    Abstract
    This article studies the probabilities of the occurence of multi-word (m-word) phrases (m=2,3,...) in relation to the probabilities of occurence of the single words. It is well known that, in the latter case, the lae of Zipf is valid (i.e., a power law). We prove that in the case of m-word phrases (m>=2), this is not the case. We present 2 independent proof of this

    Abstract
    The quality of online and CD-ROM databases is far from satisfactory. Errors are frequently found in listings from online searches. Spelling mistakes are the most common but there are also more misleading errors such as variations of an author's name or absence of homogenity in the content of certain field. Describes breifly a bibliometric study of large amounts of data downloaded from databases to investigate bibliographic errors and data heterogeneity. Recommends that database producers should consider either the implementation of a common format or the recommendations of the Société Française de Bibliométrie
