 		<meta property="se:production-notes">Note that the Internet Archive have misnumbered the sources listed here. Volume 1 has the filename lastchronicleofb02trolrich and volume 2 has the filename lastchronicleofb01trolrich. / Note that find-mismatched-dashes flags ‘art-work’ in chapter 38 but this should be left as is (here it’s a verb not a noun) / Typogrify makes changes to datelines because of the obscured days of the month. Do not accept these changes.</meta>
