This is the back of the bookshelf
All of the libraries I have posted so far have been in chateaus and other equally inaccessible (for most people) places. However today I am sharing a wonderful library I found on The Steampunk Home blog. It's a contemporary secret library that's relatively doable.The first picture is an unassuming bookshelf, then it opens and the rest of the images are of the inside. Please read the full article here.
Here is a more modern style take on this fun concept. Not sure if the room behind the shelf door is a library, people with minimalist style are more inclined to have a digital/electronic/virtual library but it's good that secret rooms are not entirely a thing of the past or people who cling to the past.
