NEW YORK --

Barnes & Noble

(BKS) - Get Report

Chairman Leonard Riggio has expressed interest in buying out the company's consumer-bookstore chain,

The Wall Street Journal

reported, citing people familiar with the situation.

Riggio is Barnes & Noble's biggest shareholder and his interest, though so far tentative, raises the prospect that the company could be split in two, the

Journal

noted. It would mean that Barnes & Noble's retail stores would be taken private, and be separated from the company's college-store chain and its Nook business, the

Journal

said.

Riggio could make a formal announcement this week, one of the people told the newspaper.
