The English-Philosophy Building, known on campus as EPB, has been home to these two humanities departments and the Department of Linguistics since its construction, and to the Department of Rhetoric since 1970.
From City Guide: Iowa City by Jan Weissmiller:
Just west of the Main Library is the English-Philosophy Building. From the time it was built in the late 1960s until 1997 it housed the Workshop. Its gray, utilitarian classrooms were the location of much beauty and heartbreak. Its small lounge on the third floor was the space where visiting writers for all those years endured the question and answer sessions that take place the morning after heralded readings. I have heard Robert Hass, Louise Glück, James Tate, James Merrill, John Ashbery, W. S. Merwin, Seamus Heaney, and Helen Vendler all answer questions in that room. Brilliant questions from brilliant students as well as questions such as, “Do your ideas just come to you or do you make them up?”
