Microsoft has a big catalog of romance e-books up on their site, all in the Microsoft eBook format (.lit). (NOTE: site is getting a LOT of traffic and is slooooow).
Some folks are alleging that the linked files can be had for free, though you do have to get the Microsoft reader to actually read the files themselves. Others attest that there is a fee for each ebook, and links to various locations to purchase the ebook itself. Amazon listed A Knight in Shining Armor at $6.99 for the .lit version.
I have not had any luck scoring myself a free ebook copy of any of the listed titles. I shall have to keep trying. Mwaahahaha.
That said, I confess myself still largely ignorant of the ebook world. Anyone know if the featured authors, like Nora Roberts, Susan Elizabeth Phillips, Jude Devereaux, and Elizabeth Lowell gave their OK? Do they even have to have to give their permission to have their books encoded in a vendor-specific ebook format? And what do you ebookies think of the .lit file format itself? A complete flash in the pan, or the beginning of the MS-standard for ebooks in the future?
