Congratulations on getting your first ebook done. It looks fine on my Sony 650.

I'll send a few comments by private mail.

Regards, Alex

Oops, I see you're not receiving private mail.

In your content.opf file there is
<dc:creator opf:role="aut" opf:file-as="J. C. Ryle">J. C. Ryle</dc:creator>

So far as I know the whole point of 'opf:file-as' is to enable data bases to file the ebook by author surname. I think you might do better to use
<dc:creator opf:role="aut" opf:file-as="Ryle, J. C. ">J. C. Ryle</dc:creator>

I know it's a matter of personal taste, but I think a 1pt left margin is too narrow. For what it is worth I use 3%.

Again, it may be personal taste (or I'm too set in my ways) but I was a bit taken aback by seeing XML files rather than HTML files. I don't use Sigil; I use an HTML editor. Is this what Sigil does?
