Those ~1200 odd files were exactly what I wanted at the time. If you look closely, you'd notice that each file is exactly one chapter.

The reason for this is that the PRS-505 had an old implementation of mobile DE, and the device itself was extremely slow. Having a file a chapter meant I could use the following XML in my toc.ncx:

<navPoint id="dbcd5ce5-df26-43df-987b-898896727659" playOrder="5">
        <navLabel>
          <text>CHAPTER 2</text>
        </navLabel>
        <content src="Sony Bible Project HTML Final_split_3.htm"/>
      </navPoint>

Notice the lack of fragment ID's (#chapterx) in the src line? The PRS-505 absolutely chokes on those when generating its TOC list.
