I have a bit of a problem with our headlong rush to put everything in
electronic format without the benefit of print. As time goes along and
irreplaceable resources become more scarce (such as petroleum and coal),
electricity is going to become scarce (well, you don't think them green
party bozo's are going to let nuke power make a comeback, do you). I would
like to think we could still design our PCBs (with tape and knives, of
course) and still have the 'ol print IPC standards to fall back on, even
though there would be no power available to spin up the CDs.
<%^o
We could power the gizmo's we design with solar energy, couldn't we?
Well, if Chris can make bad rhymes, I can go off on a wild tangent.

While it certainly costs less to do discs I for one can vouceh for the fact
that printing (not to mention postage) cost have - and are still - going up.
TTry to think f it as paying for data, not a book.
I remember stories from the 90s about receiving and accounting folks
wondering how a 10" mag tape could be worth $50K - even if it was stete-
of-the-art CAD code. While I consider myself a print kinda guy, I'm looking
for more and more stuff digital. (Natl Geographic has gotta be print. I also
do not do "books on tape - I like hardbacks - it's a preference for which I
pay extra)
Now, the issue with things like standards is the format for you printing and
the issue of reuse or licensing. The digital method of getting it from the
agency only makes sense, unless ya wanna pay EXTRA for print.

Good points Jack...
However, almost every time I have had to look something up, I have been
somewhere away from the computer... Books do not require batteries or an
electrical outlet to read them... and I can Xerox a page if need be...
I wanted to be able to do both, and if the print function was setup to let
you print the book so you could end up with both it might be worth buying
the CD... but as it was, I was much happier with the paper version for my
needs. At least I can carry it with me to the local restaurant and read
while I eat lunch if I need to.
:)
CD's are much cheaper to reproduce than paper books and should be cheaper to
buy if you ask me... but it's hard to fight city hall... something special
about it being electronic makes it cost more... go figure.

on the other side of the coin....
I love having computer versions.
paper sucks.
I can make a bazillion copies, and
why do I need to print them anyway?
I just need the data when I need it.
As a matter of fact, they include a
utility to print a single page at a time
if you really need to show a print to
someone. I never used it, because if
I ever need to show anything I
just use snagit (or any other decent
screen capture utility) to print it.
paper is temporary, data is forever.
just another opinion...
Jack
p.s. I would recommend IPC-2221, 2222
and the land pattern standard. That will
keep you busy enough for awhile.
Here's a free copy of the next 2221, go here
and click the "drafts" link:

Get it quick, they don't stay there forever...
