Some stamp albums feature specific categories with pictures of the stamps that should appear on each page. You may want to select one with loose-leaf pages so you can add pages as your collection grows. A stock book is an album with plastic or paper pockets on each page. There are no pictures of stamps, so you can organize the album your way.

I have the Victorian Love Album. It has 2 posts on the side that come unscrewed so you can take the whole book apart to add more pages. Very handy for large collections, because the book is expandable.
