  The second version of the catalog contains information about 275 stars of
different types. During the time that has elapsed since the creation of the
first catalog, situation fundamentally changed primarily due to the significant
increase of accuracy of magnetic fields (MF) measurements. Up to now global
magnetic field were discoverd and measured in stars of many types and their
behavior partially was studied. Magnetic behavior of Ap Bp stars is the most
thoroughly studied. The catalog contains information about 182 such objects.
The main goals for the construction of the catalog are: 1. Review and summarize
our kowledge about magnetic behavior of different types of stars. 2. The whole
data are uniformly presented and processed which will allow one to perform
statistical analysis of the variability of the (longitudinal) magnetic fields
of stars. 3. The informations are presented in the most convenient form for
testing different theoretical models of different kind. 4. The catalog will be
useful for the development of observational programs.
