title: Change Document Class in LaTeX
body: <p>I am writing my thesis in LaTeX with lilypond and lilypond-book. The first part of the document is just musical examples and for that, the document class {book} suffices. The second part, however, needs to follow the conventions of stage.cls . I was wondering if it is possible to change document classes at that section. I have tried to include the PDF file of the part of the document that uses stage but it ruins the table of contents at the front of my thesis, and it also restarts page numbering.</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>Thanks</p>
