\maketitle

\begin{abstract}
As part of its scholarly data efforts, the Internet Archive releases a citation
graph dataset derived from scholarly publications and additional data sources. It is
composed of data gathered by the \href{https://fatcat.wiki}{fatcat cataloging project} and related
web-scale crawls targeting primary and secondary scholarly outputs. In
addition, relations are worked out between scholarly publications, web pages
and their archived copies, books from the Open Library project as well as
Wikipedia articles.

As of version "20210810", the graph consists of over X nodes
and over Y edges. We release this dataset under a Z open license under the
collection at \href{https://archive.org/details/citation\_graph}{https://archive.org/details/citation\_graph}, as well as all code
used for derivation under an MIT license.

\section{Introduction}

The Internet Archive releases a first version of a citation graph dataset
derived from a raw corpus of about 2.5B references gathered from metadata and
from data obtained by PDF extraction tools such as GROBID\citep{lopez2009grobid}.
The goal of this report is to describe briefly the current contents and the
derivation of the Internet Archive Scholar Citation Graph Dataset (IASCG). We expect
this dataset to be iterated upon, with changes both in content and processing.

Modern citation indexes can be traced back to the early computing age, when
projects like the Science Citation Index (1955)\citep{garfield2007evolution}
were first devised, living on in existing commercial knowledge bases today.
Open alternatives were started such as the Open Citations Corpus (OCC) in 2010
- the first version of which contained 6,325,178 individual
references\citep{shotton2013publishing}. Other notable sources from that time
include CiteSeerX\citep{wu2019citeseerx} and CitEc\citep{CitEc}.
