    ABSTRACT:: Personal computers are superior to timesharing systems in
               many ways, but they are inferior in this respect: they make
               it harder for users to share files. A local area network
               provides a substrate upon which file sharing can be built;
               one must also have a protocol for sharing files. This report
               describes Leaf, one of the first protocols to allow remote
               access to files.

               Leaf is a remote file access protocol rather than a file
               transfer protocol. Unlike a file transfer protocol, which
               must create a complete copy of a file, a file access protocol
               provides random access directly to the file itself. This
               promotes sharing because it allows simultaneous access to a
               file by several remote users, and because it avoids the
               creation of new copies and the associated
               consistency-maintenance problem.

               The protocol described in this report is nearly obsolete. It
               is interesting for historical reasons, primarily because it
               was perhaps the first non-proprietary remote file access
               protocol actually implemented, and also because it serves as
               a case study in practical protocol design.

               The specification of Leaf is included as an appendix; it has
               not been widely available outside of Stanford.
