Among the information supplied to people that request a copy of their personal information held by amazon is their amazon supplied ebooks.
They send it all in a single zip file. Mine had over 2400 files and directories. ebook info, like other info, is spread across several multicolumn csv files. ebooks show up in more than one place and no file contains only ebooks since they are lumped in with other digital items.
Presumably someone could write a script or even calibre plugin to exploit the list any way desired. It probably isn't convenient to make new requests very often, but it may be useful for retrieving a large history.
As examples, Digital/Digital-Ordering.1/Digital\ Items.csv has:
Code:
ASIN,Title,OrderId,DigitalOrderItemId,DeclaredCountryCode,BaseCurrencyCode,FulfilledDate,IsFulfilled,Marketplace,OrderDate,OriginalQuantity,OurPrice,OurPriceCurrencyCode,OurPriceTax,OurPriceTaxCurrencyCode,SellerOfRecord,Publisher,ThirdPartyDisplayPrice,ThirdPartyDisplayCurrencyCode,ListPriceAmount,ListPriceCurrencyCode,ListPriceTaxAmount,ListPriceTaxCurrencyCode,GiftItem,OrderingCustomerNickname,GiftCustomerNickname,GiftMessage,GiftEmail,RecipientEmail,GiftRedemption,ItemMergedFromAnotherOrder,QuantityOrdered,ItemFulfilled,ShipFrom,ShipTo,IsOrderEligibleForPrimeBenefit,OfferingSKU,FulfillmentMobileNumber,RechargeAmount,RechargeAmountCurrencyCode,SubscriptionOrderInfoList,PreviouslyPaidDigitalOrderItemId,PreviouslyPaidOrderId,InstallmentOurPrice,InstallmentOurPricePlusTax,DigitalOrderItemAttributes,InstallmentOurPriceCurrencyCode,InstallmentOurPricePlusTaxCurrencyCode
Actually, the above file looks like the only one useful for building a list of books with titles, but note that none of the plethora of columns is author..
