The New York Times is planning to eliminate about 100 editorial positions this year, underlining the quickening pace of lay-offs at newspapers as the economy slows and advertising comes under pressure.

Bill Keller, the Times’s executive editor, informed employees of the planned cuts at a meeting on Thursday and said they would come through a combination of attrition, buy-outs, and possibly lay-offs. The Times noted that its current editorial staff – 1,332 – was the highest in its history.
