The Public Library is in the same area as the County Museum.
Scooby-Doo, Where Are You!
The gang went to the library to find information about the special glasses that Scooby found at the County Museum. A reference book revealed that the glasses were made in England and were commonly used in a few specialized professions, such as archeology. This suggested that Professor Hyde White had been at the Museum and prompted the gang to return there to search for clues.
