- Enhanced Library Collection Access through GIS: Historic Colorado Aerial Photographs
- This case study presents the use of GIS in a map library to create an enhanced index for a collection of historical aerial photographs of Colorado. The University of Colorado at Boulder’s Jerry Crail Johnson Earth Sciences and Map Library scanned and indexed 1700 aerial photographs taken from 1938- 1947. Library staff used ArcView 3.2 and ArcGIS 8.1 to plot the center points of each photograph and enhanced the georeferencing with a detailed attribute table. The project Web site provides access to the photographs and the spatial data captured in the attribute table through a map search and a keyword search.

- The flight plan of a digital initiatives project, part 2: Usability testing in the context of user-centered design
- Purpose – To provide the results of research to evaluate the usability of a University of Colorado at Boulder Libraries digital initiatives project that provides online access to historical Aerial Photographs of Colorado. Design/methodology/approach – This paper describes usability testing conducted as a part of a user‐centered redesign. The three stages of the evaluation – a requirements analysis, a heuristic evaluation, and user testing – are explained and the findings are discussed. Findings – The usability testing revealed the needs of the project's target user group and identified issues with the interface that will be addressed in its redesign. It has also contributed to the larger understanding of how researchers use digital Aerial Photographs and their preferred methods of access and desired functionalities. Practical implications – Results from the study will be used to guide the redesign of the Aerial Photographs of Colorado digital library and can be generalized to add to a broader understanding of the usability requirements for a digital library of geospatial materials. Libraries providing a digital collection of geospatial materials may use these findings to inform design decisions. Originality/value – Much research has been done on the use and evaluation of digital libraries, but few articles have reported on usability studies of online collections of cartographic materials similar in structure to Aerial Photographs of Colorado. It is hoped that these findings will be instructive to librarians designing and evaluating similar digital libraries.

- The flight plan of a digital initiatives project: Providing remote access to aerial photographs of Colorado
- Purpose – To present a case study of a digital initiative for cartographic materials in order to provide a reference for other institutions embarking on similar projects. Design/methodology/approach – Describes the technical and practical details of the processes involved in georeferencing and providing online access to scanned aerial photographs. Findings – In the short time that the site has been live, the Map Library has already seen a marked increase in reference queries from both local and national users. Practical implications – From a practical standpoint, the project would not have been a success without collaboration between map, metadata, and systems librarians. Originality/value – To date, little has been published about digital initiatives projects providing online access to historical aerial photographs, a distinct and complex subset of cartographic materials. It is hoped that this case study will allow other institutions to learn from the approach and experience of the University of Colorado at Boulder Libraries.
