But it is a LOT of work, especially if you try to keep the formatting something reasonable (tables, titles, headings and bold type all tend to get lost) and then proofreading is a pain as well.   I've already spent far more time on this than it is worth to me, especially since I'm giving away the result for free and hard drive prices are down to somewhere around 4 _cents_ per gigabyte.

I will attest that the size can be controlled, but only with 
considerable massaging.  In the case of the bulletins I published, each 
was individually republished on a template with all the bitmaps replaced 
by vectors (except for the technical drawings, and even those were 
individually reduced in size by erasing accumulated black areas created 
by repeated photocopying and using just one bit per pixel instead of 
grayscale), and all the bitmapped text was converted by OCR and then 
pasted into the documents, then converted to an Interleaf font close to 
the original, or inserted by hand if it didn't convert well.  All that 
required the manipulation of four documents per bulletin--the primary 
scan, the OCR version, the one based on one of several templates and the 
converted PDF.   But, it made the entire collection searchable and kept 
the size manageable (~ 20-25K per page).  A big pain in the ass to do, 
though.


Cheers.
