Additional documents are automatically located that are relevant to an original document, such as a document being read by a user, and also potentially relevant to personal information of the user. The additional documents may be located based on descriptive information that includes personal information of the user and content information of the document being read. The additional documents, or links to the additional documents, may be incorporated into the document being read. In some implementations, the additional documents may be presented in-line with the document being read, such as through an in-link link or text snippet. The user can thus be efficiently presented with additional information that is relevant to the original document being read.
