Washington Post Co. will combine the business section with its front section Monday to Saturday, dropping it as a standalone from its flagship newspaper to save on paper costs. The plan was announced to employees in a memo from four editors today, said Kris Coratti, a spokeswoman for the Washington-based publisher. The changes, effective March 30, also include trimming stock-price listings to a half-page. The actions ‘allow us to save on newsprint, an important objective in these times, the memo said. ‘These moves will allow us to continue providing the features that our readers tell us they most value in the newspaper. Newsprint prices jumped 32 percent in 2008, according to Foex Ltd. in Finland. The Post will also begin running a daily page devoted to local business, rather than a weekly section. The newspaper will run fewer comics in its Sunday print editions, moving some to its Web site, and will eliminate one of its crossword puzzles. Washington Post fell $10.61, or 3 percent, to $344.34 at 4:02 p.m. in New York Stock Exchange composite trading. The shares have declined 12 percent this year.
