2014 Reading Olympics discussion

One of the most important aspects of a spy is attention to detail. In the absence of attention to detail, my occupation would have died out a few centuries ago.

In between spy missions, I've taken to golfing in my free time, and I've invited all of you to join me. Along the way, we'll be testing how attentive and detail-oriented you are. We'll be doing that through...a cover challenge!

Below is a list of 18 requirements - 1 for each hole of the course. Each country must choose 18 books whose covers meet a requirement. You may not use a book more than once and must PM your completed lists to me. Get searching!
1. A book which has a hole on the cover
2. A book that centers around a sport
3. A book written before the 1900s
4. A book that takes place on a different continent than your own
5. A book that has someone wearing green on it
6. A book that takes place primarily in nature
7. A book which has less than one hundred pages in it
8. A book that has birds on the cover
9. A book about a spy agency
10. A book that involves traveling to a different country
11. A book that features someone who switches sides (for example, a backstabber)
12. A nonfiction book about someone who was a spy
13. A book which has any country’s flag on the cover
14. A book that has blue on the cover
15. A book which is about fresh starts
16. A book that has a government leader on the cover
17. A book which features a well-known building on the cover.
18. A book with anything golf-related on the cover

Can we use books in the same series for two of the answers?

Yes, as long as you do not use the same book twice

Thanks :)

Is there a time limit, like fastest team wins, or is it just who has the "best" list?

Whoever is closest to accuracy wins (so the latter option).
