Enter Date of publication unknown

felix.peter
Hello,

for my university I have to write my own style. My problem is now that I would like the citation to write "publication date unknown" when I do not have any date (year9 information entered in Zotero.

It would be great if you could help me out with this.

Cheers.

    you can test for
    <if variable="issued" match="none">
    and then write something like
    <text value="publication date unknown"/>

    Thanks for the quick response. is there also a way how I can do that in the visual csl editor?
  • adamsmith
    Generally yes, anything that's possible in CSL can be done in the visual editor. The basic idea is that you'll need to add nodes by clicking on the plus sign at the top left - first a choose node, then an if node with the condition above, then the text node. It's going to be a little cumbersome, but shouldn't be terribly hard.

    Thanks a lot for this. I tried before but it didn't work but because you mentioned I should use the variable issued it works just fine now :)
