  Binary star DataBase (BDB) is the database of binary/multiple systems of
various observational types. BDB contains data on physical and positional
parameters of 260,000 components of 120,000 stellar systems of multiplicity 2
to more than 20, taken from a large variety of published catalogues and
databases. We describe the new features in organization of the database,
integration of new catalogues and implementation of new possibilities available
to users. The development of the BDB index-catalogue, Identification List of
Binaries (ILB), is discussed. This star catalogue provides cross-referencing
between most popular catalogues of binary stars.
