If you have saved your searches as suggested in Document your search strategy, you will be able to re-run them when you need to update your review.

In some databases you can set up a search alert for your search strategy so you can be emailed when any new articles are added to the database. You should also be able to set up Table of Content alerts from the major journals in your field.

For instructions on how to set up alerts in the major databases and database platforms, see the Library's Keep up to date with new resources webpage.
