A system and method for identifying and/or annotating location for a desired event. This location annotation system and method presumes the existence of two components. The first is a location history (a record of a person, object, or other entity's location history, with locations of the person, object or entity time-stamped so that the record contains location information for a particular time or times). The second component is a set of one or more documents which are time-stamped. The time-stamp is typically meaningfully related to a critical event in the lifetime of the document (e.g., creation time, modification time, and so forth). A document can be any electronic entity, regardless of its permanence or the means by which it is stored. Given the two discussed components, the location annotation system and method consists of a variety of methods for processing the time stamps of the document(s) to be annotated with the location history such that documents can be associated with the location at which critical events, or other events of interest, in the document lifetime took place.
