I just purchase an enlarger and it came with tons of paper. Some is quite old (not dated) but can anyone give me an idea of shelf life and if these are worth keeping
These are in sealed boxes
Agfa Record Rapid, Agfa Brovira Speed, Agfa Portriga Speed
There are also stacks of boxes of various Ilford multigrades mainly III and IV

I suppose on wayof telling would be to try it but was hoping for some ball park figures.
Phil I have some silver paper that has been with me for more than 5 years and still shows no signs of fog. If the paper has been kept at room temp with no extremes, it should still be good. If you get a little fog, add some potassium bromide or benzotriazol and it should work. Happy printing...
Like Jorge says, you should be fine for the most part if the boxes of paper were stored "properly". Of all your paper, I think the ones most suspect would be brovira since it is developer incorporated.
That said, I sometimes use some handed down agfa rapidtone paper bought in '93 and it shows no sign of fog.
Some of the old Agfa papers have a very long life in my experience, far longer than modern papers. I don't expect the "speed" papers to last particularly well, but if the Record Rapid is fibre based you could be in luck.
I've got both Record Rapid and Brovira fibre papers that are at least 12 years old. Record Rapid has not lasted well and needs benzotriazole to perk it up but the Brovira has stood up quite well.
Some of it is still as new. some is slightly fogged, but can be used with a little extra KBr of benzotriazol in the developer. Alternatively I can consider it pre-flashed and do no changes. Some of them are great for lith printing, even if they didn't work when new.
A very few (mostly KODAK) are completely dead, and seem to have no light-sensitivity whatsoever.
I recently ran across a nearly-full and sealed box of Multigrade in my garage -- must be at least 4 years old, probably around 7. Top half of the box: fog. Bottom half: okay-ish. Should have been in a dark place the whole time, could it have been fogged by Hawaiian weather, or... ? Hmmm. Either way my confidence is low, I wrote "Emergencies Only" on the box and put it back on the bottom shelf
