Published on Nov. 15, this blog post by Brewster Kahle has been read by many and if you haven't read it, you should. Kahle begins by writing:

Ever try to read a physical book passed down in your family from 100 years ago?  Probably worked well. Ever try reading an ebook you paid for 10 years ago?   Probably a different experience. From the leasing business model of mega publishers to physical device evolution to format obsolescence, digital books are fragile and threatened.

He then goes on to talk about what the Internet Archive and others do to keep Digital works available and accessible. Yes, it takes a concerted effort of people and machinery, and that requires money. 

Looking back at my own blog posts, I know that I've written about digital preservation for a LONG time. It is not my constant focus, but I'm glad it is the focus of other folks who have the knowledge and fortitude to help our digital assets last for years to come. If you are able, support their work...if by no other way than helping them make the need for the work visible.
