259 Bulgarian Journal of Science and Education Policy (BJSEP), Volume 8, Number 2, 2014 THE SUCCESSFUL SCIENTIFIC PERIODICALS: CONTEMPORARY ISSUES 1) B. V. TOSHEV Abstract. The new scientific results should be published. However, the scientific result will be lost in inappropriate choice of the media in which is expected to appear. The world periodicals are developed in two levels, parts of the World System of Abstracting, Indexing and Evaluation, WSAIE. This system is just the body of the world science. The first level consists of the primary research journals. After careful inspection these journals should be accepted for covering in secondary research sources – the latter build the sec- ond level of the system. Journals, which are not presented in secondary re- search sources, are considered as marginal and the submission of manuscripts to such journals is not recommended. The second level of WSAIE has an elite part, an American one (Thomson Reuters, Web of Science), and an European one (Elsevier, SCOPUS). The journals of Web of Science are characterized by their impact factor, IF; the journals of SCOPUS are characterized by their im- pact rank, SJR – these journals’ scientometric characteristics are entirely equal in use; no one of them should be favoured in respect to the other. However, these factors characterize the journals, not authors publishing in them; there- fore, these numbers cannot be used neither to compare different scientific ar- eas nor in the personal evaluation of authors' scientific activity. The personal and institutional competencies for research could be estimated by properly use of some scientometric variables. The most important of them are considered.
