I have a document with multiple bibliographies (generated with biblatex and biber). I am wondering if it is possible to suppress the generation of a letter after the year (extrayear) for only one if the bibliographies.
From a previous question, I learned that the label can be suppressed through various tweaks in the preamble, but that affects all bibliographies, of course.
From the biblatex manual (p. 188 in version 2.0) , I understand that I can deactivate the label on a per-entrytype basis, but that will not do in my case. The manual also states that customization of labelyear is not possible on a per-item/per-entry basis (Appendix D).
So my question is whether there is a workaround to suppress the label anyway, for example on a per bibliography basis or a per keyword basis.
I am thinking, for example, of a combination of
\AtEveryBibitem and some if/then loop that filters for keywords. But I am unfortunately unable to program such a thing...
