Although it was written long ago, strong recommend for Dale Pendell's The Great Bay, https://www.goodreads.com/en/book/show/7821813-the-great-bay https://www.goodreads.com/en/book/show/7821813-the-great-bay It's a look over an exponential timeline of what goes down figuratively and literally after a collapse, with vignettes checking in during, shortly after, years after, decades after, ... etc. up to the thousand year scale; with nice interstitial montage scenes punctuating them describing what's going on around the world. It's set in CA and some of the "college tries" to keep things going are quite recognizable... ...one of the memorable take-aways is what will serve as hard blockers to continuance is lack of access to various rare elements required for e.g. batteries. Once re-use exhausts itself, absent global trade, it's game over. :(
