I have recently found a large number of my childhood books, most of which are in japanese, english and some rarer ones are in Danish. There are also some very old (but good quality) Finnish books. Most of them are childrens books or education books, but there are some which grown-ups might enjoy. Such as books about kaleidoscopes, jewels, etc. Anyway, I'm having trouble finding places where I could donate/sell these foreign-language books. I don't wish to just throw them away, as they were quite expensive and I think if I find the right customers, they could be put to great use. Any tips or suggestions?!?
You could give those books to Pasila Library in Helsinki. In Pasila Library, we have Multilingual Library with books in many languages not usually found in Finnish libraries. Without seeing the titles, I can’t say if those books were suitable for your collection.
For more information about Pasila Library, please see at http://www.helmet.fi/en-US/Libraries_and_services/Pasila_Library.
Of course, it’s possible to sell those books to second-hand bookshops, but this may take much time. Many of them aren’t very interested in that kind of books. Second-hand bookshops in Finland can be found at http://www.tie.to/antikvariaatit/ and http://www.antikka.net.
