To get started with EndNote Online, you have 2 options:
Go to Web of Science and set up an account. Then click on tab for EndNote. It's the same account. I'm not sure this still works to set up an account.
(2) If you're on campus, you can instead just go straight to https://www.myendnoteweb.com/ and set up an account. You can then access the account off campus for a year, until you need to update it on campus again.
You might want to use computer-based EndNote as well. See the EndNote X6/X7 page. To link the accounts, In EndNote X7, in Edit >> Preferences, look for Sync and activate.
Update -- Online EndNote says it's free to anyone now. If you sign up or sign in on campus
or using Web of Science, you'll get 5GB storage for PDFs and notes, up from 2GB, and many more citation styles.
It's easy to gather citations from Ebsco databases (e.g., Quick Search) and Web of Science. For other databases, Google Scholar, and the Library catalog, it's not easy.
But it's easy to transfer items from EndNote X6/X7 to EndNote Basic. In EndNote X6/X7, go to Preferences and update Sync with your EndNote e-mail and password. Then you can Sync citations back and forth between computer-based and web-based.
(See the EndNote page for help on getting the references into EndNote.)
Ebsco databases (Academic Search Complete, PsycINFO, Environment Complete, and others)
There are 2 ways to do this: One, collect multiple citations using "Add to folder"
and then use "Go to: Folder View."
The other way is to collect the citations one by one. Click on the blue article title to get the article record.
Whether you are in Folder View or looking at the individual article page, look for the Export icon in the column to the far right.
Now you should get the Export Manager. It defaults to the EndNote/RIS choice, but change to EndNoteWeb and then click "Save" on left.
You should see the information pop up in your EndNote Web window. Sometimes it's slow. (Capture the PDF full text at this time, if it's available. More on that later.)
Web of Science
Sometimes you'll have difficulty getting a citation into EndNote Basic. One option is to find the same thing in another database, catalog, or search engine and try again. Another is to save the citation as a RIS file and then import into EndNote Basic. (The last option is to copy and paste into a blank "New Reference" form!)
Import into EndNote Basic.
On your EndNote Web window, go to your reference in "My References." Click on the paper clip icon and the on "attach files."
Then hit the "Choose File" button, find the PDF file, and "Upload."
You will then see a darker blue-colored paper clip for that reference.
These guides are clear, up to date (for now, Jan.2015), and comprehensive.
