My most useful #academic #geek #tip, after many years, is still this: if you know the #DOI, a simple web query can get you the full citation (thanks to http://doi.org and the magic of "content negotiation"). So in bash/#zsh I have this in my init file:
function doi2bib() { curl -sSgLH 'Accept: application/x-bibtex' "http://dx.doi.org/$1" }
so I can simply type "doi2bib 10.1111/ddi.13271" and get the #bibtex :D
