Can I insert multiple bibliographies in a single document?
Paperpile does not currently support complex / multiple bibliographies. We understand there are several use cases for this; some advice below.
For multiple chapters / sections
Different sections can be divided in separate documents (either while writing, or at the end), where each bibliography can be formatted accordingly and then pasted back to the final manuscript.
For CVs and lists without in-text citations
The best way to go here would be grouping references under a specific folder or label in the library, then generating plain-text formatted bibliographies (select references and hit Ctrl+C) to be pasted in any document.
