I still maintain a business card holder - not quite a rolodex, but I don’t really need every business contact in my Outlook contacts, which is where I keep the rest of them.
Plus, sometimes it’s a PITA to copy all of that information into your Outlook contacts when you maybe only use them once or twice a year.
My blackberry, which syncs with my MS Outlook several times an hour. Also, many people now send out virtual business cards attached to thier emails, so there is no need to retype things.
Google. My Gmail contacts (both personal and my Google Apps account at work) are available to me anywhere, and sync immediately and automatically to my Android phone where they are available at any time and place. For each user it stores names, addresses, several phone numbers, several email addresses, their picture (if they use a photo for their Google or Facebook profile), and any other notes I want to put in their contact “card.” I can even scan a business card with my phone camera and have all of its information OCR’d and entered into my contact list automatically. Way better than a rolodex.
If I get a business card, it goes into the rolodex. If I email someone or call them more than a couple of times, they end up in my Outlook contacts list. There are a number of business contacts that I’ve made, where it isn’t worth the time and effort to transfer the info into Outlook, but I want to have it around someplace.
And I went to the bank yesterday and had to speak to one of the branch reps and noticed she had a GIANT rolodex on her desk, old-style. So they’re still around.
In sales and marketing, people might use customer-relationship management software, like GoldMine or Salesforce.com. These programs usually include a feature to let you store contact info, and also help with managing communications with the prospects.
I have seen a lot of these. In the last few offices I worked at I have set them up for people. The manager usually keeps an online record and then throws the business card into some sort of file system as well
