Bach Bibliography
Service Report

14 March 2011

Due to the power cut in Tokyo, the mirror service from Tokyo is temporarily down. This affects both error report generator and visitor counter, which are  managed at Tokyo server. It is not known when the Tokyo mirror is restored, as the power situation there is uncertain.

12 January 2006

The university is planning another electrical work on Saturday, 14 January 2006, between 1:00pm and 4:00pm GMT. During this period the web + email services will be unavailable. Users are advised to access its mirror servers at either USA or Japan on that day.

7 January 2006

Due to electrical work at the university in the morning of Saturday, 7 January 2006, the service was disrupted from QUB site for nearly a half a day. Email service is also down until Monday 9 January at least. If you have sent me an email today, please resend later next week.

21 August 2003

From 16 to 20 August 2003, there was a technical problem at Queen's University's network and the access to the Bach Bibliography was affected. To avoid frustration and disappointment, frequent visitors are strongly encouraged to keep addresses of mirror sites.

22 November 2002

Two more independent mirror sites have been established: (English) and (Japanese). Frequent visitors are recommended to bookmark them.

2 October 2001

Internet connection to the university was cut off from about 6:00 GMT today without warning. The problem apparently occurred at the infrastructure level outside the university's control, and has now been restored (12:40 pm). I am sorry for any inconvenience caused. Users are always advised to keep the bookmark of a mirror site at Glasgow, which has an independent search engine.

31 August 2001

There was disruption of "search" function from about 14:30 GMT. The problem is now rectified.
ADVANCE WARNING OF SERVICE DISRUPTION. There may be disruption of service from Belfast (incl. Japan and USA) on Thursday 6th September, between 13:00 and 14.00 BST for server maintenance. Glasgow is unaffected.

31 March 2001 [for 9-10 April 2001]

ADVANCE WARNING OF SERVICE DISRUPTION. There will be disruption of service from Belfast on Monday, 9 April 2001, from 07.00 to 14.00 BST for essential maintenance on the central campus router network. This is also followed by the same on SuperJanet network on Tuesday, 10 April, from 07.00 to 09.00 BST. The mirror services from USA and Japan will be unaffected except search facilities and review collections which are retrieved from the servers in UK.

28 March 2001

The Belfast server was down early morning for several hours. I apologize for any inconvenience caused. Please follow my advice below to avoid disappointment.

15 March 2001

Belfast server was down this morning for a few hours, again. I apologize for any inconvenience caused. Please read my advice below.

14 March 2001

Belfast server was down again this morning. The search requests from all the mirror sites to Belfast were equally affected by this. The fully independent service from Glasgow was unaffected, and to avoid any disappointments, please keep at least two bookmarks to the Bach Bibliography (i.e. the one nearest to you and the other Glasgow site).

27 February 2001

For some unknown cause, internet connection between Belfast and the rest of the world was cut off, causing the service being unavailable for many hours. The connection is now restored. The service from Glasgow was apparently unaffected.

19 January 2001

The access to the Bach Bibliography is now counted by NedStat.

3 November 2000

A fully independent mirror service is now established at the Performing Arts Data Service, University of Glasgow (, thanks to the generous help of Mr John McHugh.

18 September 2000

At the International Bach Symposium Utrecht 2000 (12-14 September 2000, organised by Albert Clement), I have outlined my future plan to expand the resource and service in the next three years. We also discussed the future role of the Bach Bibliography, and came up with the following suggestions:

  1. To include the literatures of the Bach Family.

  2. To include information about the work-in-progress (i.e. scholars to know who is doing what at the minute and promote both information exchange and closer co-operation in research)

  3. To streamline the collaborative efforts to maintain the currency and correctness of information provided on-line

Any further views are welcome.
