Over the past decade, the issue of uncontrolled growth of unsystematic information in Internet has remained acute for the scientific community. The problem of finding relevant information related to the distribution and autonomy of scientific information resources remains. A priority in the field of centralized access to the key scientifically significant sources of information is the creation of a united information space (UIS). The study aims to identify the main models to form systems integrating distributed information resources, and as a result to determine the structure of UIS formation in a research library. Two models were considered and analyzed in the study: a meta-aggregator and an integrated electronic library. During the analysis, elements, structure and a set of functions for users and employees of a research library are revealed for each model. The study allowed the drawing of the following conclusions:• The choice of a model for the UIS formation depends mostly on the formulation of tasks, the solution of which is the purpose of creating a system, as well as on the technological potential of the organizations involved in the process.•Multifunctionality of the system allows simultaneous use of the above-mentioned formation models.• Adding the element of interactivity to the structure of UIS of the research library will allow timely monitoring of changes in the information needs of scientists, reduction of time, labor and financial costs of both the library and a user. The article presents the criteria for choosing a model. For the first time the optimal effective structure of the UIS in the research library is described.

Based on the analysis of typical scenarios of information servers, the tasks that should be solved when organizing an access control system for distributed information resources are formulated. The possibilities of the Z39.50 technologies as the most suitable for building such a system are considered. Within the framework of this technology, three access control models are discussed, which differ in the degree of integration of information server functions with the Z39.50 technologies.The creation and support of distributed information systems and electronic libraries that integrate heterogeneous information resources and operate in various software and hardware environments requires special approaches to managing these systems. If the resources or data themselves can be managed locally, even for distributed information systems, then the task of managing access to distributed resources cannot be solved within the framework of local administration. The justification of the last thesis can be seen when considering typical scenarios of the information server, which we will describe below
