“Condition of microfilm” field – appropriate terms

Terms that can be entered into the “Condition of Microfilm” field in the database are in BOLD

Issues with the surface of the film

abrasion = damage to the surface of the film caused by rubbing, scratching, etc.

crystals on the surface of the film or the roll

fingerprints

mold: bring to the attention of Deb, Sarah, or Sheila immediately!

moisture spots

damage from a rubber band or metal objects, including specifically rust

paper adhering

brittle tape or yellowed tape – if you acted to improve this issue, please add “-new splicing tape applied


Issues with the emulsion layer (the one containing the image)

mirroring = usually bluish-metallic sheen, sometimes has an iridescent quality; in extreme cases, can appear bronze-colored

redox (reduction-oxidation reaction, aka microspots) = red or colored blemishes on film, resemble measles

with regard to image decay, please make a note if you think you see any of the following:

color bleed

color fading

image discoloration = usually yellowing of the image itself (but not apparently of the film base)


Issues with the base layer or the physical condition of the film as a whole

brittle

flaking = localized separation between the base and emulsion layers, usually along the edges

bubbling = “bubbles” appear between the layers

buckling = base clearly separating from the emulsion layer in several places

channeling = extreme form of buckling where the base has separated significantly from the emulsion layer and the film is very warped and brittle

warped = badly out of shape, perhaps bent from handling, but layers are not significantly separating

curling (width) or curling (length)

film torn – if you repaired this problem, please add “-repaired with splicing tape
