Guidelines – Content Decision on what content should be on a roll How many months, issues, years and titles are grouped on one roll. For example, you dont want to combine a single issue for 1889 on the same roll as 1890 issues. If there are no other issues for that year then and only then would you combine a single issue from a different year. Think like a researcher and be consistent. Records Management Center30
31
Guidelines – Cini vs. Comic Decision on the direction of film should be on a roll Top Cini Top Comic Records Management Center31
32
Guidelines – 10x? 20x? Decision on the reduction ratio As the reduction ratio is increased, the smaller the print will be on the reader. If the newspaper is older or in bad condition, the lower reduction will be used when possible. This will increase the size of the print making it easier to read. If the newspaper is newer or in good condition, any reduction or direction of filming can be used as long as the document is in focus and centered. Records Management Center32
33
Guidelines – Copyboard Consistency of placing documents on copyboard Make sure there is always at least 1 to 1½ inch border around the documents. Finder light illumination area Records Management Center33
