(I've mostly lapsed in maintenance of this project. The Python parts work, at least for the purposes of Daylight, but aren't updated to work with citeproc-py past 3.0.0. On the Perl side, test_ris_input.pl passes, but test_citematic.pl, which tries to actually get stuff from the Internet, fails.)

Citematic::Get uses Google Scholar, the Library of Congress's online catalog, CrossRef, and a variety of other websites (including PubMed, APA PsycNET, JSTOR, and ERIC) to get bibliographic data for search terms, completely avoiding paywalls. It returns at most one result per invocation, so if you aren't looking for a specific item, you're probably better off with web interfaces. It does elaborate work to get exactly correct APA style (by both cleaning the input bibliographic data and tweaking the output references-section entries), and has test cases for over 100 items, including journal articles, book chapters, and entire books.

The actual output of the get function provided by Citematic::Get is a nested data structure of Citation Style Language 1.0 variables (as specified in the input data schema, except that no id is provided). The included Python module "quickbib" uses citeproc-py to generate bibliographies from CSL data using any CSL style you like (but with special support for APA style, because neither CSL nor citeproc-py can get it 100% right with only their built-in features). Citematic::QuickBib provides a Perl interface to quickbib, and the Perl script cite provides a handy command-line interface to the whole mess. Finally, Citematic::Get also has a function digest_ris for parsing RIS, and the Python module "citematic_coins" has a function coins to generate ContextObjects in Spans (COinS) from CSL input data.

You can put bounds on the year, rather than searching for an exact year, by using syntax like this (not supported for Library of Congress searches):

• 1990.. — Items published in 1990 or later
• ..2000 — Items published in 2000 or earlier
• 1990..2000 — Items published between 1990 and 2000 inclusive

See cite --help for a description of command-line options. See Perl/test_citematic.pm for more examples of what Citematic::Get can find and Python/test_apa.py for more examples of what quickbib can format.

Installation

1. Ensure you have the following Perl modules. You can install modules with sudo cpan install WWW::Mechanize or sudo cpanm WWW::Mechanize (using cpanminus) or your package manager.
   • Citematic::Get requires: Business::ISBN File::Slurp HTML::Entities HTTP::Cookies::Mozilla HTTP::Request::Common JSON List::Util LWP::Simple Text::Aspell URI URI::Escape XML::Simple parent
   • Citematic::QuickBib requires: IPC::Run JSON
   • cite requires: File::Slurp Getopt::Long::Descriptive
2. You'll also need Firefox or another Mozilla browser, because Citematic uses Mozilla cookies to pass robot checks.
3. Install Get.pm, QuickBib.pm, and COinS.pm themselves, as by putting them in /etc/perl/Citematic.
4. Ensure you have Python 3, then get and install (as by putting it in /usr/lib/python3/dist-packages) citeproc-py and its own dependencies, as well as the files quickbib.py and citematic_coins.py provided by Citematic. The version of citeproc-py with which this version of Citematic has been tested is 0.3.0.
5. Download apa.csl (and, if you'll be running quickbib's one test for it, mla.csl) and set the environment variable APA_CSL_PATH to where you put it (ditto MLA_CSL_PATH).
6. Copy the example configuration file to $HOME/.citematic and edit it. You'll need to register for CrossRef before you can use your email address for crossref_email.

Running the tests

For quickbib, enter the Python directory and say py.test. This requires pytest.

For Citematic::Get, say perl test_citematic.pl and perl test_ris_input.pl. This requires Test::More.

citematic_coins has no real test suite, but see coins_demo.py.

Caveats

The bibliographic data that exists is imperfect and only so much can be done automatically. For example, when the title of an article is provided in title case, we need to convert it to sentence case for APA style, but it's hard to tell whether some words should capitalized or uncapitalized (e.g., "China" is the word for the country but "china" is a synonym for "ceramic"). And in writing the test suite, I've found that bibliographic data contains a non insignificant number of outright errors. I've implemented some corrections for specific databases and specific journals, but not specific articles.

Every query is cached, but the cache never times out. You'll need to delete the cache file or edit it by hand in order to see any updates to the databases.

Why did you call it "Sittymatic"?

It's pronounced "CITE-uh", you numskull.
