Zotero provides the ability to save references from library catalogs and article databases with one click. The library you create in Zotero allows you to organize and edit the entries.
Collections: The left column includes My Library which contains all items. Clicking the button above the left column creates a new collection, a folder into which items related to a specific project or topic can be placed.
Below that is the tag selector where tags assigned to items can be added or removed.
Items: The items pane displays a list of all the items within each collection/folder with icons indicating the type of item (book, article, thesis, webpage, etc.)
Item Details: This pane displays the bibliographic information that was imported by Zotero for each item. Each field can be edited. There are also options to add additional notes, attachments, links to the original sources, tags,and subject headings.
