The Central Library location of the Buffalo & Erie County Public Library has a wonderful local history collection. Check out the Grosvenor Room for your local history questions.
Newspaper articles available in the library databases are current and go back in time, but probably don't go back to the era of the opening of the historical site or museum you choode to visit. Still, you will find they make the news occassionally.
