          REFERENCES FOR LEAST SQUARES METHODS

			{\AA}ke Bj{\"o}rck

This is the BibTeX reference base which I have used for the book
Numerical Methods for Least Squares, SIAM, 1996 (reference {bjor:96}).
It is available by anonymous ftp at

          math.liu.se

in the directory

          pub/references

It has been modeled after the BibTeX reference base of Pete Stewart, and
the same comments applies to its use. Below I repeat some of the introductory
comments of his base:

CITATION KEYS

A citation key is divided into two fields, <authors>:<date>, separated
by a colon.  The author field is constructed as follows.  If there is
only one author, the first four letters of his or her last name are
used to form the field (but only one letter each from prefixes, e.g.
van de Geign becomes vdge).  If there are two authors the first two
letters in their last names are used.  If there are three authors the
first two letters of the first are used with one letter from each of
the second and third.  If their are four, one letter from each is used.
Warning:  there may be a few exceptions to these conventions.

NAMES

Names appear in the order in which they appear in the reference, and entries
are alphabetized by the first name to appear.  To keep BibTeX from
becoming confused, only initials of given names are used.

Between some entries you will find clusters of two letters--e.g.  -ac- -ad-.  
These can be used to position yourself within the reference base.

KEYWORDS

Each entry has a keyword field, labeled kwds.  The program bibsrch (see below) 
will search the file for matches in a user-specified
combination of conjunctions, disjunctions, and negations.  The user
can also specify the author.  The program getkey dumps the keywords
on the standard output.  To get an alphabetized list of all key words
from the file ref.bib try

          getkey ref | sort -uf > keywords

The choice of key words is a highly personal matter. I have used a number 
of abbreviations to keep the kwds field to a manageable size.  Here they are.

appropriate places.  (They are actually key words in the last article
of the base; take a look.)

DISCLAIMERS

 Do not use the references in a paper, unless you have checked them out 
for yourself.  Naturally, I am interested in hearing about any errors 
you may find. This reference base downdated regularly, and items can 
disappear.  For example, I will generally remove techreports as I find them 
published in journals.  If you use this base in a \bibliograpy command, 
save your bbl files!

BIBSRCH

The programs bibsrch and getkey, written by G.W. Stewart, may be generated from 
the file bibsearch.tar, available by anonymous ftp at

          thales.cs.umd.edu

in the directory

          pub/references.

Simply place bibsearch.tar in the directory where you want the directory
containing the programs.  Then

          tar xf bibsearch.tar
          cd bibsearch
          more README

and you will be told what to do next.
