The BBC reports on the British Library's latest venture into e-books.
For a monthly subscription fee, users can access digital copies of more than 40,000 classic books available for the iPad.
Texts appear in fully digitised form, complete with original page markings and drawings, as opposed to the plain formatting associated with other types of e-books.
All of the works date from the 18th and 19th centuries and include novels, poetry and historical accounts.
