I save mine as Word documents, which are filed in folders on my computer 'Mains', 'Snacks', 'Baking', 'Desserts', etc. I print out any I want to try and if I decide they are likely to be a family regular, I put that recipe into a plastic-sleeve display book. I need to give that a book a bit of attention now - I had to add lots more sleeves, so I need to divide it into the above sections for ease of use.
