The format in which the full texts are offered is PDF/A (PDF, archive-safe).

  With the help of the browse button you can search on your local computer 
  for the files that you want to submit.

  Currently the following formats are supported:
  PDF (Portable Document Format), ZIP (compressed file), Video (MP4), Cover (png)

  If you bring in several sub-documents (for example, attachments), 
  please pay attention on a meaningful naming of the individual files 
  (for example: kap01.pdf, kap02.pdf etc.), as these will later be displayed 
  to the user in alphabetical order.
