walking encyclopedia

I found her most intelligent and so far as my career on and off the stage was concerned she was a walking encyclopedia.

Blind Tom's memory was a blank on most subjects, but he was a walking encyclopedia on music.

He knew precisely what she would say; Ann was a kind of walking encyclopedia of the conventions.

As a "professor" I always felt myself a sham, with its chief duties of being a walking encyclopedia of erudition.

In fact I was a veritable walking-encyclopedia filled with a mass of information, most of which was of no earthly account.
