Help for Desiderata
Online catalogue (IPAC) help.
Page Desiderata offers an option to fill in and send a form with the request for buying a document that library does not have nowadays but you are really interested in it.
A detailed document description will help librarians to find and identify the document. Information about you as a user is sent off with a request form, so a librarian can write to you and inform you about your request processing.
