Is your collection of books ever-increasing, and the storage space is on the verge of decline? Then Extended Cab is a great bookshelf for your small library. Designed by Dutch designers at Sloom & Slordig, the bookshelf lets you lift up your library as much as you want. The shelves make use of four to seven frames that are combined to accommodate your book. Add the piles vertically or horizontally, and make more space in small, limited space. Let your interest for some more good books grow, as your bookshelves can still accommodate them.
