Lowenstein Associates has put up a number of books on Amazon that were formerly out-of-print. Some examples include:

• Deborah Camp (A mix of contemporary and Old West Historical romances...over 40 coming in the near future, but here is a list of 10 or so available now)
• Lorena Dureau (Historical Romance: American Colonial South and West. Very Sexy)
• Dan Streib (thrillers with a James-Bond-meets-Anderson-Cooper main character)

(Descriptions taken from Meredith Barnes' blog here) 

AND if you spread the word about these authors, literary agent Meredith Barnes has offered to critique your query letter! An awesome opportunity! So tweet and blog away :).
