The phenomenon of "Blogola" has recently come to my attention (thanks to this morning's Wall Street Journal). If you are involved in marketing for publishers or booksellers, I would be happy to accept old books, or new books related to old books, regarding the subjects listed at the top of this page. A trip to a venue such as the Frankfurter Buchmesse (e.g.) also accepted.
If you represent the tea or lemon industries, we can discuss other possibilities. In return, I will consider mentioning your product to my readers, who currently number in the seven figures (assuming the first six figures are 0). Thank you.
