Kevin,
I haven't tried JabRef, but Zotero does export my web pages as "misc" in a format that LyX understands anyway. However, Zotero doesn't export the "lastchecked" field, I believe since it's not "standard" bibtex.
Ah, I never tried using the Zotero to bibtex direct route, as I couldn't get Jabref to import the Zotero exported bibtex file.
I might rethink this

Thanks, I will have a look at this. Graham
