What is a (public) library?

We have lots of conversations in my extended family about the role of the public library these days, and I happened across an interesting post from an unlikely source – the Kickstarter blog. In a post titled, Libraries are Everywhere, the author asks the following questions of four founders or employees of very non-traditional, yet public, libraries:

  1. What is a library? How would you define it?
  2. What's so important about libraries?
  3. What do all good libraries have in common?
  4. The year is 2050. What are libraries like in the future?
  5. What advice do you have for people that want to create a library of their own?

Nice to hear from folks outside the traditional fold.
