BOPAC

* The usual disclaimer

This is a another brief newsletter to various people that weve been in
touch with on topics related to the BOPAC Project to keep you
informed about progress with BOPAC.  So apologies if you've already
been told some of this news, heard it elsewhere, lost interest, etc...
On the other hand please pass it on to anyone else you think might be
interested.

* Servers 

As more UK libraries offer Z39.50 access we are adding them
whenever we have the information. We now have 25 UK academic libraries
available and a couple of other targets under test.
Suggestions always welcome.
Our 'home' system Bradford has just changed and we havent got
a working link to that re-established yet.

* Changes to the BOPAC System *
-------------------------------

We are making a number of changes to the Java applet which displays
the search results. These include:

- Select by subject option, in addition to the previous options you
can now select groups of records by subject.
*** We would be particularly interested in feedback on this**
We have made the alterations but please be aware this is still
work in progress.

- Showing actual title as well as uniform title in first screen. We hope
this makes the display more informative, for example when a work and its
translations have been clustered together.

- Full record display now includes ISSN and URLs from MARC 856 (not
active links yet).

- The size of the applet and button layout have been changed slightly
(most users shouldnt notice much difference but the system now looks
more uniform across a range of browsers/platforms).



*CCQ

The article on BOPAC mentioned in the previous newsletter is due to appear
in issue 28(2)

*Ariadne

An article  'Practical Clumping'  based on our experiences with BOPAC appears
in Ariadne, 20, June 1999, ISSN 1361-3200, http://www.ariadne.ac.uk/issue20/bopac/

*Guidelines for OPAC Displays
http://www.ifla.org/ifla/VII/s13/guide/opac.htm

This was mentioned in our last newsletter and a copy of Fred Ayres' response
can now be found off the BOPAC Home page at

been told some of this news, heard it elsewhere, lost interest, etc...
On the other hand please pass it on to anyone else you think might be

* New Servers Added

We have added quite a number of new Z39.50 servers to those available
on BOPAC. Notably we have branched out from just having library
catalogues and now offer Medline as well as two databases from the
Cairns project.  Most of the new servers are UK ones. Some of these
come from the listing at UKOLN

http://www.ukoln.ac.uk/dlis/zdir/

and others from personal contacts. Weve added the servers for two of
the UK's JISC funded clumps projects, Riding and Cairns. These are added
into our full set and also available with their own entry points below

http://www.bopac2.comp.brad.ac.uk/~bopac2/htdocs/evaluate.shtml

We are in the process of checking and testing the searches supported by
the various servers so let us know of any problems or inconsistancies.
Two of the Cairns servers, BUBL and CATRIONA, are not well served by
the current system we admit since they are databases of internet
resources and the record display doesnt include URLs at present. The
full records can be seen by using F2 for the MARC display however.

*Netscape

Some versions of Netscape seem to have problems with our Java applet.
Version 4.07 on some Unix platforms can have problems loading large
retrievals, this seems to have gone with 4.5 on Unix but that version
may have font problems in some cases.

*CCQ
An article on BOPAC is due to appear in Cataloging & Classification Quarterly
early this year.

*Guidelines for OPAC Displays
http://www.ifla.org/ifla/VII/s13/guide/opac.htm

Some of you may have already seen the above IFLA report, currently open
for review.  We will be testing BOPAC on some of the examples in the 
paper.

*Future

Full record display - add URL and make linkable and printable


Mick Ridley 05/02/99

July 1998
Numerous breaks in service due to software and hardware changes and electrical work in University.

* BOPAC2

Our BLRIC funding has now come to an end and an account of this work
is now available (see below), we hope to publish a number of articles
in due course on this work. Following the end of the user evaluation
part of the project we have made a few small changes to the system and
are doing some maintenance work.

* BOPAC2 Report

The Project report

                The Bradford OPAC 2 (BOPAC2)
Managing and Displaying Retrievals from a Distributed Search in Z39.50

        British Library Research and Innovation Report 103

is now available, there is a online version at
http://www.bopac2.comp.brad.ac.uk/~bopac2/report/
or as a link from the project home page
http://www.comp.brad.ac.uk/research/database/bopac2.html

* The Future

The system will remain available in its present form and we hope to do
some small amounts of work on it. We are always interested in adding
Z39.50 servers to those available, so please let us know of any that
you think we should add. We are also looking into sources of funding to
continue the work on BOPAC, various possible directions came up in the
course of the project and there are a number of things, some small some
large, that we would like to pursue.

BOPAC2

This is a brief newsletter to various people to keep you informed about
progress with BOPAC2.  So apologies if you've already been told some of
this news, heard it elsewhere, lost interest, etc...

*Project Extension

With many thanks to British Library Research and Innovation Centre we
have a project extension which will allow us to do more evaluation. The
project will now run till the end of Jan 98, although we hope to
continue the work in some form after that time. A number of the items
below follow on from this project extension.

* BOPAC goes Public

To get more user feedback for the evaluation we are now making BOPAC2
more publicly available. The URLs are still the same

http://www.bopac2.comp.brad.ac.uk/~bopac2/htdocs/evaluate.shtml

for the system itself and

http://www.comp.brad.ac.uk/research/database/bopac2.html

for the project home page which now contains a link to the system (so
this is probably the best URL to tell people and please do).
We are also announcing the system on a number of email lists and news
groups.

Allied to this the servers available have been revised. We would still
like comments on the ones available and any other suggestions. Thanks to
the server providers for their cooperation.

To make the evaluation meaningful, the system will be stable and not
change (apart from any necessary bug fixes) till Xmas.  Suggestions for
change are still most welcome and we hope may be implemented in the
future.

* Localized versions

Again linked to getting evaluation feedback we also now have two
localized versions of BOPAC set up for Leeds and Bradford University
Libraries. These have Leeds and Bradford University and BLDSC and LoC
as servers, with the local library set on by default. These are
available as links from each Library's Web pages.  We also have a
special PC set up in Bradford University Library with Netscape set to
point at BOPAC2, with some display material and printed questionnaires
as part of our end user survey. This is partly to provide a Java
enabled browser, to overcome the problem of Windows 3.1 systems.
Thanks to both libraries for their help.

* Online Questionnaire

We now have an online questionnaire, please fill in the Web form and
click the button to send it off to us.
