Hi all-- I've had no problems getting what I need from past Herbertia's from two of the major universities in Texas. Just email the librarian and they will pdf you what you request. They usually reply quickly to your request email, but then it might take them a couple of weeks to send you the pdf articles requested--I'm sure its because they are very busy. Once they know you it gets faster. Debbie Those universities would be Texas A&M College Station and UT Texas in Austin--both have wonderful and helpful librarians.
