The students are allowed to look at the books as they are being discussed. Students need a checklist, with room for notes, not a bibliography. Each source is shown to the students. I made pencilled notes in some sources, e.g. where the explanation page is. Each class takes about 45 minutes.
Small groups are fine - they get to spend more time with the sources.
The checklist exhausts people - makes them realize how the process works and how extensive it can be. Nothing horrible has ever happened in the classes. There has been good feedback from students and administration. The classes are just BI built into a little jewel. Press releases about the classes are always printed in local papers, often tied in to local arts festival.
