STASSHHHHH i love my old sketchbooks
but thats just my personal experience, i have a lot of affection for my old sketchbooks as i can use them to track my development and also reminisce on completed projects. but it sounds like your sketchbooks might be making you feel miserable? in which case, id say trash all but the best two
but before that!!! stomach going through them one more time with a scanner or nice camera, and scan / photograph all the good life drawings and other stuff - maybe even scan the entire sketchbook and make digital versions if you want. thesell be really great for a portfolio - not just useful for art school, but also art jobs. thats also why you should keep the best two; to show to potential employers and the like.
i have a friend who did an entire project on like, memory & the rainforest and made two whopping sketchbooks worth of work. for her final piece, she shredded and pulped it all and made an entirely new sketchbook. in the pulp was a lot of ink and bits of fabric, so the paper is grey and delicate, but its also a really cool artefact in its own right.
the big boys are stacked on a shelf in my closet, the small boys on my bookshelf. my oldest sketchbooks, from highschool, are really atrocious and ill throw them out this summer when i move - maybe burn em if im feeling like a ceremony. but i kept them to cut all (aaaaaaall) the extra blank pages out for further use.
reasons to keep:
- projects youll revisit
- good examples of your practice
- places to store test pieces
- sentiment <3
- to remember what you did & how you did it
but then i approach my sketchbooks largely as workbooks for various projects; i have my sketchbooks for each of my comics, my sketchbooks for my college projects. theyre full of research, tests, and thumbnails rather than life drawing and standalone sketches. i do most of those in little A5 sketchbooks, though i do that very rarely these days tbh.
reasons to throw:
- reminds you of bad shit
- contains bad shit
- ran out of space
i like ceremoniously burning things, but be careful! theres also the pulping thing i mentioned earlier. besides that, i dunno, id just bin em
