Legacy Web Server

Professor Kostic's old, legacy Web server is no longer updated and may not work now now.
Sorry for any broken links, redundancies and other inconvenience.

The Legacy Web site was developed as Prof. Kostic's "unedited and redundant messy-notes" for personal use" and later posted as such for public use.

Professor Kostic's NEW Web sites are "mostly unedited cut-and-pastes" from old Legacy Web pages, also with some updates at:

(1) the new NIU site with the same domain name at www.kostic.niu.edu (or www.niu.edu/kostic), and also at 

(2) Google-site (http://Prof.MKostic.com)
