Improtant note: Always check your citation against the actual item (the article, book, etc.) to make sure it is correct. Do not use data from the record to verify as there may be missing information or errors in some cases.
You can choose to export individual items one-by-one to a citation manager (EndNote or RefWorks) or create an RIS file to upload to other citation managers.
You can mark items using the pin icon when viewing your results list:

When viewing the pinned items, you can click on the three dots at the top of the screen and get the same options that you can get for a single item (see above).
