29 journal publishers are opening their scholarly content for the first time to free, full-text searching between publishers through the pilot project CrossRef Search.
Through a reciprocal arrangement between Google and CrossRef, the Pilot launches a typical Google search but filters the result set to the scholarly content from participating publishers. Google has indexed the full text of scholarly journal articles on the publishers' websites through a CrossRef gateway. Users may submit searches from CrossRef Search Pilot boxes on participating publishers' sites. Results are returned from Google using the Google search and ranking algorithms, and using the article's DOI whenever possible to link from the search results to the published article.
