From the press release:
Digitised photographs, maps, paintings, museum objects and other images make up 64% of the Europeana collection. 34% of the collection is dedicated to digitised texts, including more than 1.2 million complete books that can be viewed online and/or downloaded. The texts cover thousands of rare manuscripts and the earliest printed books (incunabula) from before 1500. Video and sound material represents less than 2% of the collections. Much of the material accessible through Europeana is older, i.e. out of copyright, items, due mainly to the difficulties and cost of rights clearance to digitise and give access to in-copyright material (even for material that is no longer commercially distributed or out-of-print) or material whose potential right-holders are unknown (orphan works).
