Help in writing papers.
Suppose you are writing a paper and need to refer to Hobby and
McKenzie's book on tame congruence theory. You should do a search
by entering Hobby McKenzie in the author field.
From this you will see that the identification key is
HobbyMcKenzie1988. In your latex file you use the command
\cite{HobbyMcKenzie1988}. You should also make a bib
file and put the whole entry in it. You can do this with cut and
paste.
If your paper will refer to say several papers by Kearnes you can just
enter Kearnes in the author field and then save the resulting
output to a file. This file will have a few lines of html code at
the beginning and end. After you delete these you will have a valid
BibTeX file.
