The detection of Am and Ap stars is possible in various photometric systems. Those most suitable for this purpose are certainly the uvbyβ (Strömgren 1967, Cameron 1967), the Barbier Morguleff system completed by Gerbaldi (1972, 1977) and the Geneva system. It seems important to me that the Am and Ap stars should be detected with a system which also allows one to classify normal stars, and to obtain quantitative information about metallicity or other peculiarity. The Geneva system satisfies both these criteria and numerous Am (about 400) and Ap (about 250) stars are in a catalogue prepared on magnetic tape by Rufener, which follows the one published in 1976 (Rufener 1976).
