What do I do on commons and how can I help you ?Edit

Graphics: statistical and geographical dataEdit

I am happy to help if you have data to plot... I can also produce geographical maps of Switzerland containing statistical data.

Music sheetsEdit

I have started to play with Lilypond to engrave some music; quite powerful (and fun to do !). If you need some help with engraving music (e.g. from a bad quality scan), don't hesitate to ask me, I'd be happy to do a bit more of this kind of work.


I try to take pictures, but I am not so good at it. I have uploaded a few, but try to restrict myself to those that are really useful for a Wikipedia page.

Old documentsEdit

I try to get old, public domain, documents of encyclopedic interest, scan them and add them to the relevant articles.

Free imagesEdit

I try to get authorizations to upload free images of encyclopedic topics; I have been pretty lucky so far with the Swiss Federal Administration, which gave authorization to upload picture of all past and present federal politicians, as well as some other pictures.
