This is what a working Zotero Library looks like:
Each column of your Zotero Library helps you tackle certain activities, from organizing the overall library to updating item-level details.
The left column contains your Libraries and Collections and the Tags box. This column helps you organize your overall Zotero Library.
The middle column lists the items in your Library. You can view all the items in your Library (by clicking My Library in the left column), or view items by Collection.
The right column displays bibliographic details about each article or item under the Info tab. It's always a good idea to double check author names or other citation details as you add new items. You can also view or add your own Notes or Tags about each article using those tabs.
Organize your items in folders (called “Collections”) by classes, subjects, or projects in the left-side column.
To create new Collection, right-click on My Library (see image at left) or click on the New Collection icon that looks like a yellow folder with a green and white star on it.
You can drag and drop your folders/collections to organize them as you build. Add items to Collection folders by dragging and dropping them from the Item List (middle column) or indicating the Collection folder when you use the Zotero Connector to add new items.
To edit an item's Info details, click into a specific detail in the "Info" tab in the right column. In the example at right, the user is clicked into an author's last name, which has opened an editable field.
Whenever you add new items to your Zotero library, it is a good idea to double-check and fix any problems with the item's details.
To adjust which details you view about the items in the middle column, click on the options icon on the top right of the middle column. The Title will always display. In the example below, the user has also chosen to display the Creator, Item Type, Year, and Attachments for each item in the list. Rearrange the details order by dragging and dropping on the top line.
In the right-side column, you can also view or add your own Notes or Tags for each article using those tabs.
Tags added to specific items in the right-side column will be organized and accessible in the left-side column Tags box (below the "My Library" Collections - see image below). Zotero will also automatically assign Tags from keywords or other metadata related to the items you save. Using the Tags box in the left column, you can sort or search all items in all your Zotero libraries by keywords or subjects.
