From a tech, not legal, publication, but this article offers some good advice:
"Many large projects generate a lot of documentation. Depending on the type of project, sometimes there are literally hundreds or even thousands of documents produced. One often overlooked aspect of a large project is the need to organize and manage all of the documentation. More and more companies have document management tools in place to help, but you still need someone to be responsible for the overall document management process.
"The first step in this effort is to establish a document repository. This could be a tool-based repository or a simple folder structure. There can be a lot of work associated with establishing a good repository that makes it easy to organize, store, and retrieve documentation. Much of this work can be assigned to a Repository Librarian."
