The thesis examines certain aspects related to digital library collections: the history of their existence and modern trends connected with the need for high-quality integration into the rapidly growing quantitative, chaotic informational web space of scientific value and structured documents. It is substantiated the importance of using library classification systems and subjecting in this process. The synthesis of the provided tools can supply the creation of a systematization subject model in the elaboration of a set of object-thematic sections for the presentation of documents of digital library collections. It is substantiated that the information system should provoke a greater degree of cognitive activity than traditional strategies to improve searches that leave users within the «paradigm of the search window». The functionality of the proposed scientific and methodical principles for providing thematic access to the resources of the Vernadsky National Library of Ukraine electronic library «Ukrainica» is tested. Implementation of this ontology will provide the creation of an interpretative semantic layer between user requests and resource documents.
