Today, I finished adding introductory sentences to all the quoted references in references_sonnet_1621.xml. In the process of doing this, I made sure to check that all the references in the references_sonnet_1621.xml file were tagged in the sonnet_1621.xml file each time they appeared. I found that I had forgotten to tag a lot of words that belonged under "humeur" but I've fixed this now.

I also had to add several note tags in the sonnet_1621.xml file to indicate spelling errors by the scribe. I think there are more of these errors, which are indicated in comment tags, but I'll need to comb through the text to make sure that I include a note for each of them.
