References

There are three reference systems available; only one, of course, should be used for your contribution. With each system (by author-year, by number only or by letter-number) a reference list containing all citations in the text, should be included at the end of your contribution placing the L^ATEX<#446#><#446#> environment 99 there. For an overall information on that environment see the <#530#>L^ATEX<#447#><#447#> User's Guide Reference Manual<#530#> by Leslie Lamport, p.~73.
