Related Party Transactions Disclosure [Text Block]	Note 11. Related Party Transactions MBS Textbook Exchange, LLC Prior to the acquisition of MBS on February 27, 2017, MBS was considered a related-party as it was majority-owned by Leonard Riggio, who is a principal owner holding substantial shares of our common stock, and other members of the Riggio family. See Note 4. Acquisitions. Prior to the acquisition, we had a long-term supply agreement (“Supply Agreement”) with MBS, under which and subject to availability and competitive terms and conditions, we purchased new and used printed textbooks for a given academic term from MBS prior to buying them from other suppliers, other than in connection with student buy-back programs. Prior to the acquisition on February 27, 2017, total purchases from MBS were $92,956 (amount prior to returns which occurred subsequent to the February 27, 2017 acquisition date) and $57,981 for Fiscal 2017 and Fiscal 2016, respectively. Additionally, the Supply Agreement provided that we could sell to MBS certain textbooks that we could not return to suppliers or use in our stores. MBS paid us commissions based on the volume of these textbooks sold to MBS each year and with respect to the textbook requirements of certain distance learning programs that MBS fulfilled on our behalf. Prior to the acquisition on February 27, 2017, MBS paid us $7,376 and $5,009 related to these commissions in Fiscal 2017 and Fiscal 2016, respectively. In addition, the Supply Agreement contains restrictive covenants that limited our ability to become a used textbook wholesaler and that place certain limitations on MBS’s business activities. We also previously entered into an agreement with MBS pursuant to which MBS purchased books from us, which have no resale value for a flat rate per box. Prior to the acquisition on February 27, 2017, total sales to MBS under this program were $339 and $574, for Fiscal 2017 and Fiscal 2016, respectively.

MBS leases its main warehouse and distribution facility located in Columbia, Missouri from MBS Realty Partners L.P. which is majority-owned by Leonard Riggio, with the remaining ownership by other sellers of MBS. The lease was originally entered into in 1991 and included a renewal option which extended the lease through September 1, 2023. Based upon a valuation performed as of the acquisition date, the lease was determined to be favorable from a lessee perspective with below market rent.
