I am guessing you have already found Amazon's Organizing Your Kindle Content. If every book on your devices is from Amazon, then you can do some organizing at 'Your Account' > 'Manage Your Device' > 'Your Kindle Library' or by using the cloud. If you have works from anyplace else, then the prospects get worse.
I personally have some OCD issues that ...
As a general principle, no. But most software vendors provide compatible apps for PC/Mac/Android. So if you will be happy using their reader app, you just install their apps and get synchronization across all platforms.
For instance, I don't own a Kindle, but I buy ebooks from Amazon and read them on both Kindle for PC and Kindle for Android
The same is ...
Try the Bluefire reader ( http://www.bluefirereader.com/ )
I had to switch to Bluefire from Kindle after getting a windows 8 tablet since the win8 kindle app doesn't allow sideloaded books. Bluefire on the other hand has apps for ALL the major ecosystems (ios, android, windows). In order to sync between devices you will need to set up a free adobe ID ...
My own experience with this is that with Amazon you have a couple sets of collections. My iOS and android devices seem to share a set of collections that are automatically sync'ed across them.
In contrast my kindle device and my (mac) desktop software don't share the same. However, from my kindle device if I look at my "Cloud" items, then in the overall ...
Moon+ Reader can do this, storing the data in Dropbox or in Google Drive.
(Note: I have not actually tried this functionality myself as I can't bear to use Moon+ due to its horrible UI and poor support for the ePub standard. But the feature is there in the settings, if you can find the right settings page...)
Google Play Books does so too - but it does not ...
OK, I've solved my own question!
It seems that all three books were free downloads.
So I've downloaded them again to my tablet, at zero cost.
I still think they should have appeared in the library automatically ......
Google books which was mentioned by a previous poster is a decent option, but it can be irritating managing your files on the google cloud.
If all you're trying to do is sync your last-read position between devices I would recommend Bluefire Reader paired with a dropbox account. You'll also need to set up a free Adobe ID and register the Bluefire apps on ...
I think I see the problem (or one problem at least).
I have a massive set of collections on the kindle app for android. (Like 50 collections holding 2000 or more ebooks).
But when I install the Kindle for PC app for my Windows desktop, it does not let me import the organized collections from the Kindle app for android. When I use the Kindle for PC app, ...
There's a way, but it's kinda tricky.
There's a bunch of android apps which sync the progress across the devices (like Moon+ Reader). So, if you can set up an Android emulator on your Linux machine, that should do the trick.
I believe this is a bug. Three people have reported this problem now:
Not sure how Amazon handles bug reports.
Here's my two cents.
First, this may not be what you want, but it's fairly easy to stock an ipad/ibooks with epub files. You can either email them to the account owner's email account or put links to it on a web page and just access the files from a browser on the ipad.
An alternative to upload the kindle files to your Personal Documents feature so it ...
You didn't mention if you wanted to do this over the network or over USB.
I've personally used the following approaches:
The Kobo app automatically syncs directly with the Kobo device when you attach the device to a computer using a USB cable.
I can copy ebooks files directly to my Kindle and/or Android phone when attached to my computer using normal drag-...
