List of differences:
Author separation with & instead of and (in text citation as well as bibliography)
First name abbr. of subsequent Authors after family name not before
Bokk title italic
Journal name italic
A blank after the colon for separating volume and pages
"In: " instead of "in" for book chapters
"pp." instead of "Pages"
also Book titles in Book chapter type in italic
Editors must be cited

Bibliography is always printed in standard OpenOffice style, can you stop this?
Journal Abbreviation is JVS

Citations in the text: Use forms such as: Smith (2005) or (Smith 2005) or Smith et al. (2005) or (Smith 2005 a, b; Jones 2006).
References section: Use the formats below. Journal names; always give the full name.

Thanks a lot.

I think I mostly got it:
go here:
http://gist.github.com/273967
then download the style, using the "Raw" link on the top right.
Install by dragging the downloaded file into an open Firefox Window.
Please report back.

Not sure if there is a better way to amend the gist, but this should address the spacing issue:

Interested in styles creation.
with reference to a post by adamsmith, I need to understand the following terms used.
For example, what do the following syntax mean

<choose>
<if type="book chapter article-journal" match="none">
<date variable="issued">
<date-part prefix=", " name="month"/>
<date-part prefix=" " name="day"/>
</date>
</if>
</choose>
</group>
</if>
<else>
<text prefix=" (" term="no date" suffix=")."/>
</else>
</choose>
</macro>

<macro name="edition">
<choose>
<if type="book chapter" match="any">
<choose>
<if is-numeric="edition">
<number variable="edition" form="ordinal" prefix=", "/>
<text term="edition" form="short" prefix=" " suffix="."/>
</if>
<else>
<text variable="edition" suffix="."/>
</else>
</choose>
</if>
</choose>
</macro>

Particularly
<if type="book chapter article-journal" match="none">
and
<if type="book chapter" match="any">
Thanks and hope to read from you.

Sorry and thanks adamsmith for the reminder. I think I will open a new thread for more detailed explanation as it is still not clear.

is now correct - it also has the correct name, but it won't overwrite the old style, so you'll have to manually delete that one in the styles tab of the Zotero preferences (that's just for keeping things tidy, everything will still work with both styles installed).

Is this with Zotero 2.0 or Zotero 2.1?

(One of the reasons for asking is that Zotero 2.0 will disambiguate all names in references used in the document, even when they are masked by et al.)

I am using version 2.09 and yes, there was a small difference in the names (one with initials with and the other without trailing point).

Thanks both fbennett and ajlyon for answering my question.

Btw, is this feature, I guess you can call it a feature, going to change in version 2.1?

And thanks to adamsmith for creating this style of course!

Thanks for the explanation. In the case above, the difference was actually that the name was spelled out in the first reference and not in the second (when writing my previous comment I was looking at a wrong reference of Carrión). So even in version 2.1 that would result in the wrong result then.. good to know and you are right, easy to trouble-shot.

Unrelated to the issue above, but about the style: In the reference list, whenever an author has more than one initials, the first initial is followed by point+space instead of point only. So you have J. S. instead of J.S.

Should be fixed now. It was actually looking for an issue no. and if none was there it goes to DOI. I've relaxed this, so now it checks for either issue or volume and only if neither is present it assumes the article is online pre-publication and uses the DOI.
