I review both physical copies that publishers send me and e-ARCs I request from Netgalley and Edelweiss.
From what I can gather, the physical copies aren't allowed to be reviewed before their release date ('embargo date'). I get them the month of or just after release.
Sometimes the e-ARC publishers request a timeframe ie no more than two weeks before or after, but more commonly I don't see any restrictions on when I can review them. I can receive these books months in advance.
I was under the impression that early reading copies were supposed to help build hype and awareness. Therefore I can review them as early as I want.
I'm a little confused as to why the big five wouldn't want any early reviews.
Is anyone else facing this issue?
