Zotero needs a preprint category
In many subjects, a lot of scholarly work appears, and gets cited as a preprint.
The current solution for zotero is to classify the reference as a Journal Article, with the Publication field being the identifier.
This is a bad solution, because a pre-print archive is not a journal, and a preprint is not a journal article.
The bibtex entry recommended by arXiv for example, asks for preprint items to be ```@misc``` instead of ```@article```, and it should not have a ```journal``` field, but a ```eprinttype``` instead. This matters not just for a typographical aspect, but also for the automation aspects.
