Three ringed and post bound photo albums allow for page addition. Your family photo album will expend as your family memories accumulate.
Book-like binding are attractive, photo albums with sheet protectors are attractive and durable. On the right you can see the photos of the exposed posts that bind and keep the pages of this album together and a side view of the pages held together.
All photo album materials, pages, layouts and embellishments should be archival (both acid and lignin free) to keep photos from fading or yellowing with time.
Archival (non PVC) sheet protectors are recommended, to protect photographs from environmental damage and oils from human skin. When adhering photos to the layout, make sure to use only acid free (archival) adhesive to keep photos from discoloring and deteriorating with time.
In summery, choose a cover that works with your theme, choose album size that will work best with your subject and desired photo sizes. Use materials that are archival safe (acid and lignin free) to keep your photos from discoloring and use sheet protectors so viewers can point at their favorite photo without leaving their fingerprint on it. If your theme or subject is a growing/developing one (school years, baby, holidays through the years), start with an album that can expand later. Good luck!
