Explore the print Reference collection on the 1st floor of the Library. Most reference books check out for 24 hours. Also, many reference materials are also in the general collection and/or available as e-books. They are all included in the Library's Online Catalog - Fusion and/or FusionPlus.
The ISU Library acquires e-reference books from a variety of publishers. Some e-books are 'one user' at a time and some are multiple user. Copy/paste a title below into either the Electronic Resources portal search box (gold) or the online catalog (fusion.indstate.edu). We get new e-book titles all the time; these are just some, so don't forget to search for more - if you search the online catalog for your topic you'll retrieve both print and e-book results.
