We're supposed to be civil here but frankly the linked post is twaddle. You can't give the reason for not having unaffordable personal libraries and then disregard it immediately because you're selling your theses, whatever those might be. The thing is books used to be very expensive, yet people managed to read as many as they could get their hands on and even spend crazy money on them. Open any book from say the 17th century and you'll see how they quote as many works as they could. Take the Quixote for instance, there's a famous chapter about the library of Don Quixote, the whole novel is built around satirizing a popular genre that Cervantes as an avid reader also knew well.
