The New York Times Co. (NYT) said Tuesday it would cut 500 jobs, or about 4 percent of its work force, as part of an ongoing effort to reduce costs. The reductions come atop another 200 jobs that were cut earlier this year.

The Times said it expected 250 jobs at its main newspaper group to be affected, which includes the Times, the International Herald Tribune and the online operation of the Times. Of those job cuts, about 45 will come from the Times' newsroom, the company said in a statement.

Another 160 jobs will be cut from the Times' New England operation, which includes The Boston Globe (search) and the Worcester Telegram & Gazette (search) and Boston.com. The company did not provide a breakdown of those job cuts other than to say that 45 newsroom jobs would be cut at The Boston Globe.

The announcement came on the same day that The Philadelphia Inquirer (search) and its sister newspaper said they'll eliminate a combined 100 newsroom jobs through buyouts and layoffs if necessary because of lower circulation and revenue. The Inquirer plans to cut its editorial staff by 15 percent from 500 to 425, while the Philadelphia Daily News will cut its editorial staff 19 percent, from 130 to 105.

Both newspapers are published by Philadelphia Newspapers Inc., which is owned by Knight Ridder Inc. (KRI), the nation's second-largest newspaper company.
