Abstract: A compact record of plural pages of human-readable data from a manual concerning a piece of equipment comprises two opaque sheets in back-to-back relation to each other, each reproducing pages of such data in a reduced size that is readable by a human under normal room light if magnified about ten times, as by a pocket magnifier. The opaque sheets and a marker bearing indicia identifying the piece of equipment are laminated between two substantially transparent layers. The compact record is bound into a booklet, as by a ring, with at least one record of similar construction.
