It would be great if this feature was extended so that I can sync my books across different Calibre installations on different machines.

Can't you just put your library and database on git or Dropbox? It should just work, unless you're accessing them from two devices at the same time.

Wouldn't that trigger copyright defender algorithms and cause your Dropbox account to be suspended?

I love it in principle but, considering how small most books are relatively to storage space offered by modern devices, even mobile ones, what is the upside of storing content centrally instead of just carrying a copy with you?

I used to COPS on my nas. I would add books using calibre, stored on the nas, and served up via COPS. Many apps (I used FBReader) have OPDS capabilities. This is a sort of online catalog which your reader can browse, search, and download books from. I almost never used the online reading feature, but did utilize the catalog concept quite a bit, especially when switching devices. I had a rooted Nook that had both FBReader and Kindle reader installed, giving me a sort of "best of three worlds" reader. I did have to "page sync" manually. I would do this by memorizing a sentence or phrase on one device and then search for it on the other device.

I do, with Dropbox, and it mostly works... but it's very easy to get the database corrupted even if you are careful not to have more than one instance of Calibre open. I haven't tried using a source control system, that might work better. Hmmm. And of course that only works for computers, There isn't a full version of Calibre for Android.

Out of curiosity, how does your DB on Dropbox get corrupted if not by having more than one instance of Calibre open?

I'm asking because I use Dropbox to store my Keepass DB, and so far (2+ years) I haven't had any problems.

I've always just used Calibre because it's a nice way for me to strip DRM and then archive my books. I've never really used it any kind of active way. Since I buy pretty much everything from Amazon, I already effectively have a content server. Does anybody have a link to an online server (with public domain books)? I'm curious to see what the presentation is like. What's the typography like? Does the screen dim after…

My response is to avoid buying ebooks from Amazon if possible.

Most of my purchases are from Weightless Books [1] which sells only DRM free books and magazines.

Granted, this is a limited and small market (SF related stuff) but if I have a choice of getting a book DRM free from a vendor or getting it from Amazon, I would avoid Amazon, even if its price was cheaper.

I don't know. But I occasionally find files with names like foo(username's conflicted copy).db.

I do the Keepass thing too, and this has happened with it's files as well, but that doesn't seem to cause any problems.

Many of my ebooks are anywhere from 50 to 350 Mb. That adds up when you want to load many of them. The downside of course is that you need a good Net connection, unless the Calibre Content Server can be configured to do some kind of 'trimming', while serving the ebooks over the wire. Also a content server mitigates you having to manage and synchronise your ebooks in multiple places. You only need to manage one librar…

Why are your ebooks so large?

They contain a lot of colour images and diagrams. Books on biology and art. Granted other topics including fiction are usually in the ballpark of a few megabytes.

How do you differentiate between DRM-free and DRM-protected books on Amazon? Up until I have read this comment, I didn't even know that Amazon support DRM-free books.

Tor doesn't put DRM on any of it's titles. For an example, look up Cory Doctorow's book Walkaway. At the bottom of the book description it says:

> At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Unfortunately, they don't always tell you. If you look up Little Brother (another of Doctorow's books), it doesn't say anything about DRM even though the book doesn't have DRM.

I do with Dropbox too, along with a portable version of Calibre. For syncing to my andoid phone, I use [Calibre Companion](https://play.google.com/store/apps/details?id=com.multipie.c...).
