If you want to learn on the go or don't want to depend on internet access, the Virginia Tech Libraries have a large collection of language learning compact disks on the 5th floor of Newman Library that you can check out. These links will show you their call numbers and check-out status.

Check with your local and/or hometown public library about your options.
