How much trouble is it to store and care for these? I know, they can be somewhat fragile. Plus, isn't the grading different than that of comics?
I store mine using Golden bags and Silver Age boards. The Weird Tales books are not as delicate as most pulps, as the edges are evenly trimmed (most pulps are uneven with covers that over-hang the interior book, which causes folding/tears.)
Pulps are graded differently than comics, less strictly with Very Fine being the top grade, and almost impossible to find except with some bedsheet or production trimmed books. Even then page quality is usually yellowish to cream.
