Where I do find the GED prep program you used to have under the Database site? It seems it's no longer listed there.
The database you are looking for is called Learning Express. It can be accessed by going to the library home page.
On the right side of the screen is a tan box titled "Library Resources". The first link under the heading is Databases. Click it to got our database page. All databases will be arranged alphabetically. Scroll down to Learning Express and select the link to log in.
