The British library has what could only be described as an extensive library and catalog of books, but are you aware of just how many and the length of time it would take you to read each one?
Well, if you were somehow able to read five books per day, it would still take you over 80,000 years to complete everything, and that is only with them no longer bringing in any additional books to add to the catalog. It just makes you think about the space that they have in order to store them all and anyway who would be able to read five books per day every single day anyway?
