Welcome to JBCS
|
|
With this issue, the Journal of the Brazilian Chemical Society starts another year, its twenty-first. Again, the results from the last year are positive and the perspectives are encouraging. Looking backwards, we see that the impact factor for this journal has increased from 0.44 in 1996 to 1.43 for 2008. The number of manuscripts submitted has gone from 304 in 2004 to 889 in 2009. This is a number that puts JBCS on the level with other important chemistry journals. This significant increase has led to a change in the periodicity of JBCS. The first volume of JBCS, in 1990, published 138 pages in three issues. Volume 10, published in 1999, had 511 pages in six issues. Finally, volume 20, in 2009, published 1944 pages in 10 issues. For 2010, considering that the number of submissions continues to increase, 12 issues will be published. This is, certainly, a great step for our journal, but it will permit better agility in publication of already accepted manuscripts and will contribute to a desired reduction in processing time.
