Headers and footers can include a date, automatic page numbering, bates numbers for legal documents, or the title and author. Each new position is like the new card handed to you by the dealer, and you need to insert it into the correct place in the sorted subarray to the left of that position. Creating a master document when working with large word files. It is much less efficient on large lists than more.
