Thanks, I'd not thought of the crossref api for this. I use the API pretty heavily for other things though, really good work!

Just noticed this part of the response:

    "affiliation": [],

How well filled in is that? I find it's currently a really poorly provided thing on many sites (although there are metatags, they're often wrong).

> When a PDF has Crossref CrossMark, the DOI is embedded in the metadata (I can't say how but I can find out)

That's likely to come in really useful, thanks.
