The Doucette Library organizes materials on the shelf using the Dewey Decimal system You'll find things more quickly by understanding how call numbers are organized on the shelves.
What about narrowing your search to a particular type or format of material - perhaps to picture books, or video formats, or kit material? See all the formats we have on the collections page, with advice on how to search for those you want. You might discover formats you never knew we had.
If your challenge is more in finding appropriate journal articles, then you might find our workshop handout about Tips for Searching the ERIC database helpful.
And - last but not least - ask for help at the reference desk. That's what we're here for!
