These two recent OC catalogues maybe of interest too:
Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)
http://cdsarc.u-strasbg.fr/viz-bin/Cat?J/A%2bA/438/1163
109 new Galactic open clusters (Kharchenko+, 2005)
http://cdsarc.u-strasbg.fr/viz-bin/Cat?J/A%2bA/440/403
They were made by searching the All-sky Compiled Catalogue of 2.5 million stars (Kharchenko 2001)
