CrossRef Search is a vertical search engine that indexes food, health, sport and digital commodities. Instead of returning thousands of links from a query CrossRef Search delivers value, quality and quantity. Make sense of the health informmation you just found and use CrossRef Search as an interface to organise it. With the rise of the internet, sharing data has become a simple matter. CrossRef Search welcomes your feedback and encourage everyone in the world to share and link to the articles. The supply and demand model, a learning experience!
