Different types of experimental data require different procedures for collection and for evaluation. I am more directly concerned with the evaluation of the masses of nuclei, more precisely their atomic masses: the 'Atomic Mass Evaluation' (AME). And also, directly connected to the masses, by the properties of ground states and long-lived isomers of nuclei, their spins, half-lives, excitation energies, and decay modes, called the NUBASE evaluation. Masses as well as nuclear and decay properties have in common requiring 'horizontal' collection and evaluation. Here I describe the most prominent features of the AME, the reasons for its complexity, and how they are faced and solved. The masses of still unknown nuclides we estimate from the regularity of the surface of masses. We finally succeeded in having AME and NUBASE co-ordinated and published for the first time together in December 2003.
