Finnish Libraries are using a software for their E services (like borrowing books online, finding a book in a library....) I want to know which software…

In Helsinki City Library, we use Sierra by Innovative Interfaces (https://www.iii.com/products/sierra). It’s a commercial software. You can find more about the library systems used in Finland at http://www.kirjastot.fi/fi/kirjastoala/kirjastojarjestelmat#.V1Wlz015I5t. Especially Koha (http://www.koha.org) is interesting as it is an open source software.

Our E-book systems have been integrated to Sierra, but they use different commercial sites. They are OverDrive (https://www.overdrive.com/) and Ellibs (http://www.ellibs.com).
