This research aims at performing a comparative study between the Brazilian scientific production in Dentistry, from 2000 to 2009 and countries that contribute with at least 2 % of the world's scientific production indexed in the Scopus database. More specifically, we intend to assess the annual Brazilian scientific production by comparing it to the other countries', analyze the Brazilian and other countries' publications in journals with higher impact factors, as well as to highlight the scientific production from these countries and its international visibility, measured by its total and by its average of citations and normalized citation index per year, by comparing the countries, and to compare the index h of such countries. As work procedure, the SCImago Journal and Country Rank was used as source, identifying the group of producing countries in the Dentistry area from 1996 to 2009. From a total of 136 countries, 13 were highlighted as the most productive, each one of them accounting for at least 2 % the worldwide scientific production in the area. The following indicators were raised for each country: number of produced documents, total of citations, self-citations, average of citations per document and index h. We verified that Brazil is the only country in Latin America that is pictured among the most productive ones in the Dentistry area. We observed that Brazil presents a growing visibility and impact in the international scenery, what suggests that its production is constantly consolidating, with Brazilian scientific recognition in the main vehicles of dissemination in the area.

The objective of this study was to make a current diagnosis of the scientific production of Ibero-American researchers on information literacy and information competences during the last four decades. The literature output on information literacy was examined using the techniques of bibliometric analysis and information visualization. The literature considered was that constituted by the articles included in the Web of Science (Thomson Reuters), Scopus (Elsevier), Library and Information Science Abstracts, and Library, Information Science and Technology Abstracts databases. The occurrence of descriptors was analysed using VOSViewer, a program that groups them into clusters and generates a map of their connections. The results showed exponential growth of some 30 % annually between 2005 and 2011, with a mean of 14.45 documents per year. Spain, with 119 documents, was the top producing country, followed by Brazil with 76. The distribution of the more than 500 authors fitted a Lotka-law pattern, and the distribution of the 105 journals fitted the three zones of a Bradford-law pattern. The visualization map showed the 62 descriptors to group into seven clusters. For its centrality, there stood out ''Information literacy'', strongly related with ''Information Science''.
