The IJR is 30!

The IJR is celebrating its 30th birthday! The first issue was published on May 1, 1978. In his first Editorial, the first Editor-in-Chief, Professor G. G. Haselden, University of Leeds, UK, spoke about the spirit, concept, and aims of the new Journal. They are still the same but the size, worldwide distribution, and the IJR's international reputation and scope have grown tremendously since its early years. For instance, the citation impact factor rose from 0.418 in 2000 to 0.936 in 2006 and the IJR is now ranked 26th out of 106 journals in the domain of mechanical engineering and 14th out of 42 in the field of thermodynamics. Moreover, whereas in 2005 we had 125 000 downloads of full text IJR papers via ScienceDirect, since then an exponential increase in this number has been observed: the figure rose to 258 000 in 2007.
