Apparently the original site at netnews.org that had these online ran into trouble with copyright permission with Lucis Trust. If we have the same trouble here, then please just delete this post. Thanks.
Lucis Trust will let someone check out the books contained in the library there through the mail for 2 months checkout time. I sent off for the information and got the application, but they seemed confused when I asked to get a list of the titles they have available. They also have a training program on hermetics, but they needed me to have previous knowledge of theosophy and hermetics, particularly Bailey's works. I didn't at the time, but I haven't looked back there since.
There is also some free study guides and a study egroup to widen the understanding on a Treatise of Cosmic Fire at http://makara.us/ . Click on Fellowship on Cosmic Fire there.
I think I got them all here, but if I missed any of hers, please let me know, and I will keep looking.
