Zotero

In most online resources, Zotero automatically detects when you are looking at information for a book, article, or other source and inserts a "save reference" icon right into the address bar. The address bar icon will look like a book, document, newspaper, etc. To save, simply click the icon. If you are looking at a list of references, you may see a folder icon. This icon will prompt you to select multiple items from the list to save.

From scholar.google.com 

Zotero senses a list of items, so the 'folder' icon is displayed. You will be prompted to select items to import to Zotero.

In an article database, e.g. PubMed

Zotero senses a single citation, so the 'article' icon is displayed.

In the library's BobCat catalog 

Zotero sees a book citation, so the 'book' icon is displayed.

In EBSCO Hosted Databases:

1. To save a citation within an EBSCO database, move cursor over magnifying glass and 'Add to folder.'
2. Click on Folder to view saved items.
   • 
3. In the Folder, Select items.
4. Click 'Export.'
   • 
5. Select the option to 'Direct export' to Zotero.
6. Open Zotero, and highlight the Zotero 'library' you want to save to.
7. Click 'Save.'
   • 

If Zotero does not automatically detect (provide a "capture icon" for a list, book, or article) to  import a reference into your library you can use the export  feature provided by the database.

• SAVE the items in the database (using the "clipboard," the "marked list," "folder," whatever the database shopping cart is called.)
• Next, look for an option to EXPORT from the list. Choose the "RIS" format. References may automatically save into Zotero, or you may have to go back into Zotero, then click the Zotero gear button and choose "import".
