The article presents new information capabilities of electronic bibliographic resources using the example of network union catalogs and products of popular recommendation bibliography posted on the websites of central regional libraries of the constituent entities of the Russian Federation. During the transition to the digital environment, they undergo major changes, leading to an expansion of the information potential of their use in library practice. It is noted that despite the advantages of online bibliographic resources, there are a number of features that reduce the effectiveness of their use in information and bibliographic retrieval. There are differences between the proposed models for the development of digital bibliography and the real state of network resources of union catalogs and popular recommendatory bibliography. Ways to overcome existing problems are determined. The possibilities of integrating bibliographic resources in the digital environment are considered.
