Yeah. I realized the moment I pressed "post reply". Sorry.
No. I have no permission whatsoever. I just looked the page through for any explicit limitation of diffusion of the contents and found none. I didn't find any contact info either so I cannot even ask. That is why I added the source link, so you could check and decide whether it is ok or not.
If it is not, then maybe we should create a parallel index with links to books displayed in this way, so everybody has access and can edit these books on their own. Maybe this book cannot be posted, but the link sure can.
