As it continues to reinvent itself, Borders said this morning that it is entering the online textbook market, teaming up with Alibris to launch Borders Textbook Marketplace. The site, at borders.com/textbooks, will offer 1.4 million new and used textbooks and will buy back student texts. Borders two major competitors, Barnes & Noble and Amazon, both have active online textbook operations.

The company also announced that it has completed the sale of Paperchase to the U.K. investment firm Primary Capital Limited for $31 million. Borders, which announced the deal last week, is using the proceeds to repay debt.
