Health and Human Services Secretary Otis R. Bowen, responding to congressional demands, removed a cap on the number of AIDS education booklets members of Congress can obtain and send to constituents, officials said yesterday.

More than 3 million copies of the 36-page report on acquired immune deficiency syndrome by Surgeon General C. Everett Koop have been requested by 17 House members in the past month, HHS officials said.

The Public Health Service had limited distribution of the booklet to 1,000 copies per congressional office, but that policy came under fire last month when Rep. Gerry E. Studds (D-Mass.) requested and received copies for all 268,000 households in his district.

Studds, an acknowledged homosexual and leading advocate of AIDS education on Capitol Hill, had urged his House colleagues to make similar requests, but Rep. Patricia Schroeder (D-Colo.) and several others who did were turned down.

Public Health officials had said filling the congressional orders would have been impossible because the department had not budgeted for such widespread distribution.

But in a policy reversal, Bowen wrote to all members of Congress late last week and promised that "more copies of the report can be made available for your use and we will provide them as expeditiously as possible."

"We had those {congressional} requests pending, and the secretary felt this was another way to get information and education to the public," Public Health Service spokesman James Brown said in explaining Bowen's decision.

The department had sent more than 700,000 copies of the booklet out to individuals and organizations requesting them, Brown said. The 1,000-copy limit is still in effect for non-congressional organizations and offices, he said.

Brown said he did not know specifically where the money to pay for the extra copies would come from, but added, "I'm sure that we'll be able to find the money." He said he did not know how much the extra copies would cost or when they would be ready.

Studds, in a telephone interview from Cape Cod, said he was pleased lawmakers could now get the booklet for all their constituents, but feared Bowen's decision was an attempt by the Reagan adminstration to avoid conducting a national mailing of AIDS education materials.

But Brown said Bowen's decision to lift the cap on the surgeon general's pamphlet had nothing to do with whether the administration will conduct a national mailing.

Public Health officials are contemplating a national mailing, but with a booklet that is smaller than the surgeon general's report, he said.
