Here’s the link to the book’s new PDF I exported this morning, including a number of repaired typos and other fixed minor glitches:

There’s a weirdness here that I still don’t fully understand. If anybody out there can explain this to me, I would be tremendously thankful.
Ok. The release of 10-21-2025 was 20.2 MB in size. The release before that, from 9-13-2025, was 5.7 MB. I was in a rush to get the 10-21 release uploaded, and didn’t stop to look at file sizes. My bad. I live a fullish life and sometimes I move too fast.
I don’t claim to be an expert on PDF internals, so I did some digging around in the document properties for the 10-21 PDF. In the Document Properties there’s a button to bring up something called “Audit Space Usage.” This lists all the various components of a PDF, including images, fonts, and so on, with percentages of the file taken up by each component. The “Structure Info” component took up 70% of the PDF. I didn’t find anything useful about the Structure Info component online, and don’t really understand what it refers to or how it got into the PDF. The PDF I exported this morning has zero space in the Structure Info line.
It has nothing to do with it being a tagged or untagged PDF. (I tested that. Tagging adds a little bulk—just not 300%!) In truth I still don’t know why the 10-21-2025 issue is so huge. Some switch somewhere must turn on Structure Info, but I haven’t found that switch yet, and must have hit it accidentally before I exported the 10-21 PDF.
Many thanks to reader Robert Riebisch for alerting me to the oversize file!
