Favorite library connection??

Question:

Favorite library connection??

A win-win challenge, I hope-
What is the link to a favorite library online that has cool genealogical goodies? Hidden treasures?
Newbies, you too can play... if you don't yet have a favorite, try to find if your local library has anything special to offer, or maybe I can nudge you to check out what your State library has. The Texas state archives, for example has a data base of original land grants for the whole state. Note... this challenge is not limited to US sources.
Looking for some smiles. Looking for some "wow, I never thought of that". Something to benefit lots of people.
