Our OverDrive collection of eBooks has a number of test preparation guides. To locate them, go to the OverDrive page, click on the Connect to OverDrive button, and use the Search box at upper right. Enter GRE, LSAT, or TOEFL to find preparation books for those tests.
The Education and Careers collection maintains also a few print subscriptions to test preparation guides. We recommend purchasing the latest print edition of any test prep guides so you can mark up the guide and take the sample tests at your convenience.
