An article of manufacture, comprising:

• a computer storage device;
• and
• computer program instructions stored on the computer storage device, that when executed by a computer, comprising a processing unit and storage, configure the computer to:
• implement a content management system storing items of content, each item of content comprising data indicating whether the item of content is published in electronic documents available from a second source of electronic documents;
• send a request to retrieve a published electronic document from a first source of published electronic documents, the request comprising a resource identifier for the published electronic document;
• receive the published electronic document over a computer network from the first source of published electronic documents;
• based on structure and content of the published electronic document, extract information from the published electronic document;
• generate queries, based on the information extracted, to query the content management system;
• process the results of the queries to identify content available in the content management system corresponding to the queries and relevant to the published electronic document, and to identify whether the content available in the content management system is published in the electronic documents available from the second source of electronic documents;
• and
• communicate information indicative of the content available in the content management system and relevant to the published electronic document and not yet published in the electronic documents available from the second source of electronic documents.

A computer-implemented process performed by a computer system comprising a processing unit and storage including computer program instructions that configure the computer system to perform the computer-implemented process, the computer-implemented process comprising:

• sending a request to retrieve a published electronic document from a first source of published electronic documents, the request comprising a resource identifier for the published electronic document;
• receiving the published electronic document over a computer network from the first source of published electronic documents;
• based on structure and content of the published electronic document, extracting information from the published electronic document;
• generating queries, based on the information extracted, to query a content management system, wherein the content management system stores content and is accessible for queries on the content, and wherein an item of stored content has data indicating whether the item is published in electronic documents available from a second source;
• receiving, from the content management system, results of the queries;
• processing the results of the queries to identify content available in the content management system corresponding to the queries and relevant to the published electronic document, and to identify whether the content available in the content management system is published in the electronic documents available from the second source;
• and
• communicating information indicative of the content available in the content management system and relevant to the published electronic document and not yet published in the electronic documents available from the second source of electronic documents.
