Search the KUA Library Catalog by keyword and sort your results. When you find relevant books, follow the subject headings. To refine results, add more keywords to your search (such as "italy" or "europe*"). You can also use the "not" function to eliminate terms (for example, NOT "harlem" to remove any books about the Harlem Renaissance).
Suggested search terms: evolution, creationism, intelligent design, reformation, science education
These are great sources that are freely available on the web.
