Abstract. The data in the latest on-line version of the Wide-Field Plate Database (WFPDB) have been analyzed. The total number of observations in WFPDB from the archives of more than 100 professional instruments that operated in the period 1885-1999 has reached nearly half a million. The characteristics of the two main parts of the database - the Catalogue of Wide-Field Plate Archives (CWFPA) and the Catalogue of Wide-Field Plates (CWFP) - are described. The inclusion recently in WFPDB of digitized images of the plates, as well as some new possibilities for data search are discussed.
