42. What have you learned?

It's been a long year, thinking back to January when we started this program seems like a long time ago. We've had some easy lessons and we've had some hard lessons.

For your very last lesson I'm going to make you think, I have four questions I'd like you to consider and answer in the comments.

1. What was the most useful thing you learned?
2. What was the most fun?
3. What would you like to learn more about?
4. Which do you think will have the most impact on libraries?
