To ensure no loss of data from your library, it is wise to backup your Endnote library (sometimes called 'archiving' or 'compressing'). View instructions from RMIT University Libguide on how to backup your library via the link below or watch the video from the EndNote YouTube channel.
Once all databases have been searched and records downloaded into EndNote you must identify and delete duplicate records. This is because articles are likely to appear in multiple databases and if you have two (or more) copies of the same article in your EndNote library, it can cause problems when you start working in Word.
For example, if you reference one version of the article in the Introduction and another in the Discussion section, you will end up with two copies of the reference in your bibliography.

By nature, systematic reviews have a large set of records and it's essential to ensure that you don't accidentally remove any 'false' duplicates. Talk to your librarian about options for de-duplicating large sets of records, or use a method such as the one developed by Bramer et al. (2016).
