The Impact Factor for the International Journal of Molecular Sciences (IJMS) for 2012 is only slightly changed. According to the newly released 2012 Journal Citation Reports® Science Edition (Thomson Reuters, 2013), the new Impact Factor for the IJMS is 2.464 (down from 2.598). However, the 5-Year Impact Factor increased to 2.732 (from 2.617). We see the main reason in change of the 2-Year Impact Factor in the longer delay for citations to happen. While the 'Cited Half-life' was of 2.6 (years) in 2011, it increased to 2.8 in 2012. 'Cited Half-life' indicates the median age of cited materials, i.e. from the citations in 2012, 50% are to papers that were published more than 2.8 years ago. The amount of citations to the IJMS is still on a strong growth path (+68%). The IJMS now ranks 48/152 (Q2) in the category 'Chemistry, Multidisciplinary'.
