Hello,
Generally speaking, we do not have a collection of audio books here at MHC. We may have a few that we've acquired over time for specific purposes. If you'd like to search for them, you can go to the LITS homepage, then click on the "Catalog" tab, then click "Advanced Search". On that page, select "Spoken Word" from the drop-down menu for format. If you want to limit to MHC, you can select MHC in the location drop-down menu.
I would recommend visiting a public library for audiobooks! Audible.com also offers a free trial.
Let us know if you have other questions!
Best,
Julie
