An absolute scam, stay away. You're much better off using your local library, which is free and has infinitely better resources as well as personal assistance.
Tip for consumers: You're going to be required to sign up for a subscription that automatically renews AND the site makes you jump through a multitude of hoops to cancel. And the subscription doesn't give you unlimited access! It just gives you a number of credits which you then have to pay out for each signature you look at. When the credits are gone you either have to buy more or wait until the next month's "subscription."
