The current research expands on past research in ranking of information systems journals. A new metric, the gc-index, derived from previous Hirsch family of bibliometric indices, is introduced. Past indices didn’t take into account the time or size of citations or ignored both. The gc-index expands on the h-family of indices by taking into account both the time the research has been in existence, via year, and the amount of impact, via citation count. The metric is used to update IS journal rankings. The metric is compared with the previous indices that take into account the size (g-index) and time (hc-index).
