IMPORTANT NOTE: This is the package formerly known as biblatex-chicago-notes-df. It has now been upgraded to work with version 2.5 of biblatex. It contains both the 15th- and 16th-edition Chicago style files, though I am now marking the 15th-edition styles as "deprecated" and am concentrating my development time on the 16th edition. If you have used the package before, then you should be sure to consult the RELEASE file to find out what alterations you may need to make to your .bib files and document preambles to bring them up to date. Most particularly please note that Biber is now required for the author-date style (version 1.5 if you are using the latest biblatex, 0.9.8 or 0.9.9 if you are still using biblatex 1.7). README (version 0.9.9c, 2013-03-15): Biblatex-chicago contains five biblatex styles implementing the specifications of the Chicago Manual of Style in both its 15th and 16th editions. The "notes & bibliography" style was formerly available in the package biblatex-chicago-notes-df, and is intended primarily for writers in the humanities. I would encourage all users of the 15th edition style to upgrade to the 16th: it contains many new features, and the changes involved, being largely incremental, generally won't require major alterations to your .bib files. The "author-date" style, generally favored by writers in the sciences and social sciences, presents a somewhat different case. The 16th edition of the Manual has brought the presentation of sources in this style much more into line with the notes & bibliography specification, especially regarding the formatting of titles. If you still require titles to be capitalized sentence style, and article titles, for example, not to be enclosed in quotation marks, then you may now use the new, traditional author-date style ("authordate-trad"), which provides these features while in all other respects following the 16th-edition specifications. I encourage all users to upgrade to one of these three up-to-date styles, which should now cater to nearly all needs. If you wish to continue using the 15th-edition files, you'll need to specify "notes15" or "authordate15" in the options when loading biblatex-chicago. This is a beta release, but its feature set is already fairly extensive. If you have used the package before you may, after perusing the RELEASE file, want to look at the changelog at the end of biblatex-chicago.pdf (and/or biblatex-chicago15.pdf), which contain cross-references to more detailed explanations about how this update will affect parts of your .bib file. If you are just getting started, the best way to learn the system is to read the documentation in those same pdf files, which contain both a Quickstart section and a complete reference guide to both notes & bibliography and author-date styles (sections 4 and 5). The package also contains annotated .bib files (notes-test.bib and dates-test.bib) which each offer over 100 entries demonstrating how to present a wide range of sources, nearly all of them taken from the Chicago Manual of Style itself, so that you can compare the output of your system (cms-notes-sample.tex, cms-dates-sample.tex, cms-trad-sample.tex, cms15-notes-sample.tex, cms15-dates-sample.tex) or my system (cms-notes-sample.pdf, cms-dates-sample.pdf, cms-trad-sample.pdf, cms15-notes-sample.pdf, cms15-dates-sample.pdf) with the actual examples in the Manual. I have, wherever possible, attempted to maintain backward compatibility with the standard biblatex styles, but there are a significant number of situations where I have been unable to do so, which means that switching among various styles while using the same bibliography database will not be as simple and painless as it could be. If you can see ways better to preserve this compatibility, or indeed to improve the package in any way whatsoever, please let me know, or better yet, send a patch. As the 16th edition styles are relatively new, now is the time to suggest changes in field or entry-type usage there, before questions of backward compatibility become more pressing. If the styles don't behave as you expect or if you discover a bug, I'd be very happy to hear about it, but do please read biblatex-chicago.pdf first, as you may find that your question has already been answered there. If you do find a bug, please send me the .bib entry, your LaTeX preamble, and your output .log, so that I can try to reproduce it here. My email address is at the head of biblatex-chicago.pdf. Installation: With the recent proliferation of files, I have adopted the directory structure found in biblatex.zip, so if you want to place these files in your TeX directory tree instead of in your working directory, I recommend the following, which should be familiar from the main biblatex package: - The twenty-one files biblatex-chicago.sty, chicago-notes.cbx, chicago-notes.bbx, chicago-authordate.cbx, chicago-authordate.bbx, chicago-authordate-trad.cbx, chicago-authordate-trad.bbx, chicago-notes15.cbx, chicago-notes15.bbx, chicago-authordate15.cbx, chicago-authordate15.bbx, cms-american.lbx, cms-british.lbx, cms-finnish.lbx, cms-french.lbx, cms-german.lbx, cms-icelandic.lbx, cms-ngerman.lbx, cms-norsk.lbx, cms-norwegian.lbx, and cms-nynorsk.lbx are located in the latex/ subdirectory, itself further subdivided into bbx/, cbx/, and lbx/. The entire contents of this latex/ directory, including its subdirectories, can go in /tex/latex/biblatex-contrib/biblatex-chicago, where is the root of your local TeX installation -- for example, and depending on your system, /usr/share/texmf-local, /usr/local/texmf, or C:\Local TeX Files\. You may need to create this directory first, and after copying the files there please remember to update your TeX file name database so that TeX can find them. - The sixteen files biblatex-chicago.tex, biblatex-chicago.pdf, biblatex-chicago15.tex, biblatex-chicago15.pdf cms-notes-sample.tex, cms-dates-sample.tex, cms-trad-sample.tex, cms-notes-sample.pdf, cms-dates.sample.pdf, cms-trad-sample.pdf, cms15-notes-sample.tex, cms15-dates-sample.tex, cms15-notes-sample.pdf, cms15-dates.sample.pdf, notes-test.bib, and dates-test.bib can all be found in the doc/ directory in the package archive, the last 10 in the examples/ subdirectory. You can place all of this in /doc/latex/biblatex-contrib/biblatex-chicago. Changelog: See the RELEASE file, and also the end of biblatex-chicago.pdf (or biblatex-chicago15.pdf).
