Developing programs of new directions of work with readers in the changing sociocultural conditions is an actual orientation of domestic librarianship policy. The results of studies undertaken in order to reveal modern trends in the service system of SPSTL SB RAS showed, in particular, the growing request for belletristic and mass literature on the part of readers. This tendency of changing information needs deserves more profound study for to perfect both the servicing system and the technology of building the library stock.The object of the local study, undertaken by the authors of this article, is one of the segments of the large stock of belletristic and mass literature stored in SPSTL SB RAS - the collection of scantily used editions (FMI). Today, FMI is an ever-growing collection of publications that has its own reader, but still is not in demand enough.Our goal was to use the methods of comparison, analysis, synthesis and observation for to consider the relevance of this collection, its place in the system of other library collections, as well as to identify opportunities to realize FMI potential in meeting new readers' needs.The involved theoretical material and the analysis of practice allowed the authors to assert that one of the main causes of unsatisfactory rate of this collection usage are organizational and technological contradictions primarily laid at the bottom of its functional capacity, which prevent providing integrity of its managerial system. Increasing the efficiency of FMI use could be facilitated by bringing it closer to the reader “physically” and reflecting the content of the collection in readers' catalogs.
