Fontaine, J.-M.; Illusie, L. p-adic periods------Does any one have the following article?
It seems clear that there is no online version available, but a library can probably get a PDF copy through interlibrary loan if that's an option for you. The detailed listing is here. Note too that Milne's short MathSciNet review of this two-author survey concludes with the remark: "Except that it is more detailed, and does not discuss proofs, it covers much the same ground as Illusie's Bourbaki talk ...", which is freely available online here. Good luck with your search.
The desired paper is freely available on Fontaine's webpage! Here is the first part, and here is the second.
