The espionage of the Black 19?

One of the comments of Mystimus' blog pointed to Robert Ludlum.  It started as a joke, I tweeted a comment about Jason Bourne being a lot like our favorite amnesiac.  I thought it was a total wagtail.

Then I saw one of his books mention Salonika in the summary page on amazon.com. On a whim, I googled "robert ludlum dahomey" and got a hit.  And I kept getting hits for the most of the other locations. This list may be incomplete and some may be incorrect, please let me know if you see something I missed.

1. Dahomey- The Janson Directive
2. Salonika- The Gemini Contenders (another drifting twins reference?)
3. Calais (Pas de Calais)- The Gemini Contenders, The Tristan Betrayal, The Prometheus Deception, The Sigma Protocal
4. Ypres- no mention that I can find yet
5. NV- Nevada in The Aquitane Progression
6. Taranaki- no mention, but I did find a Ludlum's Valley in New Zealand.  New Zealand does make an appearance in The Matarese Circle
7. Odessa- The Odessa File
8. Galway- despite numerous mentions of Ireland and Irish in several of Ludlum's books, no action takes place there in any of his books.  Is that why nothing happened in Galway 1831? 
9. Bijapur- The Bourne Objective takes place in the capital city, Bangalore, of Karnataka.  Bijapur can be found in Karnataka, too 
10. Adana- no mention, but Turkey can be found in four of the Bourne novels and in The Hades Factor
11. Rio Negro- The Sigma Protocol 
12. Barkol- no mention that I can find yet 
13. Tangier-  The Janson Directive mentions Tangier Island, Virginia
14. B___-  mentions a "B-team" in The Lazarus Vendetta
15. Los Angeles- The Lazarus Vendetta
16. Tripoli-  The Prometheus Deception, The Hades Factor, The Janson Directive
17. Berlin/Danzig- Berlin in The Scarletti Inheritance
18. New York- The Ambler Warning (there may be others) and it should be noted that Ludlum was on the NYT bestseller's list several times. 
19. Toronto- The Lazarus Vendetta
