In the company's continuing effort to make the Kindle file format the de facto standard for electronic books (which should not be allowed to happen, given how inadequate the format is for anything but straight text), Amazon.com has launched "Kindle for the Web," which lets site owners embed Kindle book previews on their sites. Realistically, Kindle for the Web is just a way to encourage people to preview the first chapter of a Kindle-format book in a Web browser, after which they can purchase the ebook for reading on a Kindle device or in Kindle software on a Mac, iOS device, or Windows-based PC. It's a smart move on Amazon's part, and notably different from how Apple has restricted access to the iBookstore to the iBooks app. follow link
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
