There are basically four types of stamp album pages — commercial pages in a variety of styles and sizes with pre-printed spaces, blank commercial pages, the print-your-own variety available online, and those you make yourself either via software (dedicated or adapted) or by hand.
Most of us started out collecting by filling spaces in a commercial pre-printed album. A beginning stamp collector’s goal is usually to “collect the world,” attempting to fill all of the spaces in such an album. But with time the challenge of filling the album eventually becomes too daunting and the collector begins to look elsewhere for inspiration. Often, they then start to “specialize,” perhaps purchasing a pre-printed country album with the stamps of their own country often being the focus.
