Calisphere is the University of California's free public gateway to a world of primary sources. More than 150,000 digitized items — including photographs, documents, newspaper pages, political cartoons, works of art, diaries, transcribed oral histories, advertising, and other unique cultural artifacts — reveal the diverse history and culture of California and its role in national and world history. Calisphere's content has been selected from the libraries and museums of the UC campuses, and from a variety of cultural heritage organizations across California.
Calisphere is a public service project of the California Digital Library (CDL). Through the use of technology and innovation, the CDL supports the assembly and creative use of scholarship for the UC libraries and the communities they serve.
Ask KidsAsk Kids
is a search engine designed exclusively for young people ages 6 to 12. It's a free, safe, fun way for kids and their parents to quickly and easily research school topics like science, math, geography, language arts, and history in a search environment that's safer and more age-appropriate than traditional, adult search engines. Each web site in the Ask Kids core search index was selected by the Ask.com editorial team as child-appropriate or as a relevant and practical site for reference and learning. Ask's proprietary search algorithm then identified communities and collections of web sites linked to the core list, and filtered those to remove adult content.
