To add more items to a collection, drag the new files into the
collection in the GLI, then rebuild the collection. To add items to a
classifier, assign the appropriate metadata (eg. dc.Title metadata for
the "titles a-z" classifier) to the files in the collection.

You can read about Greenstone's simple document access mechanism in the
"Formatting and authentication" documented example collection, at
http://www.nzdl.org/cgi-bin/library?a=p&p=about&c=authen-e (there is
even a Russian version of this text).
