"Some publishers are being very honest and very forthright and not trying to milk the situation," he said. "Other publishers are taking their books out of print as soon as possible, it seems."

However, faculty may not be willing to pay the higher prices.

Steven R. Singer, director of communications and public affairs at the Kennedy School of Government, said that high permission fees make him reconsiderusing some material.

"I teach a class were we use course material,"Singer said. "I have occasionally not includedmaterial that was marginal in value because ofcost."

"Generally, if it's important material, youhave to use it," he added.

Witt said that he informs professors if theirsourcebooks are going to be unusually costlybecause of length or permission fees.

"If an individual item comes in and it's muchhigher than what I consider to be normal, I'llcall the professor," he said. "There comes a pointwhen faculty aren't going to pay the high prices.The ones [articles] that are most expensive theywon't use."

The length of the sourcebook also makes adifference in cost, Witt said.

"For a course like A-12, which has a very largesourcebook, their book is very expensive," Wittsaid. "Some faculty make the size of thesourcebook smaller [to save money]."

Witt said most sourcebooks for Core classescost between $40 and $60.

Across the nation, the average costs forsourcebooks is $16, according to the O'Donnellreport
