AC needed to generate a printable document of pages for a specific year, for the encoders to use. Got a list of images from the SQL XML dump like this:

let $images := //table_data[@name='poems']/row[starts-with(field[@name='po_date'], '1820')]/field[@name='po_images']/tokenize(., '\s+')
return string-join($images, '
')

Then used wget to pull down the images from the server, and generated the PDF:

img2pdf -o 1820.pdf *.jpg
