In the last few days, Edward Elgar books published between 2009 and the present have been added to Elsevier's Scopus citation index. I reported a couple of years ago about the Web of Science adding a book citation index that would at first feature Elgar books. Some Elsevier book series are already included in Scopus, but I'm surprised that they would add Elgar's books before doing a more comprehensive selection from Elsevier. Elsevier doesn't publish much in the area of economics but I just checked a couple of recent books from their list and they aren't included in Scopus. Anyway, this is a further narrowing of the gap in coverage by the three main citation index providers: Google, Thomson Reuters, and Elsevier.
