What is the Catalyst new editions solution?

What does this look like?  

How does this effect my textbook?

• If you are using a Textbook with no new edition, then no alert banner will appear, and you are using the most up to date version.
• We retain two different editions of a textbook alongside each other for a period of 12 months, to allow you enough time to transition to the latest edition in your teaching. If you are using a title which has a new available in Catalyst, the old edition will be retained (both in your library’s catalogue and in your institutions unique discovery layer) for 12 months from date of new edition being added. We add new editions to the Catalyst collection in June and January of each year, based on publication dates.
• If you are using the Talis Elevate teaching and learning functionality and have elevated a chapter from an older edition by adding it into your module(s), you are able to retain this chapter. The elevated chapter will not be deleted even when the old edition is removed from the Catalyst collection; it will stay as part of the module. However, once the old edition is removed from the collection it will not be available to add to any future modules.
