To enable intuitive operations on document data.

The document management program is implemented in an information processing apparatus comprising: an image display unit 303 that generates display information on a document list unit for displaying document data in list form; an operation receiving unit 302 that receives an operation of dragging and dropping first document information displayed on the document list unit onto second document information; and an image processing unit 304 that, in response to the received operation, adds a document included in the first document information to a document included in the second information, stores the added document as one piece of document information in an association manner, and subsequently deletes the first document information.
