I found this homemade address book at a thrift store. It has a wood front and back that is lacquered with a picture and the word "Addressory" (I looked the word up in the dictionary- it's not there).
There are photocopied photos separating each section. In the photo below, you can see it says "AB" in the upper right hand corner. There are 10 dividers in all. There is also a quote on each divider. The one below is by Emily Post and says,
"Love in a letter endures forever in our memories."
The next few pages are form sheets with spaces for addresses as shown below. What's nice about this is that you can easily add more pages as the need expands.
While I like the concept of the handmade address book, this one looks outdated with its faded pages and photocopy photos. If I were to create one from scratch, I would use colored scrapbooking papers which are heavier, fun letter/mail images from Pinterest, un-decorated address pages so that they're cleaner, possibly room for photos of each recipient or fun stickers.
