(Reuters) - Activist investor Sandell Asset Management Corp wants Barnes & Noble (>> Barnes & Noble, Inc.) to try to sell itself again, saying the bookstore chain will benefit from a new owner, the Wall Street Journal reported on Monday.

Barnes & Noble could attract a bid of more than $12 (9.2 pounds) a share, the Wall Street Journal reported, citing a letter from Sandell.

Based on Monday's closing share price of $7.10, Barnes & Noble's market value is about $515 million.

John Malone's Liberty Media Corp (>> Liberty Media Formula One) proposed buying Barnes & Noble for $1.02 billion in 2011, but ended up investing in preferred shares it could convert into a stake later.

In 2014, Liberty sold almost all its stake, ending a nearly three-year bet that the retailer would emerge as a dominant seller of e-books. http://reut.rs/2uUsEcY
