ECCO provides access to the digital images of every page of many books published during the 18th Century. With full-text searching, it gives researchers access to critical information in the fields of history, literature, religion, law, fine arts, and science.
ECCO includes books and directories, Bibles, sheet music and sermons, advertisements, and works by many well-known and lesser-known authors. There are works by women writers, collections on the French Revolution, and numerous editions of the works of Shakespeare.
Multiple editions of each individual work are offered to enable scholars to make textual comparisons of the works. The majority of works in ECCO are in the English language but there are also works printed in Dutch, French, German, Italian, Latin, Spanish and Welsh.
