Texts Undergo Raise in Cost

Prices of textbooks published by Knopf. McGraw-Hill, and Rinehart will take an immediate increase of ten to 20 percent, local bookstores announced yesterday. This is part of a general trend that has been in progress ever since the war.

"Many of the textbooks are going up," Mark Kramer of the Harvard Book Store said yesterday. "It may be an increase in the price of labor and materials. It is mainly the price of paper."

Some typical examples of the latest round of price hikes are: "A History of England," by Felling, used in History 142, upped from $5 to $6; Allen's "Heating and Air Conditioning" used in Engineering 280, which jumped from $5 to $6.50; "Physiological Psychology," by Morgan and Stellar, used in Psychology 122, from $5.50 to $6.
