Neil,
You could use a sharp knife to cut through the spine of each magazine (so
that you now just have a stack of pages), put the whole stack into a page
feed scanner, let it go to town, and then write some software to rearrange
to pages into proper order. It seems like they can do about 50 pages at once
generally, so you'd still have to feed it fairly frequently, but it's better
than using a flat bed scanner at least.
Cheers,
- Marcel

Today I photographed 100 or so pages from up to 100+ year
old documents in a historical archive.
Tripod on library table.
Minolta 7D DSLR.
Std kit zoom lens - not what I'd usually choose (no choice)
but worked fine.
Room fluro lighting.
Adjust colour balance to suit.
400 ISO f16 shutter speed as required.
Typically 1/2 to 1/10 second.
Results excellent - old photos seem about as good as the
originals.

f16 chosen to allow some margin in depth of focus on curved
book pages etc.

Results were good enough that with a better lighting setup
I'd consider this well up to good enough for A4 or a bit
larger magazine page copying.

I'm thinking that might be a management nightmare, and IIRC articles are
broken up all over the magazine, with some small snippets on pages that are
mostly ads.  I don't mind keeping the ads, but I'm not sure how much space
I'd save this way.

What I'd really like is one of those vacuum bag systems for clothes that we
see on TV -- the ones that take a stack of clothes a few feet tall and suck
it down to a few inches tall after the air is removed.  But for magazines :-)

No seriously, I'll have to work out a way to scan these some day.  Maybe if I
do a magazine per week, I'll be done in a few years.

Cheers,
-Neil.

Hope I got the tag right. I need some advice from a friendly Canadian
about mobile phone prepay SIM cards and where to get them from in
Canada.. More than happy to take this off list to email but I need to
find out fairly quickly.

Fido is the only provider around here that uses SIM cards, AFAIK.
Virgin Mobile might, but they aren't anywhere near the marketshare of
Fido.  They are available at 7-11 stores, but you can also find them
on Ebay.

Canada (and probably most of North America) is very backwards when it
comes to cell phones. Thing are much more complicated then they need to
be.

That said, getting a SIM isn't too much more difficult. We have two
providers that run GSM networks (although technically both are owned by
the same company). Rogers and Fido. Walk into either store and ask to
sign up for prepaid. That's right, you have to SIGN UP. They'll ask for
all your personal info and only then will they sell you a SIM and
activate it (this vs. my experience in Europe where buying a SIM was no
more complicated then buying a bag of crisps).

The SIM is $25 last I checked, you'll have to top up with something,
minimum $10.

Of course, the WONDERFUL surprise is that airtime expires here in VERY
short amounts of time. Most cards expire 30 days. Some 60. The odd one
90. The only card that expires after 1 year is the $100 card from
Rogers, but it's often hard to find.

Oh, and just in case you didn't know, almost ANY use of your cell phone
will cost you, that INCLUDES receiving calls. About the only thing that
usually free is receiving texts. And calling long distance to any but a
small number of countries is usually blocked.

That'll be fine. Providing they will register a foreign national of
course.

That's OK, it's for my parents who are leaving to visit relatives later
this week and only staying for three weeks. Roaming charges on their UK
phones are ridiculously expensive, $3 a minute to 'phone the UK and $5 a
minute to phone anywhere else plus $2.40 a minute to receive incoming
calls.

That's dreadful, really?  Does the originator of the call pay as well?

Apologies for all for the continued OT but this is the only forum where
I got a sensible answer, Yay PIClist. Thanks people, I knew someone
would help me here.

There is one other thing to consider, is their UK GSM phone dual or
triple band?

I believe Canada is the same as the US, using 850MHz and 1900MHz.

I have found Vodafone to be cheaper than Virgin in roaming calls -
though that is from an Australia to UK perspective.

Yup, and it depends.

The way cell phones work here is there's no difference to a caller
whether they are calling a landline or cell (in fact there's no easy way
to tell whether a number is a landline or cell, they all use the same
area code), they pay the same rate (local calls from a landline are
unlimited free in most cases).

So, to cover the cost the receiver pays. When a cell phone user calls
any number they pay as well.
