Digital Text Platform lets you upload and convert your content from several formats. However, for best results, Amazon suggested that you upload your content in HTML format, as Amazon DTP converts all uploaded content into HTML first.

Followings are some highlights of Amazon’s agreement:

5. Royalties. Provided you are not in breach of your obligations under this Agreement, we will pay you, for each Digital Book we sell, a royalty equal to thirty-five percent (35%) of the applicable Suggested Retail Price for such Digital Book, net of refunds, bad debt, and any taxes charged to a customer (including without limitation sales taxes) (a “Royalty”).

6. Payment Terms. We will pay Royalties approximately sixty (60) days following the end of the calendar month during which applicable sales of Digital Books occur. We will, concurrently with payment, provide statements providing detail regarding sales of Digital Books and corresponding Royalties. All payments will be made in U.S. dollars via Electronic Funds Transfer (“EFT”) payments. You will not be permitted to register for the Program without providing a valid U.S. bank account number to receive EFT payments. We will accrue and withhold payments until the total amount due is at least $10, provided, however, that we may make a payout of all accrued amounts at any time in our discretion. All statements shall be conclusive, final and binding, unless Publisher gives Amazon written notice stating the specific basis for objection within six (6) months after the date rendered. You shall not maintain any action or proceeding against us in respect of any such statement unless you commence that action or suit within six (6) months following the date that you provide Amazon with the written notice referred to in the immediately preceding sentence. Any such action or proceeding shall be limited to a determination of the amount of monies, if any, payable by Amazon to you for the accounting periods in question, and your sole remedy shall be the recovery of those monies with no interest thereon.

7. Taxes. We are responsible for collecting and remitting any and all taxes imposed on our sale of Digital Books to customers. You are responsible for any income or other taxes due and payable resulting from amounts owed to you by us under this Agreement. Accordingly, unless otherwise stated, the amounts due to you hereunder are inclusive of any taxes that may apply to such payments. We maintain the right, however, to deduct or withhold any and all applicable taxes from such amounts, and the amounts due, as reduced by such deductions or withholdings, will constitute full payment and settlement to you.

8. Rights Granted. You hereby grant to us, throughout the term of this Agreement, a nonexclusive, irrevocable, worldwide right and license to distribute Digital Books as described herein, such right to include, without limitation, the right to: (a) reproduce and store Titles on one or more computer facilities, and reformat, convert and encode Titles as Digital Books; (b) display, market, transmit, distribute, and otherwise digitally make available all or any portion of Digital Books through Amazon Properties (as defined below), for customers and prospective customers to download, access, copy and paste, print, annotate and/or view online, including on Portable Devices; (c) permit customers to “store” Digital Books that they have purchased from us on Amazon’s servers (“Virtual Storage”) and to re-download such Digital Books from Virtual Storage from time to time; (d) display and distribute (i) your trademarks and logos in the form you provide them to us as part of your Application or within Titles (with such modifications as are necessary to optimize their viewing on Portable Devices), and (ii) other limited portions of Titles, in each case on and through any Amazon Properties and solely for the purposes of marketing, soliciting and selling Digital Books; (e) use, reproduce, adapt, modify, and create derivative works of any metadata that you submit as part of your Application for the purpose of improving categorization, recommendations, personalization features and other features of any Amazon Properties; and (f) transmit, reproduce and otherwise use (or cause the reformatting, transmission, reproduction, and/or other use of) Titles as mere technological incidents to and for the limited purpose of technically enabling the foregoing (e.g., caching to enable display). In addition, you agree that Amazon may permit its affiliates and independent contractors, and its affiliates’ independent contractors, to exercise the rights that you grant to us in this Agreement. “Amazon Properties” means the website with the primary home page identified by the URL http://www.amazon.com/ , together with any successor or replacement thereto (the “Amazon Site”), and any other web site or online point of presence, on any platform, that is owned or operated by or under license by Amazon or co-branded with Amazon (such as http://www.borders.com/ , http://www.waldenbooks.com/ , and http://www.target.com/ ), and any web site or online point of presence through which any Amazon Properties or products available for sale thereon are syndicated, offered, merchandised, advertised or described. “Portable Device” means any portable device that is capable of supporting the electronic purchase, display and/or management of digital text, graphics, audio, or video and/or other content.
