Abstract: A document construction and management system is described. In one embodiment, documents are assembled by combining one or more modules. In one embodiment, the modules are combined according to one or more construction rules. The modules can be provided to a number of subscribers, each subscriber having one or more users. Access to each of the modules can be controlled on a subscriber basis and/or on a user basis based on different users or user classes. When new modules or new versions of an existing module are added to the database of available modules, access to the new module or version can be restricted until the new modules or versions have been reviewed and accepted. During the review period, the previous version of the module is made available to users for construction of documents. In one embodiment, one or more access rules are used to control which modules are available to which users. In one embodiment, search rules are provided to facilitate searching for a desired module.
