    Abstract
    To determine influences on the production of a scientific article, the content of the article must be studied. We examined articles in biogeography and found that most of the influence is not cited, specific types of articles that are influential are cited while other types of that also are influential are not cited, and work that is uncited and seldom cited is used extensively. As a result, evaluative citation analysis should take uncited work into account.

    Abstract
    For several decades we, among others, have criticized the use of citations for evaluative purposes. Although these criticisms have been noted, they have been largely brushed aside or ignored, not addressed head on. This may be for a number of reasons, but we believe the main one is that these criticisms undermine the desire to have an easy "scientific"-that is, quantitative-method of evaluation. Consequently, we continue and update our criticism of the use of citations for evaluation.
