Museums hold various collections consisting of several hundreds or thousands of artifacts. A viewing system for exhibiting images from a collection simultaneously as well as efforts to find an objective material for historical research have been discussed. A new means of display can be realized through the application of a super high-definition free viewing system to arrange the graphical data containing individual artifact images. A user can search an objective image by zooming in; continuously displaying the whole collection of images while comparing its surroundings on the display and can observe its detail directly.To apply the viewing system to an exhibition with images arranged freely and enable display of the retrieval image, a method of reading out hierarchical imaged data of individual artifacts upon specific request or as a result of retrieval has been introduced. This method is applicable for image retrieval when the number of overall hits is below 200 or so. However, for exhibitions with greater numbers of artifacts, rearranged image data generation for layers with small magnification ratios is applicable.An analysis of log data has revealed that general user views involved arrayed images over a relatively wide range of magnification ratios and users who searched for objective material often viewed arrayed images with 50 to 200 images displayed simultaneously. It becomes clear that the simultaneous display of over a thousand images and free display at a size appropriate for users is effective in terms of displaying and searching images within a collection.
