    Abstract
    Analyzes 200 papers produced by a multidisciplinary natural sciences institute in a 10 years period for the context of the citation they received during the 21 year period since their publication. They were grouped in 28 research topics from physics, chemistry, to biology, and there were some half a dozen papers per topic on the average. 11% of all the citing papers comprised the sample of the context analysis: 1 citing per each cited paper. Sets of citing papers of each research topic were taken as units in the analysis

    Abstract
    A citation analysis examined the 28 best articles published in JASIS from 1969-1996. Best articles tend to single-authored works twice as long as the avergae article published in JASIS. They are cited and self-cited much more often than the average article. The greatest source of references made to the best articles is from JASIS itself. The top 5 best papers focus largely on information retrieval and online searching
