We review and update the title list for Catalyst Core and the add-on packages twice a year. Our main update takes place in June, and then in the following January for a small number of titles that published after June. Catalyst titles are available in the Sage discovery layer here, and the Marc Records available for download via Secure Centre here.

In our bi-annual update, new editions and additional new titles are added to Catalyst Core and the add-on packages. We also remove a small handful of titles – either where we no longer have author permission to include the title or where a title has such low usage that we want to replace it with a more relevant title in order to add greater value to the package.  All updates across the packages are done simultaneously.
