The British Library has today unveiled its upgraded electronic delivery service, which will allow it to send digital copies of almost all the items in its collection direct to a researcher's PC within two hours.

The service, which launches this autumn, builds on the library's existing secure electronic delivery service, which began in December 02 by providing 'born digital' documents. It has now added a professional scanning service, which means it can send out both printed and microform documents digitally.

This addition to the digital delivery service, means that researchers can now get access to over one billion items via their desktop. "This breakthrough will allow customers to deal direct with one of the world's great knowledge holders," says the British Library's director of operations and services, Natalie Ceeney.
