HERNANDEZ GARCIA, Yoscelina; KLEICHE DRAY, Mina  e  RUSSELL, Jane M.. Methodological approaches to identify and describe Mexican chemistry research in bibliographic databases. Investig. bibl [online]. 2013, vol.27, n.59, pp.35-66. ISSN 2448-8321.

The varying visions of a particular research field in diverse information sources are a recognized phenomenon in bibliometric and scientometric studies. The purpose of this paper is to provide an understanding of the impact of using distinct information sources for the identification and description of a scientific field in a specific context, in this instance the field of chemistry in Mexico. We use both international and national sources specializing in or related to chemistry, as well as suitable multidisciplinary services, including Web of Science (WoS), Chemical Abstracts Service (CAS), PERIÓDICA and CAB Abstracts (CAB) for 2000-2004. Using an original methodology involving the construction of appropriate search strategies for each database and processes for the normalization, the authors compare and analyze the scientific production extracted from the distinct bibliographic databases, showing that the definition of the scientific field under study depends on the information source consulted. Our findings reveal the impact of a given database structure on search results. In the PERIÓDICA index, scientific articles are concentrated in 37 journals (44%), while in international journals it is distributed across a large number of titles, 1559 (WoS), 188 (CAB) and 1640 (CAS).
