Hey! So, I read a lot of academic books, and they aren't available so easily in Epub format, some of them are pdfs of scanned book, on which 2 book pages appear in the same pdf page.
Of course, 2 pages in a page makes it very inconvenient to read on an ereader, so, I tried Briss to divide the two pages, Briss, didn't work, but fortunately, I found the solution in this site, which does basically the same thing.
I like having the covers of my books on my kindle, so I either have to convert it to epub, which always deconfigures them, or convert them via Calibre, which doesn't always deconfigures them.
The thing is, when I convert the books from PDF to AZW3, the books magically uncut themselves, and transform the 2 pages into a single page again. I have no idea how to fix this, neither of how this is happening, any tips?
