This set of databases has some really useful sites. For those with English assignments, the Literature database is very helpful. If you are looking for newspapers, in English and in Spanish, there are a couple of databases for you. The coolest site is actually the Testing & Education Reference Center, which is a huge database of testing preparation materials (TAKS, SAT, ACT, GED, ASVAB, etc.), college searches, scholarship searches, and career materials. This database is so large that it is recommended that you get your librarian to give you a quick tutorial (5 minutes or so) to help you find the cool features.
Ask your teacher or librarian for the username and password for this site.
