Thanks Adam.

I'll install the beta version and hope to God it doesn't do anything nasty to my work a week before deadline :)

Actually, the Citation Style Language should allow for this (although the solution is a bit more complex). If you enter "Facebook" as the "Website Title" of your "Web Page" Zotero item, you could modify the citation style's substitution logic: when an item doesn't have any authors, the value of the "container-title" field can be substituted (this CSL field maps to Zotero's "Website Title" field).

Assuming you're using the Harvard1 style that ships with Zotero, you could change:

<macro name="author-short">
<names variable="author">
<name form="short" and="symbol" delimiter=", " delimiter-precedes-last="never" initialize-with=". "/>
<substitute>
<names variable="editor"/>
<names variable="translator"/>
<text macro="anon"/>
</substitute>
</names>
</macro>
into
<macro name="author-short">
<names variable="author">
<name form="short" and="symbol" delimiter=", " delimiter-precedes-last="never" initialize-with=". "/>
<substitute>
<names variable="editor"/>
<names variable="translator"/>
<text variable="container-title" font-style="italic"/>
<text macro="anon"/>
</substitute>
</names>
</macro>

The bibliography uses a different macro, for which you can add the same substitution rule. In the "author" macro, change
<substitute>
<names variable="editor"/>
<text macro="anon"/>
</substitute>
into
<substitute>
<names variable="editor"/>
<text variable="container-title" font-style="italic"/>
<text macro="anon"/>
</substitute>

Just going through and amending my library now to place organisational website authors into the Webpage Title field.

I've encountered a small problem that I didn't anticipate.

In my thesis, I have referenced newspaper articles written by a news organisation which appear on a newspaper website.

For instance, an article written by AP that appears on nytimes.com.

Originally, I would put "Author" as "AP" and "Website Title" as "New York Times". Now that "AP" has shifted to "Website Title", "New York Times" is homeless. I've tried to put it in one of the other boxes (Short Title, Language, etc.) but Zotero only seems to source website bibliographical details from the Title, Author, Website title, Date, URL and Accessed fields.

Is there any way to instruct Zotero to grab bibliographic info from another box - say, "Website Type" - which I can then put the website name in?

Thanks
Hayden

Thanks.

If I list it as a newspaper type (which is what they are currently) I'm back to my original problem - no italics for the organisation in question.

@hayjay: At the risk of some criticism from colleagues in CSL for jumping the gun, I'll chime in here with an alternative possibility, drawn from ongoing CSL development. If you have an instance of Zotero 2.1 installed, you might give this style a try [click on the "raw" link to download the file, then drag the file into the Firefox window to install]]. It should apply italics to institutional authors (authors entered with single-field mode in Zotero), for all item types.

While this style is not valid against the current CSL 1.0 schema, it has a couple of advantages, in that sorting and presentation will (or at least should) work normally in the bibliography, and items with mixed authorship (i.e. an individual author sharing credit with their affilliated institution) will format correctly, with the institutional author set as an author, and in italics.

I should stress (as others no doubt will) that the CSL code in the style does not carry the CSL imprimatur, and as such is unsupported, and is subject to change without notice. I offer it up because if it works, it might simplify your prep for submission; but if you try it and run into problems, you should go with the good advice already given by Rintze and noksagt.

A doc describing the CSL code is available here, if you're interested (note that the link is to a Google Groups page, which will disappear when Google eliminates that part of the service early next year).

@hayjay: What Bruce said. Reading more carefully, I see that my institutional authors suggestion is at cross purposes to (at least the better part of) your use case. Interested to hear what works for you in the end.

Thanks everyone for your input - certainly adds complexity to the situation! I'll investigate further in the coming days and settle with an appropriate solution.
Thanks again.

no, not at the moment - I think that in the 2.1 version using mark-up (such as <i> </i> etc.) in the prefix suffix field might do that for you, but someone would have to confirm.
