The original L-Space application was for tracking the status of the books in my Discworld collection: Which do I own, how many have I already read, which ones are still missing, and also for the Dutch language please Over time it got more and more features: Instead of only a list of books for a single series, you can tag which ones you own and which ones you have read, plus background information like the characters and themes of each of the books. Also the titles of non-English languages like Dutch, German, French, Spanish and Portuguese were added. This app contains the list of Yoko Tsuno by Roger Leloup
