Can I have a list music CDs in Helsinki main (or other in other libraries as well) which are related with Cuban (Cuba) music? In which library and where in…

You will find our bibliographic database at http://www.libplussa.fi/#en .
Go to the "Basic search" . Choose "Subject heading or class" and type "Kuuba" as search word. In the menu "Display All kinds of items" choose "Only CDs". Search.
(Unfortunately you have to use subject headings in Finnish, because our bibliographic records are in Finnish. If you choose title search you can also type Cuba# in English - note the truncation mark - but in that case you will get less references and not all of them are necessarily relevant.)

In the database you will also see the availability of the CDs in different libraries. The largest music collections in general are at Pasila Music Station, Töölö, Itäkeskus and Kallio libraries.
