Each of these playlists is made up of multiple videos, and each of those is about 2 minutes long, give or take.

Sunday: 4PM to Midnight

Friday: 7:30 a.m. to 4:30 p.m.
Saturday: Closed
When off-campus, if you are a Lyon College student, faculty, or staff member, you can use your Lyon user ID (first.last@lyon.edu) and your password to login when an authentication screen pops up during your use of a library database or other online service. You only have to do this once a session.
Community members who have purchased a card can use the databases in the library building but not remotely.
Having issues logging in? Clear your cache (CTRL + SHIFT + DEL) and try again.
If you have problems accessing the databases please call Lyon support at: 870-307-7555 or contact support@lyon.edu.
For those of you who want to get the most out of your calculators, here are some professional development webinars. Each is about an hour long.
