FILING INSTRUCTIONS FOR THIS TEMPORARY REVISION
For paper publications:
File this cover sheet behind the publication's title page to identify the inclusion of the Temporary
Revision into the manual. Insert the new pages into the publication at the appropriate
location(s) and remove and discard the superseded pages.
For aerofiche publications:
Draw a line through any aerofiche frame (page) affected by the Temporary Revision with a
permanent red ink marker. This will be a visual identifier that the information in the frame (page
is no longer valid and the Temporary Revision should be referenced. For 'Added' pages in a
Temporary Revision, draw a vertical line between, the applicable frames wide enough to show
on the edges of the pages. Temporary Revisions should be collected and maintained in a
notebook near the aerofiche library for quick reference.
