We have access to that journal, but libaccess won't let me get to it.
Q: For some reason you can't get Acta Crystallographica papers via lib access. For example: "To allow http://scripts.iucr.org/cgi-bin/paper?S0567739476001551 to be used in a starting point URL, your EZproxy administrator must first authorize the hostname of this URL in the config.txt file.
Within this database's section of config.txt, either the following line must be added: Host scripts.iucr.org or, alternatively, a RedirectSafe for this host or domain may be appropriate.
After editing config.txt, the EZproxy server must be restarted to make changes take effect."
