+Bibliography Processors
+\end_layout
+
+\begin_layout Standard
+To generate the bibliography from a database, \SpecialChar LyX
+ uses a bibliography processor,
+ that is an external program that reads the database, sorts the citations
+ and processes the data in a way it can be included in the document.
+ The classic program is called Bib\SpecialChar TeX
+.
+ It has the advantage that it is very mature and widespread, but the disadvantag
+e that it has severe limitations, due to its age.
+\end_layout
+
+\begin_layout Standard
+Meanwhile, some alternatives have been developed that address some of these
+ limitations.
+ LyX natively supports some of them and lets you select a custom processor.
+ You can do this on a general level in
+\family sans
+Tools\SpecialChar menuseparator
+Preferences\SpecialChar menuseparator
+Output\SpecialChar menuseparator
+LaTeX
+\family default
+ or for individual documents in
+\family sans
+Document\SpecialChar menuseparator
+Settings\SpecialChar menuseparator
+Bibliography
+\family default
+.
+ The following variants are available by default:
+\end_layout
+

+\series bold
+biber
+\series default

+
+\series bold

+\end_layout

+\begin_layout Description
+bibtex the standard; does not allow special characters in bibliography entries
+ that are not possible to encode in a 7-bit encoding, limited memory, works

+ bibliographies due to the limited memory.
+\end_layout

+\begin_layout Description
+bibtex8 allows all characters that are possible to encode in an 8-bit encoding

+\family sans

+\family sans

+ for Bib\SpecialChar TeX
+-based bibliography styles).
+ This should suit most needs.
+\end_layout

+\begin_layout Standard
+In Japanese documents, a specific processor is used.
+ By default this is pBib\SpecialChar TeX
+ (in \SpecialChar LyX
+
