Publishers Weekly revives the rumor that Amazon.com is working on its own e-book reader, one that will presumably be a strong competitor to Sony's electronic reader.

According to PW, Amazon has been showing off its reader to publishers for months. The head of Harper Collins in the U.K. even mentioned it publicly at the London Book Fair, the article states. The reader, rumored to be called Amazon Kindle, could reportedly be released as early as this spring. Amazon has so far refused to comment on any Kindle rumors.
