Selling books to raise funds for a cause

Here's an interesting article about a psychiatrist who got into online bookselling to raise funds for her favorite cause, land conservation.

Here's an excerpt:

Books that people scramble to buy, and perhaps pay a lot of money for when they are released, are worth little on the Internet book market, she said. The ones she sells, she said, would often end up tossed away if she did not put them up for sale in an international marketplace.

“The most successful books are highly technical books about subjects I don’t understand, electrical engineering, metallurgy, nuclear science,” she said. “I sell a lot of books to Korea, Hong Kong and Australia.”
