Once you have added an item to your Zotero library, you can begin organizing your research using collections and tags.
Collections allow you to organize your items into groups and subgroups. Importantly, the same item can belong to multiple collections and subcollections at once. Collections make it easy to organize your sources by project, class, topic, or even section of your paper.
Tags (think: keywords) provide a quick, searchable way to describe and categorize items. You can tag items based on their subject, methodology, status, ratings, or your personal workflow (e.g., “needs review”). Items can have as multiple tags, and you can filter your library (or a specific collection) to only show items with selected tags.

Creating a Subcollection:
Note: Items in Zotero can belong to multiple collections. Any change made to an item in one collection will be reflected across all the collections it appears in.
Deleting Items from Collections
To remove an item from a single collection:
To delete an item from your entire Zotero Library:
Managing Duplicate Items
If you notice duplicate entries in your Zotero library, do not delete one manually, as this may remove it from collections where it's needed. Instead, use Zotero’s Merge function:
Deleting Entire Collections from Zotero
If you decide you no longer need a collection or subcollection, Zotero offers two deletion options. Be sure to choose the one that fits your needs:
Tags
Tags are like keywords that you can assign to items in your library. They are typically used to describe the subject or topic of a citation, but you can customize them to fit your workflow. For example, you might tag items based on the project they belong to (Hist210_Paper1), their status (read or unread), your personal impressions (useful or useless) or use a custom research code (Review_For_Introduction).
Tags are searchable through the Zotero search bar and can be viewed in the tag pane, located in the bottom-left corner of the Zotero Window.
Tags can be imported automatically from databases when saving citations or they can be added manually. Be aware, if you allow automatic importing, your tag cloud may become cluttered with inconsistent tags, obscuring your personal tagging system.
Adding Tags
To tag an item manually:
Tips:
Tagging Multiple Items at Once
To confirm the tag was applied:
Zotero automatically saves PDFs along with citations when possible. You can adjust this behavior in the Preferences menu if you prefer to manage attachments manually. Keep in mind that attachments take up space in your Zotero account—Zotero provides 300 MB of free storage, and additional space can be purchased if needed.
Manually Attaching Files
You can manually attach files (such as PDFs, images, or audio recordings) to items in your Zotero library in two ways:
Drag and Drop Method:
This is the easiest way to attach a copy of an article, screenshot, or other resource to its corresponding citation.
