Cambridge University Press has published more than 41,000 ebooks on Cambridge Core. Almost all recently published titles, as well as many older titles are available on Cambridge Core. This said, our back library is extensive and it has not been possible to digitise all of our titles yet. Cambridge Core is the principal academic platform from Cambridge University Press. It replaces and combines content from Cambridge Journals Online, Cambridge Books Online, Cambridge Histories Online, Cambridge Companions Online, and Shakespeare Survey Online.
