Over the past few years I've used Mnemosyne's A4 (model 199) or their B5 (model 194). I'm a medical student and write at least five pages of notes per day at minimum. About a year or two ago I found the Midori MD and loved its minimalistic design and was especially drawn towards it as it says "MD" on it. However, I can only find the A5 size available. If I'm not mistaken, they make an A4 MD notebook. Does anyone know where I can get my hands on one of those?
