework for developing collections managed by the Digital Special Collections program, for display in the Calisphere and Online Archive of California (OAC) websites. Calisphere and the OAC feature publicly-accessible, unique or rare, cultural heritage materials that serve as the basis for historical studies, analysis, and interpretation in accordance with identified and anticipated curriculum and research interests of its primary audiences, including faculty, students (university and K-12), teachers, and California citizens.
The websites seek to address the following types of primary audience activities, in particular:
We reserve the right to work with institutions to identify the most appropriate website (i.e., Calisphere or the OAC) for displaying that institution's content.
The policy additionally does not cover collections hosted by the following CDL programs:
Institutions interested in submitting content solely to these repositories should consult these programs' websites.
The following terminology is used throughout this document:

Benefits
Obligations
EAD collection descriptions and MARC records for collections and items (harvested from Melvyl® by CDL on a periodic basis) are supported from all UC and non-UC California institutions. METS digital object collections are also supported, but will be assessed for hosting on a case-by-case basis, based on compliance with this policy and CDL resources and capacity. Please contact us for more information.
We are not accepting submissions from non-California institutions at this time. We will investigate ways to integrate collection descriptions and digital objects from regional, national, and international repositories, as appropriate.
Calisphere and the OAC feature collection and item descriptions, and born-digital or digital surrogates, for primary source collections and museum artifacts which are held, curated, or maintained by UC and non-UC cultural heritage institutions in California.
This policy does not restrict collections based on thematic or subject areas at this time. This policy may be modified in the future to emphasize particular thematic or subject collecting areas, in order to meet the needs of the primary audiences of our services.
Significant forms/genres of materials represented include: graphic materials such as photographs, artwork, maps, and architectural and engineering records; print and manuscript textual documents, such as letters, diaries, oral histories, legal and financial records, and scientific logbooks; electronic records; sound records; artifacts; and ephemera.
Collections that wholly or significantly constitute the following forms/genres of primary, secondary, or derivative resources are out of scope. These items may be submitted if they are components within the context of a larger primary source collection (e.g., scattered pre-publication materials included within a larger archival collection, constituting the personal papers of an author):
* Some of these forms/genres of materials may be eligible for hosting by the CDL's eScholarship Publishing Program. We recommend that you contact the eScholarship Publishing Group for additional information.
The following digital content formats are supported at this time:
The CDL is committed to supporting newer file formats over time, in accordance with identified and anticipated needs of Calisphere and OAC primary audiences.
All EAD collection descriptions must conform to the OAC Best Practice Guidelines for Encoded Archival Description, Version 2.0 (OAC BPG EAD).
MARC collection and item descriptions are harvested from Melvyl® based on a set of documented specifications.
All METS digital objects must conform to the "Enhanced Service Level" specifications described in the CDL Guidelines for Digital Objects, Version 2.0 (CDL GDO).
A CDL Digital Special Collections staff member can consult with you on implementing strategies and open-source based tools to meet CDL specifications. Even if your institution currently does not utilize EAD or METS, we can help you identify effective options for generating content based on these standards. The CDL also maintains a number of online resources to assist contributing members.
We prefer, but do not require, that all digital objects submitted to Calisphere and the OAC are part of a larger primary source collection and that each digital object contain a reference to that collection. The reference may take the form of a unique identifier (such as a URL to an EAD collection description, web site, MARC record, etc.) or may constitute the formal title for the collection. For more information about encoding collection-related information in digital objects, see the CDL GDO, Section 3.2.1 (see also Appendix C for instructions on linking digital objects to collection descriptions).
Your institution must have rights to submit collections to Calisphere and OAC for online display. These rights should belong to one of the following four categories:
We strongly encourage institutions to provide available information about copyright owners and other restrictions in the metadata associated with digital objects, as specified in the CDL GDO. (For our general Calisphere and OAC copyright statement and conditions of use policies, see the Calisphere and OAC websites).
All EAD collection descriptions and METS digital objects featured in Calisphere and the OAC are made publicly accessible by the CDL.
The CDL does not impose exclusive publication rights to collections that it hosts in Calisphere and the OAC. Institutions may submit collections to other service providers.
There is currently no cost for CDL hosting of collections in Calisphere and the OAC. The CDL is investigating cost-recovery models for hosting of METS digital objects from non-UC institutions, however, and fees may apply in the future for hosting of new collections.
The CDL is committed to providing long-term public access to the collections that it hosts in Calisphere and the OAC, and utilizes the Archival Resource Key (ARK) specification to support the persistent identification of individual EAD collection descriptions and METS digital objects. We will work with institutions to remove public access to materials on a case-by-case basis for the following reasons:
