At UCLA, library staff places high value on “search as service” and also on information literacy. Google Scholar™, as other scholarly search engines, allows and enables users to search over scholarly content. Our decision to “elevate” Google Scholar™ to our home page reflects and supports these values. Our decision to nest Google Scholar™ within the context of the research process writ large similarly reflects these values, serving, at the same time, to reinforce the Library’s relevance to the academic success of our users.
