Reinhard First I must apologise as this will be a brief reply. I'm about to leave for a conference and I will try and give you a more thoughtful reply when I return next week. > >If you don't know my name, I try to maintain a biology subject tree in >Europe.

I have seen these. Any classification is a tree structure. To maintain a set of disjoint classes takes effort. A collection of 10,000 item only need about 500 braches to organise. A collection of 1,000,000 needs 50,000. Such classification scheme require major investments in staffing just to maintain the description of the classification. That is why some schems like the blis schemes have failed and others have continued like UDC and LC. You can BUT the conceptual framework and training courses are available for the staff who are doing the classification. >Also, be realistic on which information to classify. Because of the >difficulty to maintain links (see your own gopher), Seems OK at my end.

I would't be confident of a home grown one. >to average a gopher's content wrt classification. There's where I start >to see problems coming up. Using a published classification the class number determines it's place in a structure. From the class code you know where in the tree to put it. >I'd like to know whether a more obvious classification scheme is around >in librarian's world than Q223 ... > I regret NO classifications are obvious but some come with indexes to the classification. If all else fails you can look up a library catalogue to find the code that is used ;-) Regards Tony ______________________________________________________________________ Tony Barry.
