    Abstract
    Examines the RANK command on DIALOG using a statistical analysis of articles in DATABASE as an example. The RANK command was used to find authors, company names, and length of articles. Use of the command revealed a number of complexities and revealed some problematic indexing on the part of the database producers. The LEXIS-NEXIS RANK command was also used, but this fulfils a different function to the command of the same name in DIALOG

    Abstract
    Describes the RANK command which enables searchers of DIALOG databases do statistical analysis online. Describes the basic features of the ranking command. The fields to which this command can be applied run into the thousands. Shows how RANK can be used for content analysis. Details the limitations of the command and compares it with the SORT command. Offers advice on ranking results without using this command
