ILCA publishes "Resources for Lactation Consultants" with many, many videos
listed and their sources.  Back issues of the JHL contain helpful reviews of
videos.
Good luck - there are many good ones out there and more being produced each
year.

Linda Smith, BSE, FACCE, IBCLC - first editor of ILCA's "Resources" which
actually started in Ohio if anyone wants to be queen of trivia this month.
