I was going through Pinterest and came across this picture of the Trinity Library in Dublin, Ireland. I remember when I was there no photography was allowed....well, it was pretty dark in there anyway. What a place! Along the middle were display cases holding old tomes that were ancient or some having had an important place in history. What a library, Wow, try finding your favorite book on these shelves.
In another room was the Book of Kells, an ancient manuscript completed around 800 AD. For more info on the Book of Kells go to the link below. https://www.tcd.ie/Library/manuscripts/book-of-kells.php
