Hi John, similar doi problem here. My configuration is: - Windows 10 - GNU Emacs 24.5.1 (i686-pc-mingw32) of 2015-04-11 on LEG570 - Miktex (up-to-date) with pdftotext v0.32..0 - org-ref v 0.5.0 (from melpa) Running pdftotext from the command line works and produces a text file with doi info. Let me know what I can do to help to test things. Thanks. Andreas PS: Thank you for org-ref ... an awesome Xmas present! On 24 December 2015 at 08:00, John Kitchin wrote: > Thanks!
