Hi Krwright,
thanks, i will take a look on the internet. Yes the book i had for spanish was as big as my hand and weighted like 100-200, was perfect for travel. Looking for the same in russian, preferably in dutch - russian but english russian works too. But the berlitz sounds promising.
Coffeecup, when i travel i never take a computer or smartphone with me, so your sollution wont work for me, probably for other people it could be very usefull.
