Hiking routes found in books
On the [Dutch forum](http://forum.openstreetmap.org/viewtopic.php?id=32678) we have a discussion about mapping of hiking routes that can only be followed using a book or leaflet. They are not signposted on the ground. Most likely, the book has the typical copyright "nothing can be reproduces without ...". So far the mapper has not shown that this is not the case.
It is my belief that we should not map them or that we even are not allowed to map them.
So my questions are:
- Can we map them ?
- If not, is there a webpage that states this that I can refer to in the discussion ?
thanks in advance
