    Abstract
    User-friendly and content-rich Web sites are indispensable for any knowledge-based organization. Web site evaluation studies point to ways to improve the efficiency and usability of Web sites. Library catalog or technical services department Web sites have proliferated in the past few years, but there is no systematic and accepted method that evaluates the performance of these Web sites. An earlier study by Mundle, Zhao, and Bangalore evaluated catalog department Web sites within the consortium of the Committee on Institutional Cooperation (CIC) libraries, proposed a model to assess these Web sites, and recommended desirable features for them. The present study was undertaken to test the model further and to assess the recommended features. The study evaluated the catalog department Web sites of Association of Research Libraries members. It validated the model proposed, and confirmed the use of the performance index (PI) as an objective measure to assess the usability or workability of a catalog department Web site. The model advocates using a PI of 1.5 as the benchmark for catalog department Web site evaluation by employing the study tool and scoring method suggested in this paper.

    Abstract
    Cologne Library School ran a project to construct a database for literature on content cataloguing and fringe disciplines. Software was the BISMAS 1.0 programme and is now the 1.5 version. The category scheme, indexes and retrieval possibilities are described. Retrieval is mainly free text, using the whole document description and all descriptive categories. BISMAS does not permit standard data file administration so a further database was provided ...

    Abstract
    The study of the web as a graph is not only fascinating in its own right, but also yields valuable insight into web algorithms for crawling, searching and community discovery, and the sociological phenomena which characterize its evolution. We report on experiments on local and global properties of the web graph using two Altavista crawls each with over 200M pages and 1.5 billion links. Our study indicates that the macroscopic structure of the web is considerably more intricate than suggested by earlier experiments on a smaller scale

    Abstract
    Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution. We find that hominin brains experienced positive rate changes at 2.1 and 1.5 million years ago, coincident with the early evolution of Homo and technological innovations evident in the archeological record. But we also find that human brain size reduction was surprisingly recent, occurring in the last 3,000 years. Our dating does not support hypotheses concerning brain size reduction as a by-product of body size reduction, a result of a shift to an agricultural diet, or a consequence of self-domestication. We suggest our analysis supports the hypothesis that the recent decrease in brain size may instead result from the externalization of knowledge and advantages of group-level decision-making due in part to the advent of social systems of distributed cognition and the storage and sharing of information. Humans live in social groups in which multiple brains contribute to the emergence of collective intelligence. Although difficult to study in the deep history of Homo, the impacts of group size, social organization, collective intelligence and other potential selective forces on brain evolution can be elucidated using ants as models. The remarkable ecological diversity of ants and their species richness encompasses forms convergent in aspects of human sociality, including large group size, agrarian life histories, division of labor, and collective cognition. Ants provide a wide range of social systems to generate and test hypotheses concerning brain size enlargement or reduction and aid in interpreting patterns of brain evolution identified in humans. Although humans and ants represent very different routes in social and cognitive evolution, the insights ants offer can broadly inform us of the selective forces that influence brain size.

    Abstract
    Search engine coverage relative to the estimated size of the publicly indexable web has decreased substantially since December 97, with no engine indexing more than about 16% of the estimated size of the publicly indexable web. (Note that many queries can be satisfied with a relatively small database). Search engines are typically more likely to index sites that have more links to them (more 'popular' sites). They are also typically more likely to index US sites than non-US sites (AltaVista is an exception), and more likely to index commercial sites than educational sites. Indexing of new or modified pages byjust one of the major search engines can take months. 83% of sites contain commercial content and 6% contain scientific or educational content. Only 1.5% of sites contain pornographic content. The publicly indexable web contains an estimated 800 million pages as of February 1999, encompassing about 15 terabytes of information or about 6 terabytes of text after removing HTML tags, comments, and extra whitespace. The simple HTML "keywords" and "description" metatags are only used on the homepages of 34% of sites. Only 0.3% of sites use the Dublin Core metadata standard.

    Abstract
    Charles Stevens, of the Salk Institute in La Jolla, California, takes a still different approach, arguing that the number of cells can tell you more than the volumes of different regions. "Our brain is no different from a mouse's," he says, "but we have a lot more of it." Stevens has counted the cells in two regions of the cortex: the lateral geniculate nucleus (LGN), one of the first destinations for nerve signals from the retina, and the primary visual cortex, the next port of call for LGN messages. He found that, in a range of primate species, the number of cells in the primary visual cortex is proportional to the number of cells in the LGN raised to the power of 1.5. So a human uses four times as many neurons to process the input from each LGN neuron as a tarsier, a small Asian primate. Stevens suggests that bigger animals with bigger eyes need proportionally more cortical cells to process the information they receive without sacrificing resolution.
