any paid / free apps to maintain and manage personal library ?

I currently use **Goodreads** to track my book collection, but I am looking for a more advanced solution. Specifically, I am interested in an app or software that offers enhanced features such as: * Barcode scanning for easy book entry * Customization shelves or categories * Cloud syncing across multiple devices * Advanced search and filtering options (e.g., by author, publication date) * Integration with external data sources (e.g., reviews, library catalogs) I would appreciate any recommendations for both paid and free apps that can offer these functionalities. Thank you in advance!
