Your plugin looks excellent! But before I install it I would like to know how it behaves if there are no citations? I would prefer that in that case it shows nothing, including "Cited by" title.

[Tadas]

if there is no citation it shows nothing, for example this one has no citations: http://www.btp.vgtu.lt/index.php/btp/ar ... tp.2011.01

Is there a web page which contains link to download latest version and get more information for the plugin CrossRef CitedBy?

Hi thebigaym,

This is the only place you can get the plugin, currently.

Hi Tadas!
I tried to use Cited-by plugin in OJS 2.4.1, but apparently it produces these errors:

also the {call_hook name="citedby"} in templates/article/article.tpl doesn't show any output, it terminates the template rendering (nothing is shown on the page from the position of the hook down).

Do you know if the plugin is incompatible with the new OJS version? But if I remember correctly, the same errors were produced also in OJS 2.3.6.

Kind regards,
Ales
