My experience is that different papers have different keeping qualities...
all keep better in the cold weather than hot. (In summer John Dugdale
keeps his in the refrigerator.) All keep better if you stack them under
weight in a box, so they have as little air contact as possible. If
you're choosing between papers, you might test them in advance. As I
recall, some will print darker, others will print flatter if kept more
than a day or two...
But the time they've been kept may affect exposure time... so check in
advance.
