Powell's City of Books in Portland is one of the largest bookstores in the world, filling an entire city block. It holds about one million books on shelves spread across many colorful rooms.
It is famous because it sells both new and used books side by side, so you can find almost any book you can imagine. Book lovers travel from around the world just to explore its maze of rooms.
The store is so big that the rooms are named by color to help you find your way. Visitors get a free map to explore all the shelves.
On the same shelf you might find a brand-new book right next to one that is a hundred years old. This makes every visit a fun treasure hunt.
There is a big, bright childrens section called the Rose Room full of picture books and stories. Kids can sit and read while grown-ups browse nearby.
