    Abstract
    Outlines the results of a pilot study designed to consider what constitutes a landmark in hypertext. Tests users' memories for locations visited on the WWW. Reports the results, and outlines a refined methodology for a new study. By understanding more about users' navigation through hypertext information space, the issue of recognition of informative materials on the WWW may be addressed

    Abstract
    For effective access to images, the design of the database interface must be based on principles that match the actual querying needs of users. Analysis of this design problem reveals that the query language must support utilization of both visual and verbal clues. The ViewFinder interface, designed as a client to a database server, supports querying based on both types of clues. Presents details of ViewFinder design. Describes results of usability analysis performed on ViweFinder with a group of 18 users. High search success rates were achieved (greater than 80%) through both types of querying means (visual and verbal). Users generally used more verbal clues than visual clues in searches
