This is why these jobs are often outsourced to freelance writers in order to free up "in-house" resources and I have to say that I do sometimes quite enjoy this kind of work. You can just sit, rest the right hemisphere and get on with it, step-by-step. The sleuthing nature of it also appeals to me, there is such a sense of accomplishment when you can find a reference from only an author name and year, although this is supremely rare!
It may not be glamorous or win awards, but there exists a time and place where the drudge becomes a joy!
