I'm interested in helping improve the information in wikidata related to physics subject matter and to research institutions.

I may be testing some things in a test area.

My thoughts on Wikidata's User:ArthurPSmith/5th Birthday.

I've had 100,000 edits (28 Feb 2018)! And 1 million as of 28 June 2019... (mostly thanks to Quickstatements and the author disambiguator...)

Note that I've worked for the PHYSICAL REVIEW D (Q869847) journals of the American Physical Society (Q466113) since 1995.

I also seem to have my own Wikidata item now: Arthur Smith (Q56526504).

Some tools I've used so farEdit

Some tools I'm responsible for (to at least some degree)Edit
