# Global bibliography ignoring references after

I am using @moewe's answer in: Bibliography per chapter and a global bibliography in alphabetic order

I would like for the references used AFTER the global bibliography to not be included in it. Here's a modified MWE from the link above:

As you can see, references that only appear in the appendix (after the Global References) are also included in the Global References. I would like them to be disregarded (yet, have a local References section after the Appendix for whatever was cited within).

• Haven't tested it, because I should get some sleep now, but have you tried adding \newrefsection before \appendix (or \chapter{Appendix 1})? Or are we only talking about the pageref? – moewe Jun 24 at 21:05
• @moewe Just tried it, didn't work :/. The work around I'm using is to have a separate bib file with the refs in appendices and a particular keyword and assigning those to a category appendix while using notcategory=appendix when printing the global references – ralk912 Jun 24 at 21:13

The code sets the category cited at every cite key. You can make this category conditional on if you are in the appendix or not. In the code below a boolean \ifapx is created that is initially false, and (manually) set to true in the appendix. The \AtEveryCitekey command uses this boolean to add the cited category only in the main text.

Code:

• Ah I did think of using an if statement (and notice the problem might have been with that AtEveryCitekey, but I couldn't find how to declare it ! – ralk912 Jun 24 at 21:14
• It's a bit of a workaround, there probably is a solution from within biblatex that properly separates the reference sections - but this was quick and it worked... – Marijn Jun 24 at 21:18
