Researchers have been, for the past decades, facing an ever accelerating growth of all kinds of scientific and technical information. With the advent of electronic technologies and especially the Internet the data flow has turned into a deluge. This is affecting especially interdisciplinary fields. It has gradually become impossible to even follow the distribution of relevant information let al...

Journal classification systems play an important role in bibliometric analyses. The two most important bibliographic databases, Web of Science and Scopus, each provide a journal classification system. However, no study has systematically investigated the accuracy of these classification systems. To examine and compare the accuracy of journal classification systems, we BLOCKIN

BACKGROUND The usefulness of Google Scholar (GS) as a bibliographic database for biomedical systematic review (SR) searching is a subject of current interest and debate in research circles. Recent research has suggested GS might even be used alone in SR searching. This assertion is challenged here by testing whether GS can locate all studies included in 21 previously published SRs. Second, it e...

OBJECTIVES The aim of this study was to examine location of systematic reviews of test accuracy in five specialist review databases: York CRD's DARE and HTA databases, Medion (University of Maastricht), C-EBLM (International Federation of Clinical Chemistry), and the ARIF in-house database (University of Birmingham). METHODS Searches were limited to the period 1996-2006. Test accuracy reviews...

In a bibliographic database, the main task is not to find exact duplicate records, rather it is to find those that refer to the same work but differ in some manner. Differences are typically due to inaccurate or inconsistent data entry. One such detection method was developed by Ridley [Ridley 92] who adopted a two stage technique. First, all records in a database were assigned a number generat...

Scientific journals play an important role in the transfer of scientific information, and international visibility is a prerequisite for fulfilling this role.

These journals have an unfavourable starting position because of the small number of manuscripts receiv...
