fyi I've just asked [What are the main ways that pulsar "glitches" are noticed and documented? Do they have to be caught in the act of glitching to be catalogued?](https://astronomy.stackexchange.com/q/48994/7982)

<p>Besides listing which pulsars have ever actually glitched, it would hopefully also include some historical data on their periods before and after they glitched.</p>

Is there any well-populated list or database of pulsar "glitches"?

There are two substantial (~650 entries) glitch databases I'm aware of, [one maintained by Jodrell Bank](https://www.jb.man.ac.uk/%7Epulsar/glitches.html) and [one maintained as part of the ATNF's pulsar catalog](https://www.atnf.csiro.au/people/pulsar/psrcat/glitchTbl.html). Both list similar information for each glitch, including the glitch MJD (with ATNF's values sometimes being more precise) and the fractional changes in spin frequency and frequency derivative.
