1) Make sure you've selected the Milner Catalog tab on Milner's homepage. You can enter keywords into the basic search box, but you get a lot more flexibility using the Advanced Search link just below that box.
2) On the Advanced Search page, enter your keywords into the available search boxes.
3) On the right side of the results page are a number of ways to specify your search. For example, if you only wanted to find e-books, you could select the available online in the availability tab. You can also specify that you're looking just for Books under Resource Type. This prevents other kinds of items, like videos to pop up in the results.
Watch the video below to see how to find and request books through Illinois's I-share network.
To search for books outside of Milner or I-share, use the WorldCat catalog. This is a larger interlibrary loan system for books, much like interlibrary loan for articles.
