The main output of the OpenCitations Project is the creation of the Open Citations Corpus (OCC), an open repository of scholarly citation data made available under a Creative Commons public domain dedication, which provides in RDF accurate citation information (bibliographic references) harvested from the scholarly literature. These are described using the SPAR Ontologies according to the OCC metadata model, and are made freely available so that others may freely build upon, enhance and reuse them for any purpose, without restriction under copyright or database law.
The OCC is being continuously populated from the scholarly literature.

and the extensive FAQ section, which provides answers to over 300 common questions.
Site features
Improved navigation
When you scroll down a page, the top navigation bar remains visible at the top of your screen,
so the page name, breadcrumb trail, and other links are always available.
Pop-up index display
Documentation pages now have a 'Show page index' link in the navigation bar. Clicking this
opens a draggable, resizable window with an overview of the page you're reading.
Improved search
It's now even easier to find the page you need. For example, just type 'getopt long' into
the search box to be taken directly to the Getopt::Long documentation.
Recently viewed pages
The right-hand side panel shows the last 10 documentation pages you viewed. As with the
search engine, this feature still works if you're using an offline local copy of the site.
Improved syntax highlighting
As well as a better highlighting algorithm, code blocks now have line numbers to make
it easier to see line breaks.
Module index links
View the module indexes with a single click from the left-hand side panel.
Downloads
The complete documentation set is available to download for offline use.
Full version (contains HTML and PDF files) - perldoc.tar.gz
As well as the documentation pages, the perldoc search engine is also included in the above downloads.
No installation is required, just unpack the archive and open the index.html file in your web browser.
