Ok, so I stretched the truth. I have no pics, and outside the data files have never seen a precursor library. I've seen the logo in files, I've seen the .xml somewhere, but never the thing.
If you have ever had a library, please post a pic or (prefferably) a savegame if you have one. I REALLY want to see, because people claiming to have ever had one a few and far between. So, a massive call to arms (well, fingers) for the screenshots!
