The Library has recently added 44000 eBook records to the Library catalogue, including a fair swag of law-related material. It's a package deal.
You can discover what's there as part of your usual catalogue searching.
Or you can search specifically within the eBook Library - start from the Library's homepage, go to the Article Databases link, browse the letter E and select EBL Ebook Library. Or click this link to take you most of the way. Money changes hands so you'll need to do the username-password thing. Once you're there, the search interface is pretty intuitive. You can browse by category (e.g. Law), or use the Advanced Search. You may need to consult the online manual as well. Let us know what you think of it.
