A major figure to emerge in the history of American photography is Carlotta Corpron (1901-1987), who taught art at Texas Woman's University in Denton, Texas from 1935-1968. The rediscovery of her abstract images created during the 1940s reflects the growing recognition of the experimental photography at the New Bauhaus in Chicago from 1937-1946. Corpron's abstract photographs were stimulated by her interaction with Lazlo Moholy-Nagy and Gyorgy Kepes. Corpron was an innovator in the development of abstract photography in the United States. This thesis connects her work to that of Moholy-Nagy and Gyorgy Kepes as well as other major figures in American photography of the twentieth century.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems. Empirical data has been collected by observations made in the two systems as they are made available by Mölndals museum (Sofie) and Göteborgs Stadsmuseum (Carlotta). The results of this study show that the systems need to meet the requirements of the public, the end-users, to a larger extent. Sofie is easy to learn and to use, but over-simplifying the system negatively affects the possibility to effectively access data. Carlotta is a complex system that holds many possibilities to access semantically related data easily. The complexity of the system requires more information about the structure of the system and the different functions available for the user. The representations of objects need to be more consistent in order for the end-users to retrieve them by searching. Additional access points made possible by the implementation of a directory sorted by subject would be beneficial. / Uppsatsnivå: D
