Conversion data representing a document to other formats for manipulation and display

1. Field of the Invention A computer implemented method of converting a document in an input format to a document in a different output format is disclosed. The method generally comprises locating data in the input document, grouping data into one or more intermediate format blocks in an intermediate format document, and converting the intermediate format document to the output format document using the intermediate format blocks. Each intermediate format block may be a paragraph, a line, a word, a table, or an image. The input document may be received over a network and the output document is sent over the network. A linked table of contents and/or an index may be generated. A computer executable program may be generated and inserted into the output document for selecting one output format for display. The output document may be displayed by locating sub-page breaks in the document, subdividing the document into sub-pages using the sub-page breaks, locating blocks within each sub-page, and sequentially displaying all or a portion of each block of the sub-pages within display parameters of a display configuration. Tables may be divided to be displayed in more than one display page. The converter may be incorporated in a computer program product for maintaining a repository of input documents in one or more storage formats.
