FTP (anonymous login) sites:

Programs useful in the analysis of nonlinear data can be found at lyapunov.ucsd.edu which is run by Matt Kennel from the Nonlinear Sciences Institute (NLS) at UCSD (La Jolla, CA): ftp.
Other useful programs are found at saddle.la.asu.edu which is maintained by Eric Kostelich at the Arizona State University. In particular, it contains a program called KLTOOL which does the Karhunen-Loeve (aka, principal component analysis, proper orthogonal decomposition, empirical orthogonal functions) decomposition of one- and two-dimensional time series---at present, it only works on the SGI, though an X-Windows version is said to be in the works: ftp.
DSTOOL from John Guckenheimer is for exploring low dimensional models of flows and maps. It runs on most X-Windows systems and is found at macomb.tn.cornell.edu in the directory pub/dstool, or possibly /pub/other/UT for a more current version: ftp. An older Sun View version called CHAOS can be found at enh.nist.gov: ftp.
Codes for calculating correlation sums are found in ftp.phys-chemie.uni-wuerzburg.de: ftp.
A Nonlinear dynamics biography is available from ftp.uni-mainz.de in pub/chaos/chaosbib: ftp.
GNU software is located at ftp.gnu.ai.mit.edu: ftp.
ACEGR is an X-Windows plotting packing located at amb4.ese.ogi.edu : ftp.
TeXtures is a commercial TeX package for the Macintosh: ftp.bluesky.com : ftp.
MachTen (Mach Kernel UNIX on the MAC) is another commercial product: contributed applications and information are located at ftp.tenon.com: ftp.
MacSciTech provides information on scientific applications of the Macintosh computer: ra.nrl.navy.mil: ftp.
MOSAIC for the Mac is located at ftp.ncsa.uiuc.edu: ftp.
And mac.archive.umich.edu is a general archive for Macintosh software: ftp.
MATHEMATICA related software can be down loaded from mathsource.wri.com: ftp.
Useful Tip: try get file_name - (that's a dash after the file_name) to view a file when using ftp.

GOPHER sites:

Gopher server.
Archive of BTK-MCA software, etc., at Oxford.

TELNET sites:

Library of Congress---great for searching for books on a given topic. A manual for how to search the LOC's database is available from ftp.loc.gov in /pub/LC.Online: ftp. LOC's W3 server.
aip.org for possible jobs (-not-) in physics. "Login:" and "Passwd" are aipjobs.
Netfind: bruno.cs.colorado.edu: telnet.

NEWS Groups:

sci.nonlinear: news.
sci.chaos: news.

Many mathematical libraries are available from NETLIB. Updates and additions are reported in SIAM NEWS. To get a listing of these libraries send mail to netlib.ornl.gov with the message send index.

The Society for Industrial and Applied Mathematicians (SIAM) runs an activity group on dynamical systems. To learn more about it contact dyn@siam.org or dyn-request@siam.org.
