For several years I've liked using
The Postal Service Guide to US Stamps as an alternate to the Scott Catalog. I use both but like having a choice available.
Scott numbers are used and Scott catalog prices are listed.
Here's a link to what this book looks like:
https://shop.usps.com/webapp/wcs/st....ac=S_891000I like that the book is spiral-bound so it lays flat when you're using it. Pictures of stamps are grouped on one side so that you don't have to leaf through pages and pages of stamps to find the one you're looking for. Back of Book items are included as well. It weighs about half of what the Scott Specialized catalog does.
Older editions can be found on
ebay and
Amazon. My most current edition came from
Amazon as an ex-library copy.
