An assistant to Attorney General Richard G. Kleindienst '47 will speak at today's dedication of Roscoe Pound's personal library at the Association of American Trial Lawyers at 20 Garden St.

Pound was Dean of the Law School from 1916 to 1937. The library, which he accumulated up to his death in 1964, will be dedicated at a ceremony at 11:00 a.m.

Roger C. Cramton, Assistant Attorney General for the Office of Legal Counsel, is scheduled to fill in for Kleindienst, who was the original speaker. Kleindienst was detained in Washington by official business, his office said yesterday.

Harvard SDS had planned to picket today at the Trial Lawyers building in protest of Kleindienst's visit. Katherine J. Moos '75, a co-chairman of SDS, said yesterday that the organization would probably not picket against Cramton, although the protest was to have been, in Moos's words, "the policies Kleindienst represents ... not against Kleindienst as a person."

Cathy Bentise, of the Trial Lawyers Association, said yesterday that the visit of Kleindienst was not intended to be political. She said that the Association has had many well known law figures as guests in recent years, regardless of their political affiliations--among them, former Attorney General Ramsey Clark and former Chief Justice Eari Warren.
