In what formats are Les Feldick's past Bible teaching programs available?

Les explains that all the past programs going clear back to Genesis are available on six-hour-long videotapes. He adds that the same material has also been dubbed over into audio and transcribed into print as little corresponding books. He tells viewers that if they are interested in any of that material, they can drop the ministry a line or call. He also mentions a free quarterly newsletter, which requires a name and address, and notes that the mailing list is private, not used for fundraising, and not sold or given to anyone else.
