A Pvblic Library?

A Pvblic Library! Why was the 'u' substituted by a 'v' on the facade of Yorkville library branch at 22 Yorkville Avenue? The front desk was not sure about that so she contacted a senior staff member. It turns out that it is true for most of the historical buildings. In old English and Latin, the letter 'V' was considered sufficient for both sounds. The letter 'U' was introduced at a much later time. This is certainly an example where the past is preserved in stone.
