Jonathan Bulkeley's reign at barnesandnoble.com proved to be a short one -- 12 months.
The company said Bulkeley resigned to pursue interests in other Internet companies, including European online auction firm QXL.com.
His resignation took effect immediately, and Steve Riggio was named vice chairman and acting CEO, barnesandnoble.com said. Riggio, vice chairman of Barnes & Noble Inc., founded barnesandnoble.com and was its CEO until December 1998.
The New York-based online retailer said it expects to name a new CEO "shortly."
