The official time slot for the quantitative units library review is now over. Please don't let this fact prevent anyone from continuing any discussions you consider useful or illuminating. Even late reviews have some time, since it will take me a bit to digest the review comments enough to produce a thorough review results report. I'll continue to watch for any further posts while I'm working on the report. My thanks to Matthias and Steven for their work on the submission and their work during the review. Thanks also to all the people who gave opinions and full reviews during the process. The list is long enough that even listing you all will take some effort. John Phillips Review Manager
