I send out a slide every week with tech tips, ideas, resources, etc. for staff.  Some weeks I posed original ideas mixed with curated resources.  This one is all curated.  Feel free to copy and modify.  I did not keep the link to the slide that has a table with all our paid databases. You could add a slide to your databases instead.
