I just discovered that there is in fact a proper HTML text of the FGS edition. Since I don’t have flash, when I go say here it gives me this error:
Sorry,need flash player. Get Adobe Flash Player it’s possible to view a simplified version of the book on any device, or you can view the mobile version here
Both of those links are broken, but it does suggest that an HTML version exists. So I tried using the search, and I found that that way I could get results in HTML. It appears as a popup
<div>, charmingly styled to look like a window in XP! There’s no URL for the search result, so it’s still not particularly accessible, but at least we know there’s something there.
