Organize the information in your Zotero library using folders, also called collections.
Your My Library collection has all the things you add to your Zotero Library. Even if you add an item to another folder, it will always show up in your My Library folder.
You can drag and drop items from My Library to any folder, also called a collection. Just click, drag, and release the item into your chosen folder.
You can also add directly to a specific folder by first clicking on it to highlight the folder. This tells Zotero to add items to a specific folder in your library.
