The index is the first in domestic source study experience in creating reference work on an extensive (over 4000 issues) "autobiographical collection" by S. A. Vengerov. He gives in a single alphabet of names a list of storage units (cases) of the three components of the collection, provides fairly specific information about each of these units separately, reports systematized and updated information on the composition and architectonics of the collection as a whole. The proposed publication will help document the most diverse research on the Russian intelligentsia (mainly the 2nd half of the 19th - early 20th centuries) in all the diversity of its artistic and scientific work. In addition, fixing within the annotations the main bio-bibliographic data on the characters of the "many-sided" collection, it also acquires wide interest as preparatory materials for a universal biographical dictionary - more "hospitable" than existing publications, to ordinary representatives of Russian culture. The index can be useful to historians of science, literature, art, social thought, bibliophiles, local historians, university teachers, graduate students, students, all curious readers.
