The Peninsula Library System Catalog includes books from libraries throughout San Mateo County.
To access and search the catalog you will need go to the library's homepage and select the Books tab. Once selected, type in the keyword (e.g. your topic) that you are researching then select the Go button.
Reference works are a good place to begin your research, as they generally provide background information and often cite longer, more authoritative research works on the topic.
Tip: keep an eye out for important words and phrases to try in your keyword searches.
