June 24, 1975 Dr. Robert M. Baer METADATA Corporation P. O. Box 746 Mill Valley, Cal. 94941 Dear Dr. Baer: In response to your letter of June 11, I have enclosed a copy of our latest SUMEX-AIM brochure. This gives an up-to-date list of projects utilizing the SUMEX-AIM resources. The question of ownership and availability of listings should be taken up directly with the principal investigator of the project in which you are interested. We would be glad to help in any way we can. The systems software and supporting application program I assune are not the subject of your concern. They are mainly under license from vendors and arrangements for their use or for listings would have to be made with the appropriate vendor. Here again let us know if there is any service we can provide. Sincerely, Elliott Levinthal cco: C. Brewer
