Trying to get some maps.

Is there a way to view all the maps a source book includes before buying said source book? If not, what source books would you recommend me buying to give me access to lots of snowy maps? I’m talking snowy forest, open snowy fields, snowy villages, mountain peaks, all sorts of stuff like that. I want to run a snowy campaign but I don’t want to use the same two maps over and over again with different decorations to try to make them look unique. Also, preferably maps in the same or a similar art style as the basic maps included with DnD Beyond or in books like Monsters of Drakkenheim. But if there aren’t any, cartoonish maps like the ones from Flee, Mortals are also fine.
