Just wanted to let you all know that Google Scholar recently released their 2014 Metrics. Google lists the top 20 library science publications based on h5-index. Coming in at number one is the Journal of the American Society for Information Science and Technology with an h5-index of 56. The h5-index is the h-index for articles published in the last 5 complete years. Usually the h-index is used to measure a specific author’s impact, but Google Scholar has applied this measurement to journals as well (most databases use the Journal Impact Factor). Google measures the h-index of a publication by determining “the largest number h such that at least h articles in that publication were cited at least h times each. ” For example a journal with six articles that have been cited 20, 15, 11, 10, 9, and 8 will have an h-index of 6. Here are a few data visualizations I made and a reading list for more info about Google Scholar’s metrics.
