Note on Using Papers with Web of Science/Web of Knowledge
Please note that as of September 30, 2013, there is a known issue using the Papers app with Web of Science that will be addressed in a future update to Papers. As a workaround, you can use the Papers bookmarklet to import articles from the Web of Science website to your Papers app.
