"Read full-text of an article for up to 24 hours for as little as $0.99. Rented articles can only be viewed at DeepDyve and cannot be downloaded, printed or shared. Basic DeepDyve accounts, which can be set up at no cost, come with 3 free rentals to allow readers to preview the functionality and presentation of rented articles."Depending on the article, this could be useful, although I don't see that I would personally use it much. I can live without the printing/saving option most likely, but the 24 hour access would be the real challenge for me. There are very few articles that I look at just once. Even if I am using an article for a current project (as opposed to something that is of general value), I usually can't pull all the relevant details with just one look - I keep going back to articles as my knowledge advances.
