! NOTE !
Like most 'LINKS' pages on the web, there will, no doubt, be
more and more dead links on this page over time. It may be
years at a time before I return to this page to remove
dead links and replace some links with better links.
In the meantime, try 'WEB SEARCH links' provided on this page.

You can use an option like 'Find in This Page ...' of your web browser to find keywords on this page, such as 'asteroid' or 'black hole' or 'dna'.

Many 'math-links' have been put on a separate LINKS to math-websites page which includes links to math-news sites, math-blog sites, math-forum sites, math-history sites, etc.

And here is a page of LINKS to math e-documents on the web organized into categories such as Geometry, Number Theory, Algebra, Analysis (Calculus), Applied Math, Numerical Analysis, etc.

As an alternative to the math 'LINKS' pages above, here is a page that offers quick 'direct-access' to math eDocs --- 'in the public domain', mostly PDF files, backed-up (preserved) on this site.

'WEB DIRECTORY' pages on Science/Engineering

< Go to Table of Contents, above. >

< Go to Home page. >

It seems that 'web directories' are dying out. Google and Yahoo closed theirs down around 2014. Then around 2017, the directory from which the Google and Yahoo web-directories were spawned --- the DMOZ 'Open Directory Project' closed down.

It seems that it is just not feasible for a team of people to keep up with all the sites that are going dead and the new sites that appear.

About a year after the dmoz.org site closed down, it appears that a new web-directory site --- curlie.org --- arose from the ashes of 'dmoz.org'. It remains to be seen how long that web-directory lasts.

Following are a few links related to 'web directory' sites.
