# Building a Citation Graph

* date: 2021-04-23
* status: implemented

## Problem and Goal

We want to generate a citation graph including bibliographic data from fatcat,
wikipedia, open library; additionally, we want to record web links as targets.

Citations indices and graphs can be traced back at least to the seminal paper
*Citation indexes for science* by Garfield, 1955 [1]. A anniversary paper [2]
published in 2005 already lists 17 services that include cited reference
search.

Roughly three broad problems need to be solved:

* A catalog (source) needs to be available, containing relatively clean
  metadata on scholarly communication documents.
* The reference data needs to be available, either in metadata directly or by
  extraction from documents.
* The datasets need to be compared.
