The Professional electronic
edition comes as a
personalized high-quality PDF file that can be read, searched,
annotated, and
printed with
Adobe's standard PDF reader.
The
cross-references
in
the
text
are
active
links:
when
a
proof
cites
"Lemma
3.1",
for
example,
click
on
the
"3.1"
to
be
taken
to
that
lemma.
For
each
result
or
proof, there are links in the margin to take
you to the results needed for this proof, or in whose proof the current
result is used.
The Professional edition costs €49.95, the same as the printed book. It
is intended for personal use. You
may keep and use separate copies on all your computers
simultaneously, and print as much of the book and as often as you
like – including the entire book.
If you would like to print handouts for a course you are teaching from
the book, you can get your Department to obtain a licence for that too,
see the link below.
