FOR decades, even after it was renamed and relocated from its original home at Radcliffe, the Columbia Publishing Course seemed unchanging, a genteel summer tradition in the book business, a white-glove six-week course in which ambitious college graduates were educated in the time-honored basics of book editing, sales, cover design and publicity. Not this summer.

With the e-book revolution upending the publishing business, Madeline McIntosh, the president of sales, operations and digital for Random House, stood at the lectern on the opening day in June, projecting a slide depicting the industry as a roller coaster, its occupants frozen in motion at the top of a steep loop.

“You might be wondering if this is the moment where we’re at,” Ms. McIntosh, a tall figure in a slim navy dress, said with a smile, as dozens of students with plastic name tags hanging around their necks watched raptly.

So the summer session began with a focus on “The Digital Future.” Students were schooled in “Reinventing the Reading Experience: From Print to Digital” by Nicholas Callaway, the chairman of a company that produces book apps for children. Managers from Penguin Group USA explained how to master “e-marketing,” and a panel of digital experts talked about short-form electronic publishing — not quite a magazine article, not quite a book — which is so new, the genre doesn’t really have a name.
