A digital processing device is configured to perform a method comprising: identifying logical page numbers of a document, the identifying constrained to identify either zero or one logical page number per page of the document, the logical page numbers and an ordering of the pages of the document defining an ordered sequence of logical page numbers; identifying a sequence of logical page number references in the document, each logical page number reference matching one of the logical page numbers of the document; and selecting a sub-sequence of the sequence of logical page number references for which corresponding logical page numbers are in a nondecreasing order in the ordered sequence of logical page numbers. The sub-sequence is used in organizing the document, for example by generating hyperlinks linking the logical page number references of the selected sub-sequence with corresponding pages indicated by the logical page numbers.
