I found this 5-page handout rather useful.
Literature Search: A Librarian’s Handout to Introduce Tools, Terms and Techniques co-developed by Katy Kavanagh Webb, Head of Research & Instructional Services at East Carolina University’s Joyner Library, and Library Connect newsletter of Elsevier.
Each page of the handout can stand alone or be used together as a teaching tool that covers:
- Keywords, operators and filters
- Search tools
- Types of literature
- Evaluate information
- Organize research
You may download the handout in PDF here.
“It’s not a replacement for librarian-led instruction,” says Katy, “but it can act as a calling card to introduce key concepts or as a leave-behind visual reminder to continue these best practices when we librarians are no longer in the room.” (Library Connect April 7, 2017)
It’s a polished product and has a lot of good features. If you go to the Elsevier page for it there is also a poster version. https://libraryconnect.elsevier.com/articles/literature-search-download-helpful-handout-library-users-their-most-desperate-hour
What I would REALLY like is to have a modifiable version I could tweak for my setting.
