"Both"?  I'm aware of at least three (FreeBSD, 4.3BSD, and 4.4BSD) that
are probably within the realm of what you're talking about (learning
about the workings of a BSD Unix system), all of which seem a little
redundant -- just different editions of the same book, from the look of
it.  What do you mean by "both" of McKusick's books?

I think there's an answer book for at least one of those, too.  Do you
perhaps mean the main book and the answer book?  Do you mean to include
the general-purpose "open source" book as one of the books (Open Sources:
Voices from the Open Source Revolution)?

If you have a decent ebook reader, I recommend just getting on the
O'Reilly mailing list for its periodic announcements of ebook discount
deals and picking up an occasional good book from those deals.  It's easy
to get far more excellent books than you have time to read that way, for
really good prices.  In fact, O'Reilly has a 50% off deal for a few
ebooks about C programming right now:


O'Reilly's ebook deals are about the only way I've found to get good
technical books from a major publisher in digital formats at a reasonable
price, considering most of the publishing world still thinks it's okay to
charge more for ebooks than for hardcopy books for some asinine reason.

O'Reilly is, in fact, pretty far ahead of competitors on its handling of
ebooks.  For instance, if you have a hardcopy O'Reilly book, you can
register it by ISBN with O'Reilly, then get an ebook copy of it for about
five bucks.  By contrast, The Pragmatic Bookshelf (which produces very
high quality books as well) at *best* gives you the opportunity to get a
hardcopy book plus a PDF book at the same time for about 150% of the
cover price of the hardcopy alone, *only* if you buy them together from
the Pragmatic website itself, and if you only have the ebook or the
hardcopy book you have no way to get a discount on the other; you have to
pay full price.  Pragmatic does offer ebooks at slightly lower price than
hardcopy, which is at least better than the "standard" industry practice
for science fiction, but it's a ridiculous price for a bundle of bits in
a digital file.

O'Reilly offers some kind of discount on hardcopies for people who have
the ebooks, too, I think.  I'm not sure -- I've never taken advantage of
that discount, because I only started collecting ebook copies of O'Reilly
books after getting an e-ink reader, which I find every bit as good for
many (though not all) reading purposes as a physical dead tree format
book.  Your mileage may vary, I suppose.
