The database ACLS Humanities E-Book now has 1700 titles online.

In September 2007 HEB released its next round of 170 e-books. In addition to titles in history, these include e-books in new fields incorporated over the last two years in Australasian, Byzantine-Mediterranean, Canadian, Caribbean, Oceanian, and women’s studies and in Native Peoples of the Americas. Over the course of the coming years HEB will add 500 more titles annually in archaeology, architecture, art history, folklore, literature, musicology, political science, religion, and the histories of science, law and philosophy.
The database is produced by The American Council of Learned Societies.
