The library in my hometown has a blog, which I read because it's well done and because it's a way for me to stay connected with where my family lives.
I particularly enjoyed one recent post. Someone found a photo in the library's historical archive that had been later doctored for use in a promotional book.
Check the original post for bigger photos. It is interesting to see how the photo, circa 1900, could be altered so well - as opposed to some of the bad work being done now with Photoshop.
This shows that fun can come from library archive, especially photo archives. Also, too, the subject of the photo is interesting. It's the dock of Cedar Point, an amusement park in Sandusky, OH. And I am always amazed at how dressing nicely was just a matter of course in that era. People at Cedar Point don't dress like that anymore.
