Three off-site links on my web site no longer work because the
sites I've linked to have redeveloped their sites.  I wasn't
able to find new page locations after a few minutes of searching.

For each, I'm giving the URL, title and author and a little info
on what was on the page (or set of pages).  I'd like to know the
new URL if one was found.

It might be an idea to find other sites that linked to them
(by author and article name) to see if they've got updated
URLs.

"Safe web colours for colour-deficient vision" by Christine Rigden
http://innovate.bt.com/people/rigdence/colours/
(Articles and resources concerning colour vision deficiency.  You can
see how the 216 colours look to people with various colour defiencies.)

"A New Look at the 216-Color Palette" by Troy Brophy

(An article about reorganising the 216 palette into hue.  Includes
triangle-shaped palette layouts)

Thanks.


Paola, annoyed that people don't set up redirects

Hello paola!

It would appear that Ms. Rigden's site no longer exists at all. 
Following back to the root directory yielded a "404 File Not Found"
error, and following links from pages linked to the site (11 pages of
Google results in all) gave the same results.

All is not lost, however!  Ms. Rigden's site still exists in the
Internet Archive's Wayback Machine:

"Safe web colours for colour-deficient vision"
http://web.archive.org/web/20020125085054/http://innovate.bt.com/people/rigdence/colours/

Additionally, you might want to drop Ms. Rigden a note to see where
she may have moved (or might be moving) her page.  Her e-mail address
is given on the title page of the article noted above.

Tony Brophy's article has likewise been removed from the ZDNet site -
searching both ZDNet and CNet turned up nothing.  Fifteen hits on
Google yielded the same link you note in your question, so I once
again turned to the Internet Archive's Wayback Machine:

"A New Look at the 216-Color Palette"
http://web.archive.org/web/20020124195831/http://www.zdnet.com/devhead/stories/articles/0,4413,2164527,00.html

Mr. Brophy's e-mail address can be had by clicking on his name,
beneath the title - it should automatically open your e-mail client. 
As with Ms. Rigden's article, you may want to drop him a personal note
and ask where he has the article available (if he does at all - the
article actually belongs to ZDNet, not Mr. Brophy.)

The same is true for Mr. Slaybaugh's article - removed from ZDNet,
property of ZDNet, and currently only available through the Wayback
Machine:

"CSS -- Relative Sizes of Text"
http://web.archive.org/web/20011125062959/http://www.zdnet.com/devhead/stories/articles/0,4413,2140835,00.html


As a side note, if you're concerned about linking to the Internet
Archive pages, rest assured that it is permitted under the TOS for the
Wayback Machine:

Can I link to old pages on the Wayback Machine?  
http://www.archive.org/about/faq-wayback.html#2

I hope these will help you out!  In the future, give the Wayback
Machine a try if someone moves their page!  There's a very good chance
you'll find it there, as long as you have the old URL:

The Wayback Machine
http://www.archive.org

Best regards,
missy-ga


Search strategy:  Google:  Title of each page
                  Internet Archive:  URL of each page

Hi again, paola!

A colleague just sent a direct link to Ms. Rigden's site:

"Safe web colours for colour-deficient vision"

Many thanks to Librarygopher for the tip!

Paola,

Thank you so much for your kind words!  But "much admired"?  One
shouldn't make the Researchers blush!  It's undignified!  Or
something.  ;)  Very sweet of you.

I'm glad you're pleased with your answer!  Librarygopher and Chromie
are terrific, aren't they?

missy

Perfect!  I got updated links, I found out about a resource I didn't know
about and had my answered by the much-admired missy!  Thanks also to
Librarygopher and chromedome - the extra help is very much appreciated.

Hello, Paola.

Mr. Slaybaugh informs me that the chart which was the heart of his
article has been reproduced at this link:
http://www.personal.psu.edu/faculty/j/c/jcf12/xhtml/01winter/FontSize.htm

He commented further that, 

"Being from 1998, it's somewhat obsolete, as Windows 95 and IE4 was
the most advanced platform at the time.

However the main conclusions, which are still relevant, were:
     a) The resolution on macs is typically 30% higher than on
Windows, so font sizes specified in pixels will appear much smaller on
macs, while point sizes are consistent across OSs.
     b) Because Netscape and IE use different math to calculate
irregular point sizes such as 8, 11, 14, 17, and 20 (one rounds up and
the other rounds down), those point sizes appear at different sizes
depending on which browser is used.
 
The trend now, however, is to use relative units (ems or percents) so
that the user is more able to adjust the size of the text himself."

I hope this is helpful.
