I found this in English but it is German. It concerns the geology of building materials in Paderborn, Germany. The print on my monitor is great, but by lower back hurts if I sit too long at my computer. I printed the 21 pages of the pdf and will continue reading it from the comfort of my bed. It will be like trying to digest a cow. But what I've read so far is very interesting - to me. I plan to post several excerpts in the future.
