Borders bookstores may have a savior. The private-equity firm Gores Group is in discussions to buy more than half of the bankrupt bookseller in a deal that would keep the business running. Borders has been soliciting offers since it filed for bankruptcy in February. Gores, which buys stakes in distressed companies and tries to rehabilitate them, isn't the only bidder on the horizon, though the other potential buyers haven't been named. Interest in Borders has picked up since Liberty Media's recent bid for Barnes & Noble.
