1. A method for finding documents which are accessed through the Internet and relate to a portion of a temporal document, comprising:
- (a) in response to a signal of interest at a particular time during the temporal document, identifying a portion of the temporal document for which related documents are to be found;
(b) selecting the related documents by use of information retrieval techniques from among a collection of documents which may be accessed through the Internet, by utilizing databases comprising information about the collection, according to the scores achieved when evaluating documents in the collection according to a formula giving scores to documents depending upon the occurrence in the documents of terms which occur in text associated with the portion of the temporal document identified, wherein a score SD of a document D in the collection may be determined by crediting the document D, for each term T in the temporal portion of the document identified which occurs in the document D, with an amount proportional to Robertson'"'"'s term frequency TFTD and to IDFT where
