The database contains all data published prior to 1991, in all standard photometric bands from UV to IR. The database contains also some global quantities as, for instance, total magnitudes and color indexes. PACS 98.50 - Galaxies: extraglactic objects and systems (by type). PACS 95.75.De - Observation and reduction techniques: photography and photometry. PACS 95.85- Astronomical observations. Introduction.- Multiaperture multiband photoelectric photometry (MMPP) has been a common practice since 1937 and large amounts of data have been collected by more than 400 different groups of observers (see the catalogues [1-3]). Unfortunately, due to the lack of homogeneity and standardization, as well as to some factors intrinsic to the nature of the data, the bulk of MMPP data is still mostly unexploited, thus preventing from reaching some targets of the highest astrophysical relevance. Indeed, even though CCD photometry is becoming the most effective technique to obtain reliable photometry of galaxies [4], MMPP still keeps its unique role in some applications. In particular: 1) Several active galaxies have been observed almost uninterruptedly over the past fifty years. Therefore MMPP is the only approach to study long-time scale variability in the nuclear regions. (*) Paper presented atthe V Cosmic Physics N~tional Con~rence, S. Miniato, November 27-3O, 1990. 1097
