Social cataloging application

A social cataloging application is like a special bookshelf that you can share with your friends! You can add books, movies, or other things that you like to this virtual bookshelf, and your friends can see what you added. It's like when you show your friends your favorite toy or game, but with a lot more things to share! You can also look at your friend's bookshelves and see what they like too. It's a way to connect with others who have similar interests and discover new things to enjoy together.
