AFAIK you just need to check the object type and stream length. See here:

I've tested both books with Calibre, it can not show or transform none of them. The unscrambling method described on sven.de/librie is exactly the same I implemented in LRFTools, but for some streams it does not work.

I'm going to pm you the books.

The following code

        BYTE keybyte;

        declen = LengthOfStream
        keybyte = (declen % PsuedoEncryptionKeyByte) + 0x0F; 
        if ((type == 0x11)||(type == 0x19)||(type == 0x17))
        {
            if (declen > 0x400) declen = 0x400;
        }       
        for (i = 0; i < declen; i++) {
            *(p + i) ^= keybyte;
        }

sometimes produces a byte stream (p) wich is not a zip-encoded stream. As keybyte holds 256 possible values, I've test each value trying to unzip resulting streams. If one of them works, I suppose this is the correct keybyte an continue. This weekend I'll try to figure out how can be the keybyte be infered with these sample books directly, because I like to think LRFTools is a fast tools.
