CliffsNotes are a series of student study guides. The guides present and create literary and other works in pamphlet form or online. Detractors of the study guides claim they let students bypass reading the assigned literature. The company claims to promote the reading of the original work and does not view the study guides as a substitute for that reading.[1]
CliffsNotes was started by Nebraska native Clifton Hillegass in 1958.[2] He was working at Nebraska Book Company of Lincoln, Nebraska, when he met Jack Cole, the co-owner of Coles, a Toronto book business. Coles published a series of Canadian study guides called Coles Notes, and sold Hillegass the U.S. rights to the guides.
Hillegass and his wife, Catherine, started the business in their basement at 511 Eastridge Drive in Lincoln, with sixteen William Shakespeare titles. By 1964, sales reached one million Notes annually. CliffsNotes now exist for hundreds of works. The term "Cliff's Notes" has become a proprietary eponym for similar products.
IDG Books purchased CliffsNotes in 1998 for $14.2 million. John Wiley & Sons acquired IDG Books (renamed Hungry Minds) in 2001. In 2011, CliffsNotes announced a joint venture with Mark Burnett, a TV producer, to create a series of 60-second video study guides of literary works.[3] In 2012, CliffsNotes was acquired by Houghton Mifflin Harcourt.[1] In 2021, CliffsNotes was acquired by Course Hero.[4]
