Traffic was once again heavy on the RePEc sites in April 2004: 337,530 file downloads and 1,519,622 abstract views. This pushed totals since we started counting to 7,811,693 file downloads and 50,577,391 abstract views. Yes, this is over 50 millions. A major event this month is the 16% increase in the number of registered authors, and the participation of CESifo. And here are the traditional thresholds that have been passed during the month, documenting the continued growth of RePEc: 50000000 cumulative abstract views 225000 research items listed in RePEc 75000 working paper abstracts 70000 items listed in profiles of registered authors 30000 working papers with extracted references 30000 items with citations 15000 working papers with citations 15000 journal articles with citations 4500 registered authors -- Christian Zimmermann FIGUGEGL!
