Amazon has numerous “secret weapons” as it continues to strive to make the Kindle Store the go-to venue for all participants — readers and authors alike — in the Kindle, er, the eBook Revolution. Among these, as we have noted before, are expanding commitments to publication of indie authors and backlist titles through programs such as

• the Kindle Digital Text Platform;
• Amazon’s CreateSpace POD and worldwide paperback distribution program;
• various Shorts programs;
• initiatives to invite successful authors like F. Paul Wilson, Ian MacEwan and Stephen Covey into more or less direct Amazon publishing relationships; and
• the company’s own AmazonEncore publishing house.

Today Amazon announced an interesting array of six titles that it will publish through AmazonEncore this Summer. All six will be published both in paperback and Kindle editions, so that their ebook editions will be available on the Kindle, the iPad, the BlackBerry, the iPhone, the Mac, the PC, and other devices for which Kindle Apps will be launched in the next few months.

Here’s the list:

• Elizabeth Street  by Laurie Fabiano
• Herb ‘n’ Lorna by Eric Kraft
• Double Bound by Nick Nolan
• The Berry Bible by Janie Hibler
• A King of Infinite Space by Tyler Dilts
• The Last Block in Harlem by Christopher Herz

AmazonEncore, still a tiny initiative after its launch less than 11 months ago with 16-year-old author Cayla Klaver’s previously self-published novel Legacy, nonetheless is charting an impressive growth arc with three titles released in February, four more this Spring, and six set for Summer. The actual Kindle Store release dates for the “Summer” titles fall in May, June,and July, and they are already available for pre-order.

The Kindle editions of current and future AmazonEncore titles are priced between $5.99 amd $9.99, several dollars less than the paperback editions. There’s no word yet on whether Steve Jobs will approach the AmazonEncore publishing house with an offer to carry the AmazonEncore titles in Apple’s iBooks Store if the publisher agrees to raise its ebook prices to $12.99.

Here’s the guts of this morning’s Amazon news release:
