Since the closing date for material included in the FK4 many new positions of fundamental stars have been published, most of them observed differentially. I think in these few minutes it is neither desirable nor necessary to present alist of all these catalogues. We are mainly interested in recent observations which allow us to improve the fundamental system of positions and even more the system of proper motions.
