Positive impact!AsOrganic & Biomolecular Chemistry(OBC) enters its fourth year of publication, 2006 is shaping up to be a promising year. 2005 proved to be very successful forOBC. The quality, and international authorship and readership reflected in the journal's first impact factor of 2.2.We would like to thank all of our authors, referees and readers for their support forOBCand we look forward to your continued support for years to come. Thanks are also due to the editorial and advisory editorial boards who have worked well alongside the editorial staff to promoteOBCand to help attract some of the very best work to the journal.Indeed these are exciting times for organic chemistry in all its forms. Organic chemistry has proved its worth with the Nobel Prize in Chemistry 2005 being awarded to Yves Chauvin (Institut Français du Pétrole, France), Robert H. Grubbs (California Institute of Technology, US) and Richard R. Schrock (Massachusetts Institute of Technology, US) for their work in the area of metathesis.1The 2004 impact factors, released by ISI®in June 2005, showed an impressive average increase of over 10% for RSC journals. Calculated annually, ISI®impact factors provide an indication of the quality of a journal. They take into account the number of citations in a given year for all the citable documents published within a journal in the preceding two years. It is worth noting that together with ACS Publications, journals from RSC Publishing have the highest median impact factor among publishers in the chemical sciences (Fig. 1). This encouraging statistic demonstrates the recognition and status that researchers place in Society-published work.Median impact factor in the ISI®core chemistry categories.
