 In a letter dated October 7 , 2005 , Kaczynski offered to donate two rare books to the Melville J. Herskovits Library of African Studies at Northwestern University 's campus in Evanston , Illinois , the location of the first two attacks . The recipient , David Easterbrook , turned the letter over to the university 's archives . Northwestern rejected the offer , noting that the library already owned the volumes in English and did not desire duplicates .
