I want to use a bibliography style that not installed with texlive. How could I install new bibliography style on texlive (windows 7)?
If you put the
bst file for the new style into the same directory as your tex file then
(bib)TeX will find it. Alternatively, you put the system directory containing the other bst files (for me this is
.../texlive/2013/texmf-dist/bibtex/bst), but this will depend on your distribution.
Under UNIX there is also a
BIBTEX environment variable, with similar syntax to
TEXINPUTS, but I don't know the equivalent under windows. Setting thi allows you to put these files "anywhere" and still have bibtex and friends find the style.
After This, you must refresh the database of your texlive to where find everything. If you don't refresh the database the tex engine will not find this and other new files in the tex directory.
You can update your database by typing
texhash in the Tex Live command-line.
