Needing to find any book that you cannot find in digital format? The Harvard's Public Bookstore is a place where maybe you can get books that are really hard to find in the Internet, such as technology, history, maths, physics, crypto or fairy tails stuff. I was looking for "The Truth About Crypto" for a long time from now and I have been finally able to buy it. I needed to go through a lot of places before met it, I was in MIT's and Boston Public Library before, but it was matter of time. This books will help me to create more and tangible courses about these technologies for individuals and businesses that want to learn about those subjetcs. Besides it, I was very hesitated to almost get those three including the trending AI and X-MEN ones but I resisted. I spent $22 dollars that day but it's worthy so far due the book is pretty well, I can't wait to share my thoughs and teachings with y'all already. And you, do you like books too?
