The general experience in Germany seems to be that patrons do have a
few initial difficulties but these are usually overcome within a very
short time. After that, every unnecessary step in the use of the OPAC
is considered a nuisance. Having a menu appear and a choice to be
made from it EVERY time the OPAC is called, instead of just typing in
one's search term and be done with it, is quickly found a distracting
detour. After all, what patrons want is not the catalog but the
media, and the less effort it is to use the catalog the better.

This comes up when you press F1 or '?', and only then - because after
some very short time you no longer need the extra lines at the
bottom, they just take up space which is better made available for
index and record display.

That's up to you, of course.

> F8: Show short title F10: END
> ESC: Restart - more information
This, and some more important demands, must be dealt with in the not
so distant future. Heinrich Allers earlier today mentioned the
deficiency in boolean searching, a very important topic. All of this
is taken very seriously, but we must take one step at a time, and
there's always much more on the agenda than just the APAC program.

You probably haven't yet seen the "bolero" documentation and demo
database. (You can telnet to 184.108.40.206, username "opac", password
"opac", then enter command "bolero") There are authority records for
composers, and in the title records you just enter the composer's
identifier, like #52 _m instead of #52 Mozart, Wolfgang Amadeus.
I happen to believe that the "bolero" method of dealing with
authorities is among the best possible methods and generates very

This is only just beginning in Germany, and none of the current
users, to my knowledge, have e-mail yet.

There's the #30m field for musical classification codes. You can enter
#30m 4+symf: V1 H3 <Sopr1 Fagot1 Hobo2>
and you get all of these elements entered into index 7.
It is possible that some (very little) extra documentation, carefully
thought out, in combination with translations of H10, H11, and
UIFA, will be all you need to make the "allegro" or "bolero"
OPAC popular with your patrons. To set up a sophisticated database
meeting all special musical requirements is a daunting task, whatever
the system's name may be. There's room for improvement, even with the
"allegro" kernel components, but I think we've come a long way.
Hope this helps,
