I’m not sure if it’s a browser or Zotero issue on my end, but the copy of “Topic Modeling By Hand” in the group documents was not loading properly. I had a similar display issue when I tried to “print” .pdf copies of Debates in Digital Humanities at the beginning of the semester – perhaps it’s a limitation of the comment-friendly format DHers seem to prefer.
Alex, the file may not work, as the .pdf/print function doesn’t work well translating the site’s plug-in content into a static document. But the original url, as listed in the Zotero metadata for “Topic Modeling by Hand,” works just fine. If you’re having trouble with your browser displaying that content, you might need to switch browsers.
