If you've exhausted the sources on the Legislative Documents tab, but still need more information there are some non-traditional legislative research sources you can try.
The Delaware Public Archives has a collection of primary materials and records of the General Assembly. These include audiotapes of House and Senate floor activities, bills, individual legislator's papers and other records.
The national press rarely covers Delaware legislation but local Delaware newspapers can be a good source of information. Nineteenth and early twentieth century Delaware newspapers covered the activities of the General Assembly in greater detail than the modern press. The Delaware Law School Library does not have any back issues of Delaware newspapers but several local libraries do. There are also some online archives of Delaware newspapers.
