I have been collecting DC Rebirth comics every week for the past year and a half. I am storing them in poly bags with coated boards. I know all about Mylites and have already burned through 4k of them for my older 80s and 90s books. My question is I know older books yellow pages if not stored correctly but what happens to Current books with the magazine pages? How do they degrade and is it worth it to put them in Mylar right away? Do modern books hold up better now that they use different paper?
