The article is dedicated to the problem of forming the Common Digital Space of Scientific Knowledge (CDSSK) content. CDSSK is a structured information environment that ensures the formation, storage, and provision of multi-species digital scientific information as linked data, the accuracy of hich is confirmed by the scientific community. CDSSK represents a combination of universal and thematic subspaces that reflect heterogeneous objects related to scientific knowledge. The object can be a digital copy of a physical entity (for example, a book, museum object, archival document, etc.), a database, information about an event, organization, scientific fact, etc. The article presents information about the current state of work in the field of forming the CDSSK and discusses issues related to the reflection of Library Science as a scientific field within the CDSSK. A variant of the structure of the subspace “Library Science” is proposed. It includes classes of objects such as “key concepts”, “persons”, “publications”, “documents”, “organizations”, and “scientific events”. The objects attributes of these classes and various types of relationships, including those with objects from other subspaces, are considered.
