A question for all the paper experts.

If a prewar card currently shows no signs of foxing, does that mean it is "out of the woods" and foxing is no longer likely to occur, or could it still happen at any point? Also, does slabbing increase or decrease the likelihood...or will we not really know until we have cards that have been slabbed for 50 years?

Any direction on good paper conservation reading would be greatly appreciated.

Foxing primarily occurs due to sulphur content of paper that may either be in contact with the cards directly or humid environments where cards might have been stored within a bag or box made of such paper are putting off sulphur.

You might want to check out this website on "foxing". It is very informative.

Having seem lots of it I would say it is mostly because of the amount of the pulp or rag in the paper not really what the cards are being stored in . Not worth chancing in metal filing cabinets though like we did for years .
