While building a home library the three basic elements required are: space, shelves and books. You can either custom build a new room or choose an existing spacious room to house your books.
Recessed or built-in bookshelves can provide floor-to-ceiling storage and space savings. You can also mount hanging bookshelves onto the wall or buy glass cases, which might be preferable if your collection includes antique books that you want to preserve. As your bookshelves creep up the wall, you may need a library ladder to reach them
When considering library furniture, you may want desks if you are writing and taking notes on your reading. Bookstands are also helpful for reading those big volumes that are too heavy to hold up comfortably. You can include overstuffed couches and chairs which will beckon guests to spend a few hours reading.
Finally, a good system of organization will help you find the book you want quickly. You can also decorate bookshelves with personal items, such as photographs and souvenirs which can break up the rows of books visually, and it would also give you room to expand as your collection grows.
