Not personally, but I'm quite certain that my national archive will have microfiche of all of them.
Just like I don't need access to the original sources of the Persian works that underlie the maths I use on a daily basis, it's good to know that they are still available.
Just like with newspapers we can have a discussion if some of these things are worth preserving, but I don't want to make that call and decide what will be seen as important in a century.
