## Use Case

[HAL, archives ouvertes](https://hal.archives-ouvertes.fr/) is is an open archive where authors can deposit scholarly documents from all academic fields ([See more on Wikipedia page](https://en.wikipedia.org/wiki/Hyper_Articles_en_Ligne)). It's very used in some research field as mathematics or computing, in France but also worldwide.

The HAL logo could be used of a link to an "author" page (a person or even a lab or a university), regrouping every of his/her/its publications. It's quite the same as other initative such as [ArXiv](https://arxiv.org) for example.

## PR?

I built a SVG file corresponding to the "favicon" version of the logo (the last one), if you believe it might fit ForkAwesome, I'll be happy to PR it!
