Finished marking up the last article for volume 18. When I came to upload it, I got the same duplicate node error we had last week; a restart of Tomcat solved it, but we need to watch out for this. If it happens frequently, we probably have corrupted indexes and we'll need to follow the instructions here to clear the index files.

Author corrections to two volumes came in, and I did those.

Also did the first build of the Volume 18 PDF. I'm doing this in my Windows VM, simply because that's already got XEP installed in it, and I'm not sure (after five years) whether it'll be practical or possible to obtain the Linux version of that particular XEP, which we purchased so long ago, and get it authorized. If ScanCan stays with us after this year, then we'll make a 5-year plan which involves a newer desktop version of XEP for Linux.
