Referring to the Congressional decision to withhold the funds as a ''back door'' method of censorship, Mr. Miller said Congress could not direct the library to cease production of a particular publication, but signaled its intent by specifying the amount of money to be witheld.

Other plaintiffs in the case include the Blinded Veterans Association, the American Library Association and Playboy Enterprises Inc.

Representative Chalmers P. Wylie, an Ohio Republican who led Congressional opposition to the Braille Playboy, said he would not decide whether to appeal today's verdict until the written decision was handed down, according to his press secretary, Mark Sharp.

Nancy Bush, a spokesman for the Library of Congress, said library official would also wait for the written decision before deciding on an appeal.

Until last December, Playboy had been published monthly in Braille since 1970 under the National Library Service for the Blind and Physically Handicapped. None of the other 35 magazines published in Braille was dropped. Playboy was the library's sixth most popular publication, Mr. Miller said.
