I got an email today from Elsevier:
It is our pleasure to inform you that your publication has been cited in a journal published by Elsevier.
Through this unique service we hope we can offer you valuable information, and make you aware of publications in your research area.
The service is called CiteAlert. It sends you an email every time you’re cited!
Clearly, it’s little touches like this that justify the price gouging and subscription bundling. Kind of like the little chocolate on your pillow at the expensive hotel.
