We routinely use Network drives. We have our libraries and folders copied nightly into a read only folder which are accessible to all users, but write protected (and you get a “locked” warning when you first open it). Then if someone wants to modify, they need to open the read-write parent copy and add or edit the records. The only pain, is that if someone has it already open, you don’t know whom. We have a realtively small group of users (5-10) so a quick email can suffice.
