Married in a library, no. Buried in one? I'd like to write something that would do that.
Alas, our libraries here are in broken down retail space - failed shopping centres. If I were traveling I would love to visit those older ones in other cities. In Europe, I visit lots of older churches even though I'm a godless heathen, but in a library I'd be inclined to worship. There's something about the care people put into creating the spaces they put that which they respect in. Libraries, churches, mosques, museums - the buildings can be things of beauty.
If I were to travel anywhere in the US, it would be New York. I'd love to hit the museums and now after this, the libraries. It's a great city I haven't been to for a while (but have visited half a dozen times), and if or when the world changes, I'd happily go back. Traveling to cities is like reading books - rereads are good because if the book is more than just a plot, you find new things every time. Cities too. You can look for different things on every visit.
I think every time we read fiction, we merge some of ourselves with it in our minds. What we are concerned with in daily life becomes part of how we process the text, and what we see in it. You or I can read the same book and come away with different changes. I also think how we read a book changes as we age, and as we experience. I used to read for the story and the ideas. Then I read for the writing and language use. Now I find myself reading more technically, trying to see how. You don't know a fish til you've kept it for 2 generations, and you don't know a book until you've read it a few times, if indeed it's good enough to read again. You can't be in a hurry.
