- Abstract
- Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

- Abstract
- Wie wird aus einem Garagen-Start-up ein weltbekanntes Imperium? Das Geheimnis um Google, eine der wertvollsten Marken der Welt,ist gelüftet. Von niemand Geringerem als Google-CEO Eric Schmidt, Gründer Larry Page und Senior Vice President Jonathan Rosenberg. Und so wie Google längst mehr als eine Suchmaschine ist, ist »Wie Google tickt« weit mehr als eine Unternehmensgeschichte. Es ist spannende Inspirationsquelle und kluger Wegweiser. Wie baut man eine fruchtbare Unternehmenskultur auf? Wie entwickelt man wegweisende Strategien? Wie entsteht Innovation? Die drei Google-Insider sind angetreten, ihr Wissen in die Welt zu bringen. Eric Schmidt ist Informatiker und war langjähriger CEO von Google. Seit April ist er Executive Chairman von Google. Schmidt lehrt an der Stanford University und gehört seit 2009 zum Beraterteam von Barack Obama. Jonathan Rosenberg, Senior Vice President von Google, war vor allem für die innovative Produktentwicklung verantwortlich. Zusammen sind sie echte Google-Insider.
