ADS and the Open Journal of Astrophysics
Most if not all of the authors of papers published in the Open Journal of Astrophysics, along with a majority of astrophysicists in general, use the NASA/SAO Astrophysics Data System (ADS) as an important route to the research literature in their domain, including bibliometric statistics and other information. Indeed this is the most important source of such data for most working astrophysicists. In light of this we have been taking steps to facilitate better interaction between the Open Journal of Astrophysics and the ADS.
First, note that journals indexed by ADS are assigned a short code that makes it easier to retrieve a publication. For reference, the short code for the Open Journal of Astrophysics is OJAp. For example, the 12 papers published by the Open Journal of Astrophysics can be found on ADS here.
If you click the above link you will find that the papers published more recently have not got their citations assigned yet. When we publish a paper at the Open Journal of Astrophysics we assign a DOI and deposit it and related metadata to a system called CrossRef which is accessed by ADS to populate bibliographic fields in its own database. ADS also assigns a unique bibliometric code it generates itself (based on the metadata it obtains from Crossref). This process can take a little while, however, as both Crossref and ADS update using batch processes, the latter usually running only at weekends. This introduces a significant delay in aggregating the citations acquired via different sources.
To complicate things further, papers submitted to the arXiv as preprints are indexed on ADS as preprints and only appear as journal articles when they are published. Among other things, citations from the preprint version are then aggregated on the system with those of the published article, but it can take a while before this process is completed, particularly if an author does not update the journal reference on arXiv.
For a combination of reasons, therefore, the papers we have published in the past have sometimes appeared on ADS out of order. On top of this, of the 12 papers published in 2019, there is one assigned a bibliometric code ending in 13 by ADS and none numbered 6! This is not too much a problem as the ADS identifiers are unique, but the result is not as tidy as it might be.
To further improve our service to the community, we have decided at the Open Journal of Astrophysics that from now on we will speed up this interaction with ADS by depositing information directly at the same time as we lodge it with Crossref. This means that (a) ADS does not have to rely on authors updating the arXiv field and (b) we can give ADS directly information that is not lodged at Crossref.
I hope this clarifies the situation.

Peter, what about inspirehep.net? Are you in touch with them? Are they familiar with OJA? They archive most astro-ph papers

They have picked up most OJA papers. Indeed they seem to do so more quickly than ADS!
January 20, 2020 at 1:55 am
Yes, but for some of them the paper is not correctly indexed. For my latest paper, I had to email them to include the doi.

I see also that ADS has not yet managed to aggregate citations for the Feroz et al paper, which is presumably connected to the issue you mention.
I check a few papers ion inspire.hep yesterday and according to that source the Feroz et al. paper has 327, which I think is an underestimate! Let’s see what appears on ADS when it finally appears.
Incidentally, your OJA paper has not made it onto ADS yet but is already on inspire.

Inspire’s coverage of astro papers is not as consistent as ADS but people who work in astroparticle physics etc seem to use it a lot.

I think it takes time for the arXiv bibcode to change ADS bibcode after the paper is accepted. (however somtimes you need to email them.They had not done it for a 2014 paper and emailed them).

It must be in the process of updating..

I don’t think Perlmutter has worked in Particle physics (even though that seems to be a lore). Many people who started and graduated in Particle physics switched to astrophysics early on: such as Joel Primack. Others who worked in (theoretical) particle physics, but also work on astrophysics are Glennys Farrar and Lisa Randall (recently).
Of course there are zillion particle physicists who have worked on models for dark matter and dark energy
After SSC got cancelled many (astro)-particle physicists switched to LIGO (including its first director and 2017 nobel Laureate Barry Barish). Many (experimental) particle physicists have played leadership roles in some of the most famous astrophysics experiments such as SDSS, DES, DESI, LSST various CMB experiments etc.

ADS had problems over the weekend. It probably didn’t do its regular update. It lost all citations and reference information.
January 27, 2020 at 12:53 pm
No, I meant that there was an warning message up at the weekend saying they had problems with citation data, etc.

It’s very frustrating, but I think they’ll fix it in the end. Possibly.

My citation numbers are highest on Google Scholar, so it’s obviously the most reliable source.

Most of Shakespeare’s plays weren’t written by Shakespeare but by someone else who had the same name.

Yes, I noticed that yesterday.
