A Bug's Life

I have a huge heap of bits of paper with recipes (tried/not, clippings from newspapers, scribbled notes, multiple-dish dinner party menus, 30x30cm to 2x3cm etc) and I could do with sorting them into some useable format. Can anyone recommend a system? I'm not averse to typing things into computer (but that would take ages), or pasting things into a book (except where clippings are double-sided). Hard-bound book? Loose-leaf ring binder? I'd like some sort of index to help me find things - maybe by categories like dairy-free-ness, calorie count, course (starter, main, dessert), cuisine (Chinese, Indian, Spanish etc), or ingredient. I would like to store information on calories and suitability for restricted diets (no dairy, no gluten, veggie, vegan).

This must be a solved problem - would anyone like to suggest something that might work? Or suck air through their teeth and say "You don't want to do it like that..." Or just tell me I'm doomed to have an ever-increasing unsorted heap? Or tell me to declutter and chuck the whole lot out - it's not like I can't cook and don't have a decent collection of recipe books already...
