As previously mentioned, the OSCDL hosts data sets which can be represented in the form of an interactive map.
Maps available through the OSCDL that show the historic boundaries of urbanization of Portland were digitized, overlaid, and then exhibited at a regional planning event designed to help Portland citizens understand the physical shape of the region's growth, as well as frame a discussion about how to manage future growth.
Ninety-five percent of monographs, reports, correspondence and other planning documents selected for inclusion in the OSCDL are scanned and digitized by an outside vendor.
Metadata used to describe these documents includes geographic coordinates to support the interactive mapping feature of the OSCDL. The records are batch loaded into the catalog and linked hierarchically using Innovative Interfaces Inc.'s (III) Electronic Resource Management (ERM) product.
In addition to the PSU Library catalog access point, researchers can view material in the digital collection via the OSCDL website.
An approval queue has been implemented to hold these new documents until an OSCDL administrator can review them, at which point the files will be added to the collection.
With respect to the preservation of the digital files within the OSCDL, it should be noted that the project works upon the LOCKSS model: Lots of Copies Keep Stuff Safe.
Ideally, the OSCDL will become a key player in the community by supporting thoughtful city planning and civic engagement.
Currently, tools within the OSCDL are still in the developmental stage; however, the resource is available for public use.
