The British library has started transfer in to a digital format more than hundred thousand ancient books that were inaccessible to the general public before. Basically it is a question of XIX century books which were not republished any more, and their authors have frequently appeared to be forgotten. It is planned to scan daily about 50 thousand pages, scanning of first 25 million pages will take about two years, and for transfer of all collection in a digital format 30 terabyte will be required.
