Hacker News Reader

I think in content intented for long term it is always better to use the canonical address, possibly in a footnote if it is too long.

Better yet also include an alternative link to an archive like https://archive.li/ or similar.

I hope you added the entire link in an appendix, otherwise it’s not Google’s fault for ruining your paper.

The query itself is available in a screenshot. Also a pretty periferal part of the paper.

Looked/thought hard about options but did not come up with better at the time.

But wanted to highlight how important it is for parties starting such services to have a plan for longevity. Hopefully Goog will keep old links going for a long time.

Please consider using DOI’s for this http://www.doi.org/factsheets/DOIKeyFacts.html

Agreed. Figshare is a good service for this. In addition all the publishing infrastructure is in place.

Great idea! I'm using figshare but neither me nor colleagues got to think about that.
