EndNote is reference management software with features to—
Synchronize your references between up to three personal computers, an EndNote Web library and your iPad or iPhone through the EndNote Sync command. (You must be the owner and user of all three computers.)
Set up a sharing team to grant access to your designated synced library and effortlessly collaborate with up to 400 co-authors and colleagues.
Cite your references in word processor documents to create formatted citations, bibliographies or independent reference lists.
Apple's macOS versions 10.12 (Sierra), 10.13 (High Sierra), 10.14 (Mojave), 10.15 (Catalina), 11 (Big Sur), 12 (Monterey) and 13 (Ventura) contain features to save the contents of the Desktop and Documents folders in iCloud and to "optimize" storage by storing less-used files only in iCloud online. EndNote libraries stored in iCloud, even when existing on both the hard drive and online, are subject to corruption over time. If you choose to store your documents in iCloud, we suggest creating a separate folder in your Home folder dedicated to saving your EndNote libraries there. Do not store EndNote libraries in iCloud or any other cloud-syncing folder; do not store EndNote libraries in the Documents folder if you have selected the option to synchronize documents in iCloud.
You can find more information on these features on the Apple support site at these locations.
General library safety notes
EndNote libraries consist of two parts: the enl file and the Data folder. You must keep these two components together at all times; both are essential for the library to work correctly.
Keep EndNote libraries on your computer's local hard drive. Storing and editing libraries on a network drive can lead to corruption and performance issues.
You should never store active EndNote libraries inside cloud-syncing folders such as Dropbox, OneDrive, Box, SugarSync and others. Syncing folders such as these will significantly increase your chances of encountering library corruption.
Though not a requirement, we recommend uninstalling your previous version of EndNote before installing a new version.
Synchronize references in EndNote libraries between desktop and laptop computers, an EndNote Web library and an iPhone or iPad using Sync.
Share complete EndNote libraries with other EndNote desktop users through EndNote Sync and Library Sharing.
