Title: | Reflections on a deflection: a note on different causes of the Groos droop | Authors: | EGGHE, Leo ROUSSEAU, Ronald |
Issue Date: | 1988 | Publisher: | ELSEVIER SCIENCE BV | Source: | SCIENTOMETRICS, 14 (5-6), p. 493-511 | Abstract: | In this paper different aspects that cause the so-called Groos droop, are investigated. We start from pure Bradfordian data (i.e. without a Groos droop) and discuss what actions can cause a deflection on the Bradford-Leimkuhler curve. It is, of course, well-known, that incompleteness of the data is one aspect, but we show that taking unions of pure Bradfordian bibliographies can also yield a bibliography with a Groos droop. As such, a Groos droop can always be expected in interdisciplinary bibliographies. In this way we suggest an explanation for the experimental differences between the micro-and macro-curves obtained byBonitz andSchmidt (Scientometrics, 4 (1982) 283.). In conclusion we may say that the Groos droop can be explained through Bradford's law and hence that they do not contradict each other. | Notes: | KATHOLIEKE IND HOGESCH W VLAANDEREN,B-8400 OOSTENDE,BELGIUM. | Document URI: | http://hdl.handle.net/1942/17907 | ISSN: | 0138-9130 | e-ISSN: | 1588-2861 | DOI: | 10.1007/BF02017105 | ISI #: | A1988R736000010 | Category: | A1 | Type: | Journal Contribution |
