An apparatus receives a first selection command to select a part of an area of a displayed first document (e.g., text, image, etc) as a selected area. When the apparatus receives the first selection command, the apparatus causes display content included in the selected area selected in response to the first selection command to be stored in a storage unit and determines whether link information linked to second document is included in the selected area. The apparatus acquires document data of the second document using the link information in response to determining that the link information is included in the selected area.
