My last two annual reports sounded a theme of continuity from year to year in the number and variety of the papers that we received and the articles that we published and in the pace of our review process. This year, too, many of these elements have differed only slightly from those of past years. In some important respects, though, 2005–2006 has been a significant departure from the years immediately preceding it. For one thing, as detailed below, during 2005–2006 we received a record number of submissions. For another, while we were considering more papers than ever before, we were simultaneously faced with the self-imposed challenge of conducting a separate review process for the November 2006 centennial issue of the Review.
