Abstract: Techniques are provided for document management, which may occur at a physical document, at a remote location, or at a combination thereof. Document management at a physical document may include sensing a state of a document, generating a signal representing the document state, determining the document state based on the signal, and generating a wireless message representing the document state. Document management at a remote location may include storing non-physical versions of documents, receiving state data for physical versions of the documents, associating the state data with the appropriate non-physical versions, and managing access to the non-physical versions and the state data.
