I have counted for the well known Journal Nature ("This is a RoMEO
yellow publisher") the ORBI deposits since publication date 2002:R = Request copy (no full text = NO OPEN ACCESS forever or author's dead + 70 years whichever comes first) F = Full text PP/R-AP/F = 2 files, one publisher postprint with Request button, one author postprint full-text 2010 R 2009 F 2008 2 R, 1 PP/R-AP/F 2007 2 R 2005 6 R 2004 2 R, 1 F 2003 1 R, 1 F, 1 PP/R-AP/F 2002 3 R Summa summarum: 22 "Nature" articles, only 5 full-text. This is in no way a success for OA. The Liege "mandate" is worthless. Because authors tend to deposit publisher's PDFs with request button (which is, as I have shown several times, evil) instead of the preprint or (in the Nature case after an embargo of 6 months) postprint the request button is against OA.
