This probably isn’t the right sub forum to make this request, but I wasn’t sure where else it would really go.
Now that the BW books are available in pdf, I wonder if BWHQ would ever consider making them available in epub/mobi.
I’m getting older and being able to scale the text is very helpful.
I’ll preface that I am not part of BWHQ, but even so I doubt this is in the works because I suspect that the conversion to mobi would be a very large project for a very small company.
Now that the PDF is available, I would suggest searching for a decent PDF to mobi converter.
They’ll certainly have trouble with all the images in the book, as the margin art is a pretty unusual layout choice these days, but I think it’s probably your best bet.
