One of the resources available through their website is a fantastic research guide called "How to Research the History of Your House or Neighborhood." The guide divides the search into phases ("Where do I start?") or you can search for a particular business, architect, or theme. Going further, it explains where and how to find maps and pictures.
The full link to the guide is: www.baltimoreheritage.org/resources/research-guide. I recommend you check it out!
