Hi RussianGuy,
I've not tried the Lausanne library, but from this link, you can search their catalogs:

Apart from that, there are several books shops in Lausanne that have English sections, and you can always order from Amazon...although you may get hit with tax when getting it delivered.
It's a big decision to make, but for me personally...I have never regretted leaving the UK for here.
Best of luck with your decision, and enjoy the port!!
