Albums are made with a spacer which creates a double thickness at the spine, so that there is space to attach things to the pages. This means that the book won't bulge when it is full. You can use both sides of the pages, and also draw and write on them. (They don't have transparent leaves between the pages.) They are suitable for all kinds of paper memorabilia such as letters, tickets, photos, invitations, recipes, certificates and scrapbooking in general.
