'Vinegar syndrome' refers to the degradation of silver halide crystals on microfilm.
Answer: False
'Vinegar syndrome' describes a chemical decay process affecting cellulose acetate film bases, leading to the release of acetic acid and subsequent film degradation, rather than the degradation of silver halide crystals.
Redox blemishes on microfilm are typically small, yellow or orange spots caused by oxidation.
Answer: True
Redox blemishes are characteristic defects on microfilm, appearing as small, often circular spots ranging in color from yellow to orange or red, resulting from the oxidative degradation of the film's emulsion.
Diazo and vesicular films are preferred over silver halide for archival master negatives due to their superior stability.
Answer: False
Silver halide film is generally considered superior for archival master negatives due to its inherent stability. Diazo and vesicular films, while often cheaper and faster to produce for duplication, typically have shorter archival lifespans and are not preferred for primary archival masters.
A 'master negative' in microform duplication is intended for direct user viewing and is only replaced if damaged.
Answer: False
The master negative in microform duplication is preserved for the sole purpose of creating duplicate negatives, thereby safeguarding the original master from wear and tear. It is not intended for direct user viewing.
Properly processed silver halide microfilm on an acetate base has an archival life expectancy of approximately 50 years.

Silver halide film is generally cheaper and faster to produce than diazo film for microforms.
Answer: False
Diazo film is typically more economical and quicker to produce than silver halide film, making it suitable for duplicates. Silver halide is generally preferred for archival masters due to its superior stability and quality, despite potentially higher costs and processing times.
Color microform is less common partly because older color dyes could fade over time.
Answer: True
The reduced prevalence of color microform can be attributed, in part, to the historical tendency of older color dyes to fade over extended periods, compromising the long-term integrity of the recorded information.
Redox blemishes on microfilm are characterized by:
Answer: Small, yellow/orange/red spots caused by oxidation.
Redox blemishes manifest as small, typically yellow, orange, or red spots resulting from the oxidative degradation of the microfilm's surface.
Why are diazo and vesicular films often used for duplicating microforms instead of archival masters?
Answer: They are significantly cheaper and easier to produce.
Diazo and vesicular films are frequently employed for creating duplicate microforms due to their lower production costs and faster processing times compared to silver halide, making them suitable for distribution rather than primary archival storage.
What is the purpose of creating a 'master negative' in microform duplication?
Answer: To be used only for creating duplicate negatives, preserving the master.
The master negative is maintained solely for the generation of duplicate negatives, thereby protecting the original master from wear and ensuring the long-term preservation of the archival record.
What is the archival life expectancy of properly processed and stored silver halide microfilm?
Answer: Approximately 500 years
When processed and stored under archival conditions, silver halide microfilm exhibits an estimated life expectancy of approximately 500 years.
