Borrow books: Amazon testing Kindle rental service

Speed readers rejoice: Amazon seems to be testing out a new rental service for books.

The Seattle retail giant already has a textbook rental service that it debuted in July 2011. But Engadget just noticed a non-textbook available to rent called The 5 Elements of Effective Thinking. While the title is published by Princeton University Press, it’s not exactly a full-on textbook and could be an indication of Amazon testing out a Kindle rental service for regular books.

Rental prices start at $5.50 for 30 days and slowly increase for every day thereafter until you reach the full retail price of $9.99.

There are very few, if any, other books that allow for renting. Time will only tell if Amazon pushes this out for other titles.
