2026–27 edition

Chicago

The original directory. Certified vendors in front of purchasers across the Chicago Public Schools network.

CPS Vendor Source Book

The CPS Vendor Source Book has been published since 2011 as an independent B2B directory for vendors serving Chicago Public Schools. It is a 24-hour discovery hub — print heritage, digital reach — where purchasers search approved suppliers and vendors get seen when it counts. The current 2026–27 edition continues that work under the EdMarkt umbrella.

Published independently since 2011. 2026–27 edition.
