Acronyms--How often do you spell them out?

[Darges, Katherine]

All,

 

I am editing a multi-section document, with each section 50 to 75 pages.
The document was written by the Government for the Government.  Phrases
that get turned into acronyms are spelled out when they are first used,
followed by their acronyms in parentheses - most in the first section.
Appendix A is a complete acronym list - about 300 all together (this IS
the Government, after all).  

 

Would you re-identify the acronyms in each subsequent section as well as
adding the new ones?  Or, is once really enough, based on the fact that
the readers of the document have all been involved in the project of
which the document is a record?

 

Thanks!

 

V/r (that's "Very respectfully" in Government shorthand),

 

Katherine
