I have recipes from the last 30 years ripped out of magazines and newspapers. The ones that are just single recipes are easy to organise but what do I do with the multiple page spread on "Coconut" (savoury and sweet) or "thai cooking" or a specific chef??
I use a 40 page display book from Tesco, £3 but half price at the minute, each page is like a poly pocket and you can insert more than one page. I usually put an index page in the first page and number the pages. It is A4 size and fits along side my bigger recipe books.
I have a similar folder to Redpriest, and have one for sweet and one for savoury (and a third one containing takeaway menus, local leaflets etc). Mine are not in any particular order, just as I got them.
If it is a few magazine pages on a topic eg BBQ they go into one plastic page not separated over a few pages. I have 4 books, one is vegan recipes, one family recipes, a soup one and a dessert one, 40 pages give about 76 recipes as pages go in back to back, but the magazine spreads go into one page so just about 36 in the book as I use first page or two for indexing.
I have 80 pocket folders like red, one savoury and one sweet/bread. Though nowadays I do lots online at Eat Your Bboks - you can save indexed online recipes plus 5 books as part of a free subscription.
I use an app- website called Pepperplate which is brilliant and means I don't lose any recipes ever. I tear out recipes and then type them in. If they're online, which they often are, it takes seconds to copy and paste
Put them in plastic filing sleeves and ring binders. Three binders - main meals (lever arch file), normal ring binders for cakes etc and other (drinks, jams, pickles etc). Main meals has dividers for poultry, meat, fish, veggie. Sweet has dividers for large cakes, individual cakes, puddings, biscuits, savoury bakes. No indexing needed. Even if I look them up online I tend to print them and stick them in files, I CBA to faff with my phone while cooking unless its something very simple. I just get the main file out when I do my menu planning/shopping list and take out the recipes for the week.
