Citematic::Get uses EBSCOhost, IDEAS (i.e., RePEc), and CrossRef to get bibliographic data for search terms. In the case of EBSCOhost, it also tries to get full-text URLs. It returns at most one result per invocation, so if you aren't looking for a specific item, you're probably better off with the web interfaces.
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). 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::COinS has a function
coins to generate ContextObjects in Spans (COinS) from CSL input data.

- Ensure you have the following Perl modules. You can install modules with
sudo cpan install WWW::Mechanizeor
sudo cpanm WWW::Mechanize(using cpanminus) or your package manager.
- Citematic::Get requires: File::Slurp HTML::Entities HTTP::Cookies JSON LWP::Simple List::Util Text::Aspell URI::Escape WWW::Mechanize XML::Simple parent
- Citematic::QuickBib requires: IPC::Run JSON
- Citematic::COinS requires: HTML::Entities URI::Escape
citerequires: File::Slurp Getopt::Long::Descriptive
- 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.
- Download apa.csl (and, if you'll be running quickbib's one test for it, mla.csl) and set the environment variable
APA_CSL_PATHto where you put it (ditto
- Copy the example configuration file to
$HOME/.citematicand edit it. Registering for CrossRef is easy. Getting access to EBSCOhost is harder. There's a good chance that your school (if you're using Citematic, you must be a student or an academic, right? right?) or your local library has an institutional subscription that you can use from home. You may be able to log in with a single HTTP
POST(the Firefox extension Tamper Data is helpful for figuring out how), in which case editing
ebsco_loginwill be particularly easy. And if your IP address is already authenticated, then you don't need to log in at all, and you can set
ebsco_loginto a no-op like
1. (Perl programmers note that
$_refers to a WWW::Mechanize object in this context.)
Running the tests
For quickbib, enter the Python directory and say
py.test. This requires pytest.
For Citematic::Get, say
perl test_citematic.pl. This requires Test::More.
If you look at the code of Citematic::Get, you'll see that a great many cases need to be covered in order to parse all the idiosyncratic record formats. You'd hope that all that data would be systematically structured, huh? It isn't really, hence regexes. I've done a pretty good job (if I do say so myself) of covering psychology articles (particularly those represented in PsycINFO and PsycARTICLES), but more regexes will no doubt be needed if you plunge further into the depths of, say, MEDLINE. And while I implemented support for IDEAS so I can get economics articles, fields like mathematics and chemistry will probably require more databases. In short, I wrote this program for my own use, so I took pains to support the sort of articles I read (in experimental social psychology and JDM), but the further your interests are from mine, the more work you'd have to do to make Citematic::Get useful. Patches are more than welcome; I would love for Citematic to be as well-rounded in scraping as it is in formatting.
Another thing: every query is cached, but the cache never times out. You'll need to delete the cache file or edit it by hand (or in the case of EBSCO, use the
-b option to
cite) in order to see any updates to the databases.
Will I get in trouble for using this program?
There may be some restrictions on what you can do with the data you get, which apply just the same as if you'd used the web interface (e.g., EBSCO's terms say something about "non-commercial use"), but given that fair-use laws apply, I doubt you'll have any problems.
And, of course, since this is mostly done with web scraping, server-side changes could suddenly render Citematic::Get inoperable.
Why didn't you use Z39.50?
I couldn't get it to work.
Why did you call it "Sittymatic"?
It's pronounced "CITE-uh", you numskull.
