One thing that always surprises me is that the Mid Hudson library system has no books on Geographical Information Systems. 📚 

Seems so odd with GIS being such a big topic these days and powerful GIS software like QGIS widely available – with mapping, GPS and aerial photography such a big part of our lives today. YouTube, free web classes and internet documentation is great but it sure would be nice if they had books that one could read about at the library.
