Some embodiments provide a method for storing a document. The document is created by using a set of template pages. The method, in a data storage structure, creates a first prototype section for storing information for the template pages. The method also, in the data storage structure, creates a second section for storing a set of content for the document. In some embodiments, the template pages are provided by a word-processing application. In some embodiments, the information for the template pages includes text information, image information, and thumbnail information. In some embodiments, a word-processing application utilizes the stored thumbnails in the prototypes section to generate a visual representation of a template page contents to a user to assist the user in creating a document. In some embodiments, the template pages further include stylesheet information, headers information, and footers information.
