You can use the IUP Libraries' online catalog to search for books on a certain topic and limit your search to books in certain languages.
You can access the library catalog from the IUP Libraries website at www.iup.edu/library. In the Search Our Collections box, enter a few words that describe what you're looking for. In the "Search In" drop-down menu, choose Library Catalog. Click Search.
On the right side of the screen, you see a list of limits. Scroll in the list until you see the Language limit and click on the language you are interested in.
Your search results list will now only show books, both hard copy and online, that are written in the language you selected.
