In recent years, the concept of an impact factor has now evolved to explain both journal and author impacts. Alongside these developments, bibliographic analysis of citation data has also gained popularity, providing an increasingly detailed insight into the past and future trends of academic research and journal publishing. Although Contact Dermatitis has had an impact factor since the early 1970s, the journal’s score rose dramatically after 2002 reaching to 2.701 in 2005 and is currently sitting at 2.446. There were presumably 2 reasons for this remarkable increase in such a short period of time. First, certain categories of articles were no longer being counted in the denominator upon which the impact factor calculation is based. Second, it can be assumed that this recent upsurge also reflects the rising importance of modern contact dermatitis research, not only for clinicians, but also for the wider community of scientific researchers and general citizens. As such, it remains to be seen what the next 30 years of impact factors will bring for the field of contact dermatitis.
