I just ordered a few Elevator Books from Elevatorworld.com. They aren't cheap, but I believe that It might help to familiarize myself with the nomenclator of the different parts, materials, tools, and the general process of installation. I wanted to know if anyone wants to split the cost of one of the ebooks "PDF" titled: "Elevator 101 3rd Edition." When I purchase this book, I will receive 4 extra copies for download. Let me know if you are interested. Here is a link to the book I'm referring to, http://www.elevatorbooks.com/Products/1013RDPDF/Elevator-101-3rd-Edition-Digital-Edition.aspx
