Clicking the "Save to Zotero" button on the Chrome toolbar frequently fails to get the pdf. This problem seems to be increasing rapidly, perhaps because more publishers are using their own pdf viewing solutions instead of the browser solution?
Due to #1, I now just download the pdf and drag it into Zotero, and let Zotero fetch the metadata. But this involves lots of additional clicks for each article.
Yet when I click the pdf link, the publisher version shows up in my browser. When I then click the Zotero save button, it *still* saves the open source version.
