The apacite package (for LaTeX and BibTeX) attempts to capture the requirements of the American Psychological Association concerning citations and reference list as closely as possible. In addition, it provides a large number of options and other possibilities for customization, so that a wide range of citation styles and reference list styles can be handled. Furthermore, it also provides the possibility of automatically generating an author index.
The index package (index.sty, available from CTAN; search for index.sty or index.dtx) must be available in a place where TeX can find it. This is necessary for the apacite package if an author index is requested, and this is done in the document apacite.tex.
The url package (url.sty) must be available in a place where TeX can find it. This is not necessary for the apacite package itself, but for the test examples from the APA manual that are used in the document apacite.tex.
The documentation of the apacite package is in the file apacite.pdf. This file can also be generated by processing the file apacite.tex, which in this way acts as an extensive test of the package. To get the references, the author index, and the table of contents of apacite.tex right, the following list of commands must be executed:
latex apacite bibtex apacite latex apacite latex apacite latex apacite makeindex -o apacite.and apacite.adx latex apacite latex apacite makeindex -o apacite.and apacite.adx latex apacite
So 10 runs are necessary in order to get everything OK.
