Can't wait to see the catalogue details! pdf995 is a good piece of software which costs nothing to download and use and converts text and images to pdf very well.
In passing there are also some good photographs of Moel Fferna and others in the Oakewood Press book "The Industrial Tramways of the Vale of Llangollen" by J.R.Thomas & D.W. Southern. Surface of course, being a "railway" book, but very interesting, never the less. (Usual disclaimer - nothing to do with me at all!)
Keep it coming!
