    Abstract
    This paper reports the results of a study that examined Arabic-speaking children's interaction with the International Children's Digital Library (ICDL). Assessment of the ICDL to Arabic-speaking children as a culturally diverse group was grounded in "representations" and "meaning" rather than in internationalization and localization. The utility of the ICDL navigation controls was judged based on the extent it supported children's navigation. Most of the ICDL representations and their meanings were found to be highly appropriate for older children but inappropriate for younger ones. The design of the ICDL navigation controls was supportive of children's navigation. Recommendations for assessing the cross-cultural usability of the ICDL are made and suggestions for system design improvements are provided.

    Abstract
    This paper reports the results of a study that investigated Arabic-speaking children's interaction with the International Children's Digital Library (ICDL) to find Arabic books on four tasks. Children's information seeking activities was captured by using HyperCam software. Children's success was assessed based on a measure the researchers developed. Children's perceptions of and affective experience in using the ICDL was gathered through group interviews. Findings revealed that children's information seeking behavior was characterized by browsing using a single function; that is, looking under "Arabic" from the Simple interface pull-down menu. Children were more successful on the fully self-generated, open-ended task than on the assigned and semi-assigned tasks. Children made suggestions for improving the Arabic collection and the design of the ICDL. The findings have implications for practitioners, researchers, and system designers.

    Abstract
    Bilal, in this third part of her Yahooligans! study looks at children's performance with self-generated search tasks, as compared to previously assigned search tasks looking for differences in success, cognitive behavior, physical behavior, and task preference. Lotus ScreenCam was used to record interactions and post search interviews to record impressions. The subjects, the same 22 seventh grade children in the previous studies, generated topics of interest that were mediated with the researcher into more specific topics where necessary. Fifteen usable sessions form the basis of the study. Eleven children were successful in finding information, a rate of 73% compared to 69% in assigned research questions, and 50% in assigned fact-finding questions. Eighty-seven percent began using one or two keyword searches. Spelling was a problem. Successful children made fewer keyword searches and the number of search moves averaged 5.5 as compared to 2.4 on the research oriented task and 3.49 on the factual. Backtracking and looping were common. The self-generated task was preferred by 47% of the subjects.

    Abstract
    This study compared the search features and retrieval performance of Yahooligans!, Ask Jeeves for Kids, and Super Snooper on identical searches. This extended the earlier research conducted by Bilal (1999), which examined the cognitive, affective, and physical behaviors of twenty-two 7th grade science students' use of Yahooligans! search engine. The three types of searches the students formulated in Yahooligans! on an imposed fact-driven query were here conducted in Ask Jeeves for Kids and Super Snooper. The retrieval performance criteria of the three engines included: (1) retrieval output, (2) relevance, (3) overlap in results, and (4) redundancy. A matrix of features (e.g., database coverage, search interface, search capabilities, retrieval interface, filtering, feedback, online help, FAQs, and advertisements) was developed to compare the engines. The performance of the natural language capability embedded in Ask Jeeves for Kids was evaluated by comparing the results retrieved directly from Yahooligans! to those Ask Jeeves for Kids returned from Yahooligans! on identical searches.The. results shed light on the strengths and weaknesses of each engine and appropriateness to specific types of queries. Yahooligans! was the most effective on keyword searching. Super Snooper returned the highest number of hits but with zero relevance on all types of searches. Ask Jeeves for Kids was successful only on one keyword search and failed both the natural language phrase and multiple keyword. Implications are made for improving the engines' design, retrieval performance, and search features, as well as for user instruction
