# Availability of LAPACK

The complete LAPACK package or individual routines from LAPACK are freely available on netlib [44] and can be obtained via the World Wide Web or anonymous ftp.

The LAPACK homepage can be accessed on the World Wide Web via the URL address:

> `http://www.netlib.org/lapack/`

Prebuilt LAPACK libraries are available on netlib for a variety of architectures.

> `http://www.netlib.org/lapack/archives/`

The main netlib servers are:

Tennessee, U.S.A. | `http://www.netlib.org/`
New Jersey, U.S.A. | `http://netlib.bell-labs.com/`
Kent, UK | `http://www.mirror.ac.uk/sites/netlib.bell-labs.com/netlib/master/`
Bergen, Norway | `http://www.netlib.no/`

Each of these sites is the master location for some significant part of the netlib collection of software; a distributed replication facility keeps them synchronized nightly.

There are also a number of mirror repositories located around the world, and a list of these sites is maintained on netlib.

Most of the sites provide both ftp and http access. If ftp and http are difficult, a user may wish to send e-mail. E.g.,

> `echo ``send index from lapack'' | mail netlib@www.netlib.org`
