I created a number of route pages, most of which are pretty bare bones. I have been making an effort to improve them. I have climbed all of the routes that I have created pages for. When I create route pages I write from memory. Some of these routes I climbed years ago and don't remember pitch by pitch beta. I could easily look up the beta in a guidebook, but I haven't because that feels like plagiarism. Some of the routes are otherwise undocumented so there is no other source of beta for the route.
So, my question. Is it acceptible to use the information in a guidebook to augment my memory? This would no doubt improve the route page, but doesn't sit right with me. Also, is it acceptible to use other member's photos in the route pages?
