The Chicago History Journal has a lot of information on its pages. The site is approaching its two year anniversary in November, and the posts and links have piled up. Add the three satellite sites - the Online Library, CHJ YouTube and the links pages - and it really begins getting tricky and time consuming to find out if I have information on your selected topic.
The new Google "Search" box at the top of the left column should help. Type in a topic, hit search and a list of relevant posts on the Journal appears. But wait! There's more! There is a second tab that indicates where the information can be found on the satellite sites also. One click and you scour all three blogs. Love it. Hope you find the new feature useful.
