Newspapers on Microfilm
Because of their fragility as they age, newspapers have traditionally been preserved by microfilming them.
Microfilm is located in the Newspaper and Microfilm Room in 40 Doe Library and in Bancroft Library. Newspaper films are arranged geographically within the News/Micro collection [floorplan.pdf]
Reader/printers allow you to read the films and those in News/Micro allow you to save pages to flash drives in .jpg and .pdf format.
Most newspapers do not have indexes. How do you find articles by subject? By knowing the approximate date of the event you are studying. If you don't know the date, you can use the index to a different newspaper as a way to find out.
