... and which journals have the most?
I had software citations on my mind all last week, as the 3rd Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3) was held last Monday and Tuesday in Boulder, CO, and I spent a good bit of my time there in the work group for Hacking the credit and citation ecosystem (making it work, or work better, for software). This made me curious as to which journals have citations to ASCL entries, and which have the most citations to ASCL entries. I was pretty sure I knew the answer to the latter, but it's always good to test what one knows. So I went looking, and this what I found...
These three journals and arXiv hold 84% of citations to ASCL entries:
Monthly Notices of the Royal Astronomical Society
The Astrophysical Journal
ArXiv e-prints
Astronomy and Astrophysics
Other publications with citations to the ASCL include:
| The Astronomical Journal Astronomy and Computing The Astrophysical Journal Supplement Series Computational Astrophysics and Cosmology Computer Physics Communications Galaxies Icarus Journal of Cosmology and Astro-Particle Physics Journal of Physics Conference Series |
Journal of Physics G Nuclear Physics The Messenger Physical Review C Physical Review D Physical Review Letters Physics Uspekhi Publications of the Astronomical Society of Japan Publications of the Astronomical Society of the Pacific Revista Mexicana de Astronomia y Astrofisica |
Proceedings, too, including:
| 18th European White Dwarf Workshop 19th European Workshop on White Dwarfs Astronomical Society of India Conference Series Asymmetrical Planetary Nebulae VI Conference |
EAS Publications Series IAU Symposium SF2A-2014: Proceedings of the Annual meeting of the French Society of Astronomy and Astrophysics Society of Photo-Optical Instrumentation Engineers (SPIE) Conference Series |
I appreciate ADS all over again for making it possible to compile this information so quickly.
Ten codes were added to the ASCL in August 2015:

From feedback we received about the "Ref" field, we've relabeled that field to lessen the confusion about the article link(s) in the Code Record. What had appeared is:
What now appears is:

We supply a link, too, to a page that explains what the Website, Appears in, and Bibcode fields are, and hope this makes things clearer.
If you have suggestions for the ASCL, please feel free to post them here or email editor@ascl.net. Thank you!

ASCL entries include a field called "Ref," for "refereed." As the ASCL indexes codes used in research, this field contains at least one link to a research article which describes a code or in which the code was used.

The information in the Ref field is used by ADS to link papers and the codes they use, making it easy for someone reading an article to find the code(s) used in that research. You can find these associations in the "Associated Articles" section of an ADS entry.
In the first image below, which is a screen clip from an ADS entry, the Source Software link brings up the ASCL entry for a code used in the article; in the second image, the Paper 1 link brings up a paper that used the code:

Some papers have several links in the Ref field:
These are papers we found while researching a code or were entered by a code author when submitting code to the ASCL. Associating article entries with entries for the codes used in those articles makes finding the software used in the research easier. And though software is increasingly cited (in a variety of ways), it isn't always, so using the Ref/Associated Articles links can help a code author demonstrate the impact of a particular software package.
I know the ASCL is missing many of these associations; ADS and the ASCL would like to improve this linkage. If you have ideas on how to do this, please post them here, or send them to editor@ascl.net. Thanks!
Ten codes were added to the ASCL in June 2015:
dmdd: Dark matter direct detection
EATCVB: Coronal heating rate approximations
fsclean: Faraday Synthesis CLEAN imager
multiband_LS: Multiband Lomb-Scargle Periodograms
PLATO Simulator: Realistic simulations of expected observations
pyKLIP: PSF Subtraction for Exoplanets and Disks
PyMC: Bayesian Stochastic Modelling in Python
REALMAF: Magnetic power spectra from Faraday rotation maps
SPRITE: Sparsity-based super-resolution algorithm
VAPID: Voigt Absorption-Profile [Interstellar] Dabbler
... maybe not like topsy, but steadily nonetheless. In looking at the ASCL's growth over the past year, I see that on June 15 of last year, ADS held 818 ASCL entries with 168 cumulative citations. 78 different codes had been cited by their ASCL ID, or 9.5% of codes in the ASCL.
Today, there are 1079 ASCL records in ADS with a total of 334 citations, nearly double last year, and the number of codes cited by ASCL ID has just more than doubled; that number now stands at 158, which is 14.6% of codes in the ASCL cited using the ASCL record.
So if my figuring is correct (no guarantees...), the ASCL has grown 32% in the past year (by 261 codes, from 818 to 1079), while codes in the ASCL cited by these entries is up 100%.
We are very interested in code citation, however that happens; we want software authors to gain exposure and credit for their work! A number of excellent ways to cite codes exist, and so long as codes do get cited, we don't care how. We track citations to ASCL entries because this is one way to determine whether the ASCL is being used; page views are another measure we employ.
And yes, it's being used. Yay! Thank you!
