IMPORTANT NOTE: This is the package formerly known as biblatex-chicago-notes-df. It is designed for use with the latest version (3.4) of biblatex. The package still contains both the 15th- and 16th-edition Chicago style files, though I have marked the 15th-edition styles as "obsolete" and have moved them into a separate subdirectory, and I am concentrating all of 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 styles, and very strongly advised for the notes & bibliography style (version 2.5 is designed for use with the latest biblatex). README (version 1.0rc1, 2016-06-07): Biblatex-chicago contains three biblatex styles implementing the specifications of the Chicago Manual of Style, 16th edition. The "notes & bibliography" style was formerly available in the package biblatex-chicago-notes-df, and is intended primarily for writers in the humanities. The "author-date" style, generally favored by writers in the sciences and social sciences, comes in two flavors. 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 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 choose one of these three up-to-date styles, which should now cater to nearly all needs. The 15th-edition styles have received no fixes or updates, and won't compile with the latest biblatex. If you absolutely must continue using them, you'll need to specify "notes15" or "authordate15" in the options when loading biblatex-chicago, and downgrade biblatex itself, perhaps to version 2.9a. 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, which contains 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 Quickstart section in that same file, then read either cms-notes-intro.pdf or cms-dates-intro.pdf, each of which are fully cross-referenced and contain links to the complete reference guide to both styles in sections 4 or 5 of biblatex-chicago.pdf. 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) or my system (cms-notes-sample.pdf, cms-dates-sample.pdf, cms-trad-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. 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-dates-common.cbx, 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, cms-nynorsk.lbx, and cms-swedish.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 <TEXMFLOCAL>/tex/latex/biblatex-contrib/biblatex-chicago, where <TEXMFLOCAL> 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 seventeen files biblatex-chicago.tex, biblatex-chicago.pdf, cms-notes-intro.tex, cms-notes-intro.pdf, cms-dates-intro.tex, cms-dates-intro.pdf, cms-trad-appendix.tex, cms-trad-appendix.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, notes-test.bib, dates-test.bib, and cmsdocs.sty can all be found in the doc/ directory in the package archive, the last 15 in the examples/ subdirectory. You can place all of this in <TEXMFLOCAL>/doc/latex/biblatex-contrib/biblatex-chicago. - The ten files chicago-notes15.bbx, chicago-notes15.cbx, chicago-authordate15.bbx, chicago-authordate15.cbx, biblatex-chicago15.tex, biblatex-chicago15.pdf, cms15-notes-sample.tex, cms15-dates-sample.tex, cms15-notes-sample.pdf, and cms15-dates.sample.pdf can all be found in the obsolete/ subdirectory in the package archive. You can place that directory in <TEXMFLOCAL>/tex/latex/biblatex-contrib/biblatex-chicago. Changelog: See the RELEASE file, and also the end of biblatex-chicago.pdf.
