Long Term Preservation

What is the future of publishing?
It concerns me as a citizen and a librarian that we could lose history. So much material is not being purchased and housed in print format. It's digital. For access or current and up to date material this is second to know but what if you want something more than 10 years old?
We are not purchasing hard copies of materials and they dissappear out of the digital world with the passage of time. Not sure how it will work out.
I am working on a cataloging project to get a collection of old vinyl albums into our OPAC. This past week I have been looking at some that are historically significant for example Ed Murrow commenting on WWII. This isn't something you can look up many places. Items like this reflect the opinions of the world at the time events occured. Several volumes of commentaries about JFK are also available. Again commentaries about the perceived effect of the events as they were happening. A lot of insight is available here. How are similar things saved now. Will there be enough archived or preserved material to save our history?
