biblatex seems to be not compatible with RevTeX. As RevTeX automatically loads natbib, I load biblatex with the option natbib=true, but still LaTeX compiler complains that lot of commands are already defined. I make them undefined as follows:


but still obtain various errors such as

! Package biblatex Error: Incompatible package 'natbib'.

See the biblatex package documentation for explanation.
Type  H <return>  for immediate help.

I've checked that natbib compatibility mode is switched on:

Package biblatex Info: Trying to load natbib compatibility...
Package biblatex Info: ... file 'blx-natbib.def' found.
 ("C:\Program Files (x86)\MiKTeX 2.9\tex\latex\biblatex\blx-natbib.def"
File: blx-natbib.def 2011/02/13 v1.2a biblatex natbib compatibility

So, it looks as if that trouble comes from RevTeX. I tried both RevTeX4 and more recent RevTeX4-1. No difference.

  • Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they are marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it). Error messages with file paths should be set using <pre> ... </pre> HTML tags to avoid highlighting them as TeX macros. – Martin Scharrer Feb 25 '11 at 14:41

    The biblatex manual states that natbib is incompatible with biblatex. The natbib option is unrelated to the package (it emulates it, but doesn't make it compatible). – Philipp Feb 25 '11 at 17:21

    Does anyone have any ideas on how difficult implementing a fork of RevTeX 4.1 that would be compatible with biblatex would be? I'd be prepared to put a bounty on it. As Igor mentions in the comment in the answer by Lockstep, this class dominates physics. – qubyte Nov 24 '11 at 4:13

Since biblatex "reimplements the bibliographic facilities of LaTeX from the ground up, [it] naturally conflicts with all packages modifying the same facilities" (manual, section 1.5.4). Specifically, biblatex is incompatible with natbib. biblatex' natbib option only provides aliases for natbib's citation commands.

From a look into the manual of RevTeX 4.1, natbib is a required package, and multiple custom options and commands are defined on top of natbib. So no, I'm afraid biblatex is incompatible with RevTeX.
