British Library Direct is a new (well, newish!) service offered by the British Library. It's a secure electronic delivery service for journal articles, and contains the past five years worth of articles from 20,000 of the British Library's most popular research titles.
You can order a copy of any article you find on the database, pay by credit or debit card, and choose an electronic delivery time from two hours to five days. It's all pretty convienient - the only catch is that you need to have a full (but free to download) version of Adobe Reader, with digital rights management activated.
Here's just some of the titles held at the Caird Library that are available via BL Direct:
International Journal of Maritime History
Nautical Archaeology
Ships Monthly
Shipping and Trade Law
Shipping World and Shipbuilder
Warship
