You can wrap middleware in a function to black or whitelist certain urls. This is a whitelist example:

function allow(paths, fn) {
  return function(req, res, next) {
    if (~paths.indexOf(req.url)) {
      return fn(req, res, next);
    }
    next();
  }
}

You wrap it around your middleware like:

app.use(allow(['/bibliotek', '/registrer'], express.cookieParser()));

You can use the same technique for other middleware as well. This was based on a gist that the express author showed in irc.
