Re: Parsing error ? with addref

Thanks Markus and Rich,

The single letter keywords are partially a legacy data issue and
partially disciplinary. In manuscript and textual studies some
manuscripts are known by 1 or 2 letter sigla: Corpus Christi College
Manuscript 41 is known as b1 to most Anglo-Saxonists. Also you could
have an article about the Anglo-Saxon word æ. In previous databases, we
keyworded things like this because searching all fields was more
difficult. My plan in refdb is to rationalise things.

The multiple keywords is also a legacy of some script a student ran
through once.

I'd read the data mangling section but missed the significance of what
refdb was doing. I'll turn it off until the data is in better shape, I
think!
