Arthur's comment reminds of a guy I met recently who "doesn't carry business cards." I understand the point that almost all the time almost anything you hand out will end up in the garbage.
It is also true that it's a numbers game. You never know for sure where that card will end up, who needs it or how the person you hand it to will put it to use.
Even more to my point though is that the card makes it easy for the other person to take actions favorable to your interests (and theirs hopefully).
A business card is a place to write pertinent info reminding the other person of why they have your card. It gives all the info they need to contact you again and follow up and hopefully refers them to other info (your web site). (Obviously this may not all be true: some people have cards you can't write on either because they are full of text and graphics or because they are glossy. And some people have cards that fail to include critical contact info - I don't know why.)
A business card can be a lot of things. Different for each of us according to our needs and the needs of our clients/customers/patients. For many folks the card itself is suppose to generate massive emotional impressions about how wonderful they are - that's fine, especially if they can back the impression with equally impressive other stuff: whatever that may be, I'm thinking office, website, location, whatever. The card is part of a system.
The question was about pamphlets or brochures. So it's really about the thought process about and creativity around creating that material: the graphics and text, organization and so forth. I personally think the reason most paperwork ends up in the garbage is that most of it is of such poor quality.
Lastly, just because you have a card or a brochure doesn't mean they get one. Whatever you have, it isn't for everybody so qualify them. (Arthur's point I think.)
