EndNote is a commercially developed and maintained product. That means that there is a charge to buy the desktop version of the software (the less sophisticated web version, i.e. EndNote Basic/Online, is free) but also that Clarivate, the company behind the software, provides user guides and help.
EndNote frequently releases new versions. Look for the notes specific to your version. Images in this guide are mostly for the EndNote 20 version.
