help in formulae of Gaussian98 rho-ci

Dear Colleagues,
 Would you please to help me sending formulae and short description of
 rho-ci density in Gaussian98. I know that this is described in book
 "Exploring Chemistry with Electronic Structure Methods" chapter 9 but
 I
 have not this book. Maybe this rho-ci is also described in other books or
 articles?
 Please send me these rho-ci description pages by faxes:
 +370-2-225361   or  +370-2-224694
 or by e-mail tamulis[ AT ]itpa.lt
 Thank you very much in advance for this indeed not pleasure work.
