The biblatex package allows you to write annotations to your bibliography as external files. I use those annotations to keep notes associated to the papers I read for my thesis.
Unfortunately, since the annotation of each bibliography entry has to be in a separate file, my TeX source directory gets quite cluttered. It would therefore be preferable if all annotations were in a separate directory but I cannot find a way to tell biblatex where to look for them. So my question is the following:
Is there any way to tell biblatex to look for the annotation files in a directory different from the current one?
