OverviewWhat is an Digital Library?Overview of Ongoing Research on Information Access in Digital Libraries
Digital Libraries Are Like Traditional Libraries...Involve large repositories of information (storage, preservation, and access) Provide information organization and retrieval facilities (categorization, indexing) Provide access for communities of users (communities may be as large as the general public or small as the employees of a particular organization)
Traditional Library System
But Digital Libraries Are Different From Libraries...Not a physical location with local copies; objects held closer to originators Decoupling of storage, organization, access Enhanced Authoring (origination, annotation, support for work groups) Subscription, pay-per-view supported in addition to free browsing. Integration into user tasks.
A Digital Library Infrastructure Model
UC Berkeley Digital Library ProjectFocus: Work-centered digital information servicesTestbed: Digital Library for the California EnvironmentResearch: Technical agenda supporting user-oriented access to large distributed collections of diverse data types.Part of the NSF/NASA/DARPA Digital Library Initiative (Phases 1 and 2)

Testbed: An EnvironmentalCollection: Diverse material relevant to Californias key habitats.Users: A consortium of state agencies, development corporations, private corporations, regional government alliances, educational institutions, and libraries.Potential: Impact on state-wide environmental system (CERES )

The Environmental Library - ContentsEnvironmental technical reports, bulletins, etc.County general plansAerial and ground photographyUSGS topographic mapsLand use and other special purpose mapsSensor dataDerived informationCollection data bases for the classification and distribution of the California biota (e.g., SMASCH)Supporting 3-D, economic, traffic, etc. modelsVideos collected by the California Resources Agency
The Environmental Library - ContentsAs of late 2000, the collection represents about one terabyte of data, including over 165,000 digital images, about 300,000 pages of environmental documents, and nearly 2 million records in geographical and botanical databases.
The CalFlora Database contains taxonomical and distribution information for more than 8000 native California plants. The Occurrence Database includes over 600,000 records of California plant sightings from many federal, state, and private sources. The botanical databases are linked to our CalPhotos collection of Calfornia plants, and are also linked to external collections of data, maps, and photos.
Much of the geographical data in our collection is being used to develop our web-based GIS Viewer. The Street Finder uses 500,000 Tiger records of S.F. Bay Area streets along with the 70,000-records from the USGS GNIS database. California Dams is a database of information about the 1395 dams under state jurisdiction. An additional 11 GB of geographical data represents maps and imagery that have been processed for inclusion as layers in our GIS Viewer. This includes Digital Ortho Quads and DRG maps for the S.F. Bay Area.
Most of the 300,000 pages of digital documents are environmental reports and plans that were provided by California state agencies. This collection includes documents, maps, articles, and reports on the California environment including Environmental Impact Reports (EIRs), educational pamphlets, water usage bulletins, and county plans. Documents in this collection come from the California Department of Water Resources (DWR), California Department of Fish and Game (DFG), San Diego Association of Governments (SANDAG), and many other agencies. Among the most frequently accessed documents are County General Plans for every California county and a survey of 125 Sacramento Delta fish species.
Documents - cont.
The collection also includes about 20Mb of full-text (HTML) documents from the World Conservation Digital Library. In addition to providing online access to important environmental documents, the document collection is the testbed for our Multivalent Document research.

Spectrum of Digital Document Representations
Adapted from Fox, E.A., et al. Users, User Interfaces and Objects: Evision, an Electronic Library, JASIS 44(8), 1993
Document Representation: Multivalent DocumentsPrimary user interface/document model for UCB Digital Library (Wilensky & Phelps)Goal: An approach to new document representations and their authoring. Supports active, distributed, composable transformations of multimedia documents. Enables sophisticated annotations, intelligent result handling, user-modifiable interface, composite documents.
