Regarding sketchbooks Leonardo da Vinci advised his students to "make a note with a few lines in a little book you always carry with you ... these are not things to be erased but preserved with great care, because forms and actions are so infinite in number that the memory is not capable of retaining them, therefore keep your sketches as your aids and your teachers.
