Abstract

The subject matter of this disclosure relates to an improve~ ment to the ways of searching a reel of microfilm in a reader~printerfor text pages which relate to subjects of interest to the user, The concept is best described by an illustrative example as follows: First, a subject keyword analysis must be done and up to 36 terms can be distinguished in this system, Assume that there are up to 2,000 text pages on a reel of microfilm, At the front of the reel will be up to 36 extra frames, each one devoted to a subject or keyword. Each frame is divided into 2,000 places on a 5° to the inch pitch using 8" x 10" of the equivalent full size area, Frame No, 1 will relate to keyword No. 1, The frame is composed of short vertical strokes, each stroke indicating that the keyword does apply to the document associated with that place in the 2,000 place matrix, Keyword No, 2 is on frame No, 2 and uses strokes inclined at 5° to the vertical, Sim-' ilarly, each successive keyword would use a stroke 5° away from the previous one, By the use of a special mode in the viewer/printer, a single sheet of paper is used to receive imprints from every keyword frame selected by the operator. Therefore, an operator would select, for example, frames 2, 5, 9, 16, and 17, Each frame would be lined up when se- lected in the viewer, and a special print key pressed, when all five frames have been exposed in this way, another key would release the sheet of paper which would contain the superimposed images of all five frames,

The subject matter of this disclosure relates to an improve~
ment to the ways of searching a reel of microfilm in a
reader~printerfor text pages which relate to subjects of
interest to the user, The concept is best described by an
illustrative example as follows: First, a subject keyword

analysis must be done and up to 36 terms can be distinguished
in this system, Assume that there are up to 2,000 text pages
on a reel of microfilm, At the front of the reel will be up
to 36 extra frames, each one devoted to a subject or keyword.
Each frame is divided into 2,000 places on a 5° to the inch
pitch using 8" x 10" of the equivalent full size area, Frame
No, 1 will relate to keyword No. 1, The frame is composed
of short vertical strokes, each stroke indicating that the
keyword does apply to the document associated with that
place in the 2,000 place matrix, Keyword No, 2 is on frame
No, 2 and uses strokes inclined at 5° to the vertical, Sim-'
ilarly, each successive keyword would use a stroke away
from the previous one, By the use of a special mode in the
viewer/printer, a single sheet of paper is used to receive
imprints from every keyword frame selected by the operator.
Therefore, an operator would select, for example, frames 2,
5, 9, 16, and 17, Each frame would be lined up when se-
