The library is free to all. You don't need to be a resident of Estonia to borrow, anyone can pick up a book and take it with them. There are no membership cards, due dates or late fees. You simply borrow a book then return it on your next trip to Tallinn. The library is fully self-service, open 24 hours a day.
One of the things that makes this library so special is the fact that the airport did not pay for a single book on the shelves. The collection of books came purely from the generous donations of Estonian citizens and visitors to the country in the spirit of sharing from one traveller to another.
The library is divided by language into several sections - books in Estonian, English and Russian languages as well as children's books and books written in other languages.
It is encouraged that all books donated to the library have a dedication on the front page, perhaps mentioning where the book has been or any other nice thought for the next reader.
This innovative library has proven to be a great success with its stock list continuing to grow all the time.
