Proprietary format for mymustreads.com
#1  stevecoh1 07-21-2020, 04:02 PM
I have a kindle paperwhite but it's getting harder and harder to hold a charge. So I want to replace it. Amazon offers me a discount on a replacement and I'm looking at the Oasis, which I would go for except for one thing. I don't actually like being locked into Amazon's prison. There are alternative e-book vendors. One I've looked at is mymustreads.com, which seems to be a collection of independent bookshops. I'd much rather support such an entity than amazon.com, if possible. These folks offer e-books, but in some sort of proprietary format. I wrote to ask them what this format was, and their reply was unsatisfying to me, a calibre user.
Thank you for supporting your local bookstore!
All My Must Read titles are in a proprietary format and must be read via the app or website.
Well, I don't want to move from amazon only to be locked into some other proprietary format!

Does anyone on this forum know what this format is, and whether it can be converted to read on kindle?

If so I can buy a new kindle and be done with it. Otherwise, I would perhaps choose something like the IPad Mini (which would have kindle apps and this new proprietary app) to read on, though I prefer the kindle for battery life.

mymustreads uses an app that you have to use. You cannot read the eBooks on a Kindle.

But, you can remove the DRM from ePub eBook (not B&N and Apple) and convert those to KF8 for your Kindle.

You just need to go to https://apprenticealf.wordpress.com and install the DeDRM Calibre plugin. If you need help using it, ask at the blog.

Not sure I understand your reply. Are you saying that there is no way to convert mymustreads books to be read on kindle

OR

are you saying that with this plugin in Calibre, I could convert such books to be read on kindle?

You can't install the necessary app on an e-ink Kindle. You'd have to install the app on a pc or Mac, assuming they offer an app for those systems.

Then you'd need to run Calibre with the mentioned plugins, and get the book files from your pc app into Calibre. Once the drm was removed, the book can be converted to a Kindle format and placed on a Kindle for reading.

I don't know, but I'd be surprised if a format only used by one small web site had been reverse engineered and so could be read on an E-Ink Kindle.

The FAQ's for that sites indicate only Android and iOS apps, no apps for downloading to a pc or Mac. It looks like you can read on a computer via a browser, but that wouldn't download the book.

As far as I know there is no way to retrieve a book file from an iOS device, from any reading app. I don't know about android.

The only way to use Calibre is to get the actual book file into Calibre. You can't do that if you can't liberate the book file in the first place.

Seems like a small time operation. Why not stick with the major e-book sellers, Amazon, Kobo, etc? Just because Amazon "locks you in" doesn't mean you have stay with Amazon. I've used Amazon books on a Kobo, and Kobo books on my Kindles. It's not that difficult for someone with average tech know how.

I'm saying that the eBooks that mymustreads sell need to be read with their app. The app has nothing to do with Calibre and you cannot read the eBooks on your Kindle. It's some proprietary format used so you need the app. If you buy from mymustreads, you are wasting your money.

I am also saying you can buy ePub format eBooks from shops such as Kobo.com or eBooks.com and remove the DRM using a plugin for Calibre. Once done, you can convert the ePub to a format usable on your Kindle.

I doubt the eBooks can be converted to something that can go into Calibre to be converted to KF8.

Wasn't even thinking about that. If that proprietary format is that obscure, are the correct plugins even available? If they aren't, Calibre won't be able to format shift, even if the file can be accessed.

Edited for clarity.

Thanks for the clarification.

So the key point is that proprietary apps don't allow access to the underlying ebook file and therefore Calibre has no solution for reading mymustreads books on a kindle.
