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.
Many public libraries offer entry-level online language-learning tools like Mango Languages or Rocket Languages to residents with appropriate library cards. (Tech students qualify for cards at the Blacksburg library and other branches of the Montgomery-Floyd Regional Library District [MFRL] no matter where their homes are.)
Check with your local and/or hometown public library about your options.
Tech's University Libraries seek user input about possible purchases of online resources; October, February, and April are the primary trial months. Let us know how (if...) a trial fits the research, teaching/learning, and public service missions of the university. Share your judgments through the short survey linked to each trial blurb and/or more detailed remarks in an email to a subject librarians.
All active trials are listed in a sidebar on the Databases A-Z guide, usually including their expiration dates and links to online user evaluation surveys. Here I list current trials of likely interest to the departments I serve.
