The archived version of a party web site may differ slightly from the site as it appeared on the download (archiving) date. When archiving takes place, certain technical modifications are required:

• For the purpose of presentation in the archive, internal links in the web sites have been modified.
  
• In the case of external links, the intermediate page is generated with a note, which reads as follows in Dutch (English translation in brackets):
  'De pagina waarnaar hier wordt gelinkt bevindt zich buiten de gearchiveerde site. Mogelijk bestaat deze pagina niet meer, of bevat hij niet (meer) dezelfde informatie als op de datum van downloaden.' (The page to which this link relates is outside the archived site. It is possible that the page no longer exists, or no longer contains the information it contained when it was downloaded for archiving).
  
• Each publicly accessible page of the site is archived, with the exception of pages that are excluded by the webmaster using the file robots.txt.
  
• Certain interactive sections of sites have not been archived (e.g. search engines and chat boxes).
  
• Extensions other than '.htm' and '.html' (e.g. '.asp') have been converted to '.html'.
  
• All files which were already in the archive and have not changed since the last download are linked by so-called soft links from their new location to the previous existing file. This means that only one copy of a file is stored in the archive.
  
• Each year, all party sites are integrally downloaded, i.e. without modifications and without external links. This means that a single, authentic version of the web site is available each year.
