In words:

For 72% of DOAJ documents, we have recorded at least one reference to a target
and for 56% of the DOAJ documents, we have record at least one citation
pointing to it.

About 7% of the citation we find are intra-DOAJ, that is both the citing and
the cited article is in DOAJ.

## Glossary

### Edge

An edge records a link between a source metadata document and a target metadata document
(from the fatcat catalog) - where a source cites a target.

In the [catalog](https://fatcat.wiki) we also display unmatched references, that is reference
information from a source, that has not been matched to a target yet. These are
called "unmatched refs", sometimes.

### Fatcat.wiki

The catalog underlying [Internet Archive Scholar](https://scholar.archive.org).

### Internet Archive Scholar

A academic [search engine](https://scholar.archive.org) over 100M metadata and over 30M fulltext documents, updated in
near real-time as new metadata and fulltext document become available in the fatcat (catalog).

### Internet Archive Scholar Citation Graph

A citation graph derived from scholarly metadata and fulltext documents curated
at the Internet Archive. Version 1 has been released in 10/2021. Futher
information can be found here:
