If its for a meeting then a local copy on the hard drive of a laptop would be nice. Otherwise perhaps a copy of several burned to a CD.
I make my own booklets and cd's with my portfolio and services in. However, my main selling points involve a meeting, my laptop and local copies of my sites.
Do you self publish your booklets or do you send it out to a printer?
I do them myself although I do make them as presentable as possible. I have a colour laser jet and I put them in some cheap by nice looking folder/binder things with a transparent front.
It impressed Vauxhall so I don't think people who too much about the portfolio, more the work in it.
I got a version online of just the entry page of each site that I have done. And I also take it on a transparent binder. I also have a color printer with photo quality. I take a screenshot, and print it out. It really impress customers when you are called up for an interview.
I create a lot of intranet sites. Most of them are confidential. I have to print the design because I can't just give them a URL to check it out. I have an eight and half by eleven portfolio I got from an art supply store that has transparent slots for art work. I adjusted the PSDs to get at least 300dpi (most designs I start at this resolution). I then print them out on photo quality paper or get a fiery from the local production shop. It gives a nice tangible prop for interviews.
I also make sure that I have a version online That has links to my Internet work and snapshots of my intranet work. That way when I leave that can take some more time thinking about my designs.
I also create cd roms to give employers/clients. They come in handy if you get access to a projector during a meeting. It also lets you not have to count on an Internet connection.
I have found that the print portfolio goes over very well. It allows people to pass around work in a more meeting environment. It is more comfortable than crowding around a computer.
I've always had the opportunity to email a few URLs to my prospective employer or client before our first meeting... Then, at the meeting, I can concentrate 100% on discussing their project.
The intranet issue isn't one I've had to deal with... but the alternate is sites that go dead, or get overhauled by someone else after you build them. I keep backups of all my HTML & image source files, so I can put a "duplicate" site up on my portfolio site if need be. (And someday, if I ever update my portfolio site, that's exactly what I'll do... heheh)
I've created one-page color printouts of selected home pages... If they scroll off a standard screen, I do a screen capture of the top, and then of the lower section. I paste 'em into Word, use the crop features to get rid of the scroll bar, borders, and any overlapping content. Now I've got just a couple of images (forming one large image) properly sized for printing - I can then add text like the URL, contact info, or any comments like, "Named one of the top 5 widget sites by...". I've had some clients use these one-page printouts as customer handouts of their own...
