59. A system for storing documents tracked on behalf of a plurality of organizations, the system comprising: a host system having a processor system, volatile memory, and non-volatile memory; the non-volatile memory including at least one machine readable medium carrying one or more sequences of instructions which when implemented causes the processor system to implement a method comprising: receiving at a host system, a document to store on behalf of a first organization; receiving a tag for storing in association with the document from a client machine; storing in a storage accessible to the host system, the document in association with the tag, the document being stored to document management storage; and associating by the host system, the document in the document management storage with a unique identifier; the host system storing one or more machine instructions, which when implemented cause the host system to perform at least an allowing of a level of access to the document to be granted to multiple users that are members of the first organization, the level of access allowing a plurality of users to at least edit the document, and store the document that was edited on the host system as a master copy of the document; wherein the document stored in the document management storage and copies of the document are tracked using a portion of a database limited to information of the first organization; associating by the host system, the document with one or more of a plurality of document types chosen from a list of document types, each of the document types including one or more properties associated with a list of properties, each property describing one or more characteristics associated with the document type that is associated with the document; and receiving values for one or more search fields, the one or more search fields being different from the tag, the document types, and the properties; and the one or more search fields including at least a field for an author of the original document, a name of a workspace, and a document format.
