Practices in Code Discoverability: Astrophysics Source Code Library

TL;DR

The paper describes the Astrophysics Source Code Library (ASCL), a comprehensive, actively curated repository of astrophysical source codes linked to peer-reviewed research, enhancing code discoverability and reproducibility.

Contribution

It introduces an active approach to collecting astrophysics source codes by curating entries from peer-reviewed papers without requiring direct author submissions.

Findings

Over 340 codes cataloged, growing at 19 codes per month

Codes are used in peer-reviewed publications and freely accessible

The library improves code discoverability and research reproducibility

Abstract

Here we describe the Astrophysics Source Code Library (ASCL), which takes an active approach to sharing astrophysical source code. ASCL's editor seeks out both new and old peer-reviewed papers that describe methods or experiments that involve the development or use of source code, and adds entries for the found codes to the library. This approach ensures that source codes are added without requiring authors to actively submit them, resulting in a comprehensive listing that covers a significant number of the astrophysics source codes used in peer-reviewed studies. The ASCL now has over 340 codes in it and continues to grow. In 2011, the ASCL (http://ascl.net) has on average added 19 new codes per month. An advisory committee has been established to provide input and guide the development and expansion of the new site, and a marketing plan has been developed and is being executed. All ASCL source codes have been used to generate results published in or submitted to a refereed journal and are freely available either via a download site or from an identified source. This paper provides the history and description of the ASCL. It lists the requirements for including codes, examines the benefits of the ASCL, and outlines some of its future plans.
