In most article databases and library catalogues you can easily send references to EndNote. Often, it is possible to mark and send several records at the same time. Look for an option to send or export references directly to EndNote or in RIS-format.
Depending on your web browser and the database that you are using, a pop up window may appear. Choose Open with EndNote or ResearchSoft Direct Export Helper.
Example from Scopus and Firefox. Choose Open with to send references directly into EndNote:
Direct Export does not work well with safari and the downloaded file cannot automatically be opened with EndNote. Some alternatives for Mac users:
It is a good idea to choose Full Record under Record Content, when you export references from Web of Science. This way, DOI numbers, abstracts etc. will be included in your references.
Abstracts and DOI numbers are not always included when you send references from Google Scholar into EndNote, so if possible, use other databases as your first hand choice.
Make this setting to be able to send references to EndNote from Google Scholar: Go to Google Scholar settings. Under "Bibliography Manager" select the option "Show links to import citations into" and choose "EndNote" in the drop down box. Click on the "Save" button.
