A scalable computing system for managing annotations is capable of handling requests for annotations to millions of documents a day. The computing system consists of multiple tiers of servers. A tier I server indicates whether there are annotations associated with a content source. A tier II server indexes the annotations. A tier III server stores the body of the annotation.
