Copyright Policy

All the text and pictures on this Web server are copyright 1997-2017 by the authors, photographers, and/or

Here are the terms of our blanket license...

Printing of photos for personal use

If you want a copy of one of our pictures to stick on your fridge or use in a school project or cover a crack in your wall, then please feel free to print anything you like from this site.

Non-commercial Web use of photos/writing

If you have a personal home page or non-commercial Web service, please feel free to link to or embed our photographs with hyperlinked credit. Acceptable HTML is
courtesy <a href=""></a>
That way people know where the contribution originated and also can find this on-line copyright statement. If you would like to rehost any material, permission must be obtained from the copyright holder.

Commercial Web use of photos

If you would like to use our writing or pictures on a commercial page, then please do the following:
  1. register the URL with us (sending email is fine)
  2. add the hyperlinked credit as above
  3. link to the original photo
You do not need to pay for usage, either, though we reserve the right to deny usage on sites that we dislike. (Anyone can still link to anything they want however)

Note: remember that most of the pictures of people on these pages are not model-released. Advertising usage of photos (e.g., brochures, catalogs, print ads) is very different from editorial usage of photos (e.g., newspaper and magazine articles, books). You cannot use pictures in advertising (e.g., an on-line product brochure or anything else that is selling) without getting a model release from any person whose image is recognizable in the photo. You might also have problems if an image contains a recognizable physical property, e.g., Disneyland. One of the reasons advertisers pay $1000+ for images from stock agencies is that those agencies have generally already gotten the relevant releases.

Text and Stories

Please feel free to redistribute via hardcopy or email for noncommercial purposes any of our writings, but please don't break up documents (except by chapter) and please attribute the source in such a way that someone can find the most up-to-date version on the Web.

Please do not ever copy any of our (text) content to a public Web server. Link to our pages instead. We will endeavor not to break any of your links. The problem with you putting a page on your server is that the search engines will find it and send our readers to your server instead. Thus readers will be deprived of our latest content and service innovations.

Use of photos and Web pages in print

If you are doing a story, book, or CD-ROM about the World Wide Web, please feel free to include a page or two of our under the following conditions:
  1. screen captures must be made from a computer with a 24-bit color video board. (Machines with 8-bit cards produce distorted images and colors.)
  2. the URL must be legible in the capture or separately printed in a caption
