Libraries are a valuable resource and there's no better time to rediscover the treasures available at your local branch than during National Library Week, which runs April 14-20 this year. More and more eBooks are being offered for free through libraries. In fact Penguin just announced a plan to ease restrictions on their eBook titles, now making them available for free through library lending. Getting your hands on free eBooks is easy as long as you've got a library card.
