Unless you are very familiar with your country or region it is a good idea to get background information first. Books often provide this so a search in Oskicat for general works is usually worth it. You can then proceed to find more detailed information in journal articles. Rather than looking on the web for a project, see if you can find a related article first. Then if you wish you can search for primary sources for descriptions and outcomes of the project.
Why use Google Books? Library catalogs (like OskiCat) don't search inside books; using a library catalog, you can search only information about the book (title, author, Library of Congress subject headings, etc.). Google Books will let you search inside books, which can be very useful for hard-to-find information. You can then use Google Books' Find in a Library link to locate the book in a UC Berkeley library, or search OskiCat to see if UC Berkeley owns the book. Try it now:
Since the UC Berkeley Libraries have a world-class collection used by scholars who speak and read many languages, you may see many non-English titles in your search results. If you prefer to see only English-language materials, you can limit your search results in OskiCat or Melvyl by language.
In OskiCat: After you search, click on either the Modify Search or Sort/Limit Results buttons near the top of the page. Under Languages, select English on the pull-down menu, then click the Submit button. (You can also select more than one language by holding down the Ctrl key on a PC, or the Command key on a Mac.)
In Melvyl: After you search, look for the "refine your search" sidebar () on the left side of your search results page. Scroll down to see an option to limit your results by language.
