well, I would start with the microsoft article:

note that it is not limited to vb6, but targeted obviously to that development tool due to the COM-oriented issue.

in short:
  keep the DLL's with 1 main public engine class, and let that offer members that give access to the collections and items of your data and processes.
  do this all the time the same way, so you can reuse the code a maximum
