Google Books adding British Library titles

Here is an interesting news article from CNET about Google Books agreeing to scan and add to their collection 250,000 books from the British Library.  The items, including books, pamphlets and journals, are from the years 1700-1870, and will undoubtedly be of much interest to those studying the 18th and 19th centuries.  The press release from the British Library has more details on the agreement, along with some examples of the titles that will be included.
