Embodiments relate to methods and systems for building representations of related subjects. The representations may include a plurality of nodes, each being associated with a subject. Users may be able to access records and/or source documents related to a plurality of subjects and add or modify node characteristics based thereon. Users may be able to perform an interaction and/or modification related to a record page. Other users (e.g., users connected to the record page) may be notified of such interaction and/or modification.
