From the Bapst Library of Boston College:

These examples will show you a little variety.  "How to Begin a Research
Paper in Art History" will give you an example of one with a little
narrative text mixed in.  Many of the others are just boring lists of
titles with call numbers - I think those would be fine for a scholar but
would they spark a child's interest in reading?

A Waterloo Public Library Genealogy pathfinder:

Not too bad.  Still in the list of books & sources mode...doesn't anybody
annotate these things?
