    Abstract
    Aggregated journal-journal citations can be used for mapping the intellectual organization of the sciences in terms of specialties because the latter can be considered as interreading communities. Can the journal-journal citations also be used as early indicators of change by comparing the files for two subsequent years? Probabilistic entropy measures enable us to analyze changes in large datasets at different levels of aggregation and in considerable detail. Compares Journal Citation Reports of the Social Science Citation Index for 1999 with similar data for 1998 and analyzes the differences using these measures. Compares the various indicators with similar developments in the Science Citation Index. Specialty formation seems a more important mechanism in the development of the social sciences than in the natural and life sciences, but the developments in the social sciences are volatile. The use of aggregate statistics based on the Science Citation Index is ill-advised in the case of the social sciences because of structural differences in the underlying dynamics.

    Abstract
    Data were gathered on acknowledgements in five leading information science journals for the years 1991-1999. The results were compared with data from two earlier studies of the same journals. Analysis of the aggregate data (1971-1999) confirms the general impression that acknowledgement has become an institutionalised element of the scholarly communication process, reflecting the growing cognitive and structural complexity of contemporary research.

    Abstract
    A citation analysis of undergraduate term papers in microeconomics revealed a significant decrease in the frequency of scholarly resources cited between 1996 and 1999. Book citations decreased from 30% to 19%, newspaper citations increased from 7% to 19%, and Web citations increased from 9% to 21%. Web citations checked in 2000 revealed that only 18% of URLs cited in 1996 led to the correct Internet document. For 1999 bibliographies, only 55% of URLs led to the correct document. The authors recommend (1) setting stricter guidelines for acceptable citations in course assignments; (2) creating and maintaining scholarly portals for authoritative Web sites with a commitment to long-term access; and (3) continuing to instruct students how to critically evaluate resources

    Abstract
    He and Spink count the first authors in JASIST and JDoc from 1950 to 1999 whose affiliation is outside the country of origin of each publication and record the time period and the author's geographic location. Foreign authorship in JASIST increased nearly four fold from 1995 to 1999 and the number of represented locations 3.6 times while in the same time period JDoc's foreign authorship doubled and foreign locations increased four fold. The largest foreign location for JDoc is the USA and the largest foreign location for JASIST is the UK. Canada is second on both lists.
