Harvard is assigning "two extremely dirty books" to its students. This discovery was announced Wednesday by Rep. Kathryn E. Granahan (D. Pa.), chairman of the Postal Operations Subcommittee. Regretfully, she failed to specify the particular books involved.

The attack on the University's taste in course reading occured while the committee was hearing testimony on a similar lapse by Boston University.

The subcommittee reavealed that a B.U. English course on "Representative American Writers" listed Henry Miller's banned novel, "Tropic of Cancer" among four books of which students were required to read one.

B.U.'s Dean of the College of Liberal Arts and head of the English Department quickly issued a statement explaining that the instructor had emphasized that Miller's novel could not legally be bought in Massachusetts.
