Netgalley No Longer Using ACSM
Netgalley is switching to LCP format and you will need to enter your netgalley login. The device guide linked makes no mention of this format (and still has no info for Kobo users who sideload epubs)
I have never come across a LCP book myself and have no new books to download right now but remembered this from r/Calibre https://www.reddit.com/r/Calibre/comments/17oj5dt/is_it_possible_to_unprotect_a_fixed_layout_lcp/ so be aware if you use Calibre to manage books
