MOT
This is an excellent dictionary
that works best in the university network. Click the plus sign ("Luo
usean sanakirjan ryhmä") and choose all the English dictionaries and the
ones that have some relation to your field, then you can get better
results.
You can also access the dictionary through the library intranet pages (utu.fi/kirjasto -> Volter).
Type "MOT sanakirjasto" to the search box and after the search you
should be able to access the dictionary by clicking "MOT sanakirjasto
(vanhempi käyttöliittymä/older user interface)". This older user
interface is more thorough and reliable than the newer version
sanakirja.fi (which you can use with your utu-credentials).
