Here is a collection worth 5 year 10 months of mine, with 50+ GB of E-books of more than 80 branches of geology, software like Matlab, R, Petrel, ArcGIS, ENVI, Erdas Imagine, Office 2016, Surfer, Rockworks etc. Almost all of them are backdated, but they work fine for our academic purpose so hope it will come in handy. And finally I uploaded a documentary from History, "How the Earth was Made" which explains the earth's majestic elements from a geologists point-of-view. Nonetheless if you are an Earth enthusiast you can always give it a try! It is really good!!
