A system to assist a seller in creating product catalogues using a database and a separate pagination program. Information regarding specific, desired products is collected from the database. It is modified by Markup Interchange Format ("MIF") code wherein directives are added that determine what information will be included in the final catalogue. The MIF code file is formatted so that it is compatible with the pagination program, and the resulting file is flowed directly to the pagination program. This method and computer program reduces the likelihood of errors, redundant work, and costs for automated processing of catalogues. The resulting file provides data and the specifications useful for creating a formatted, printable or viewable output.
