I cannot understand why you are adding numerous specialist titles but have still not done this title apart from the year 1910. It is the only continuous publication for this large industrial town, from 1858 to the present. Some news items are found in two Sheffield titles, but not all. I know you have it because the library purchased microfilm from you at an early date (1970s?) and did not hold hard copies of 1858-77 until 2-3 years ago when the Advertiser emptied its store.
I have needed to use the microfilms for family notices 3 times recently. They are becoming very worn (50 years' use) and due for replacement if scanning were not available.
