Brooklyn Daily Eagle 1852-1902 It's a very interesting experience. Via Shelflife, this article explains a bit more about it:
"The Brooklyn Daily Eagle, founded in 1841, was Brooklyn's newspaper of record. During the Civil War it was the most widely read afternoon newspaper in the nation, gaining prestige as the century drew on. The vast repository contains vibrant reporting on local and national events through a period of enormous growth. It is also a rich resource for illustrations and photographs."
"Naturally, the demand for digitizing 1902–55 of the Eagle is very high, since these recent years cover the lifetimes of many people's close ancestors. But several issues need to be resolved. First, web access to newspapers after 1923 presents copyright complications, which lawyers are now reviewing."
A enjoyed flipping through it like a clipping from 1902, Decemeber 5th or you can read the sports section before basketball was invented or about the solar system before Pluto was discovered.
