Enhancements to the Astronomy Source Code Library (ASCL)

The Astronomy Source Code Library (ASCL) is a rapidly growing, free online registry for astronomical source codes that have been used in research that have appeared in, or been submitted to, peer-reviewed publication. There are now over 900 codes indexed by the ASCL,  and this reflects a growing understanding in the community of the need to expose code in verifying science results.


The ASCL has been active in the community, in organizing workshops and panels on code sharing. It is indexed by the SAO/NASA Astrophysics Data System (ADS) and is citable by using the unique ascl ID assigned to each code. The ascl ID can be used to link to the code entry by prefacing the number with ascl.net (i.e.ascl.net/1201.001).

In response to its recent growth,  the Library has made a number of enhancements to its infrastructure and interfaces to improve services for users.  For example, it now uses a MySQL database for code records, and WordPress and phpbb discussion forums are fully integrated into the site.

The web page now offers a simpler submissions form; shows the the ten newest codes on the home page; provides much improved browsing, with abstract and compact views, and ordering of codes by alpha, reverse alpha, and newest or oldest additions; offers a one-click author search that can be expanded; as well as bibcode and discussion thread links in each record.

Section of the new browse page:


Future capabilities will include a dashboard for statistics and information,; a “See also” field for related codes; and Previous and Next links for paging through code entries.

The Astrophysics Source Code Library (ASCL) was founded in 1999 by Robert Nemiroff and John Wallin. The Editor is Alice Allen. Disclosure: I am a member of the advisory board
