The Practicing Law Institute is a non-profit organization that produces legal reference publications and continuing legal education programs. This librarian has found their programs to be generally very well put together and informative.
As a non-profit they are committed to providing many CLEs that target the needs of attorneys providing pro-bono services. Many of these CLEs are available on their website free of charge. While the CLEs are mostly conducted in New York and California many are registered for credit in Oregon.
