I've got an old fashioned box for my oldest recipes - stuff I copied from Mom when I moved out. But for my own collection, I started out with one of those "magnetic" photo albums, so I cut out the recipe and stick it in the book - the clear cover sheet also keeps the pages clean, or at least easy to wipe if spilled on. Then I added category dividers and 3-ring binder sheet protectors for full page items. I'm up to 2 volumes now. The funny thing is that about 10 yrs ago, I learned my sister came up with the exact same thing for her recipes - and we lived on opposite coasts and had never discussed it with each other.

Your tagging sounds cool though. But I don't think I'd have the discipline to get all my stuff converted. It took me years to type up the group of recipes that I regularly share so I wouldn't have to do it every single time.
