Card catalog

Okay, imagine you have a big collection of toys. Wouldn't it be hard to find the exact toy you want to play with if there's no way to organize them? That's where the card catalog comes in!

Like a big toy box, a library has a lot of books that need to be organized so people can find them easily. To do that, a library uses a card catalog.

A card catalog is like a big filing system for books! Each book has its own special card with important information on it, like the book's title, the author's name, and where the book can be found in the library. These cards are stored in alphabetical order in little drawers, usually organized by category, like "fiction" or "non-fiction".

So, say you're a little kid looking for a book about dinosaurs. You can go to the card catalog and look under the "non-fiction" drawer and find the "D" section for dinosaurs. There, you'll see a bunch of cards with information about different books about dinosaurs. You can pick the one you want and the card will tell you exactly where to find the book in the library!

Overall, the card catalog is like a giant index for books in the library. Thanks to the card catalog, finding the perfect book to read is as easy as finding your favorite toy in a toy box!
