Opening
Division Director, Teresa Goodman, opened the meeting at 9:00 a.m. and welcomed everyone present. DD expressed her formal thanks to Dr. Sagawa and AIST for hosting the Division meetings and the LED Symposium in Tokyo.

2. Introductions
DD Goodman introduced D2 management team, and relayed special apologies from AD, Guy Vandermeersch and new Editor, Jim Gardner, who were not able to attend this meeting. All the participants introduced themselves.
3. Approval of Agenda
DD proposed adding two items to the agenda of this meeting previously distributed (Attachment 1). DD proposed to add a new item as 7.1 on ILV, and to change item 11.3 to be a discussion on Div.2 website links, including database on optical radiation properties of sources, detectors and materials. The agenda with these changes was approved.
4. Approval of the 2003 D2 meeting minutes
The minutes of the 2003 D2 meeting in San Diego, USA, which were distributed via e-mail circular and on the website in September 2003, were approved with no changes. DD expressed her thanks to Secretary for always preparing very complete and comprehensive minutes.
5. Director’s Report (T. Goodman)
The joint Symposium on LED Light Sources, held this time in Tokyo, was very successful; 94 participants registered for the event, demonstrating the continuing high level of interest in the subject of LEDs. A follow-on symposium on the same subject will be planned in a few years.
John Moore (UK) stepped down as Division Editor at the end of the last quadrennium (2003), and Jim Gardner (CSIRO, Australia) has taken over the position. He has already been working on the ILV and in future all documents (TC reports, etc.) to be published should be sent to him. DD further recommends that TCCs send their draft documents to the Editor when they are near completion and certainly before TC ballot.
DD reported a few issues from the Board meeting held after the San Diego session in 2003:
a) New policies and procedures for publication sales
These were agreed by CIE BA and have already been introduced. CIE publications can now be purchased directly from CIE CB as well as from NCs. The prices are the same whether ordered from CIE CB or any NC. Arrangements have been made so that the income from the sales (when ordered from CIE CB) are credited to each NC depending on which country each order came from. DD encourages everyone to order from CIE CB, which is both quicker and less trouble for CIE (no shipping to NC). It is also planned that publication sales will shortly be possible directly via a website and optimum methods for this are being investigated. DD asked whether anybody had purchased publications recently in the new way. Ohno reported his experience that the ordering process was very smooth and publications were delivered from CB very fast (in one week). Kohmoto experienced the same in Japan. Several people mentioned that it is additional advantage that credit card payment is accepted. Rattunde indicated that he has an arrangement with the German NC so that when new documents come out, these are sent to him automatically. DD suggested that such an arrangement might be made with the CIE CB (at least, to notify people when new publications are issued). She will suggest this at the next CIE BA meeting. Gibbs mentioned some difficulties associated with the CD ROM of all current publications and the very high on-going costs for this. DD will raise this as well at the next CIE BA meeting.
Johnson suggested that it would also be useful to have the list of current publications and abstracts (with prices and ordering information) available for electronic distribution. There are already some pages on CIE website containing this information, but there is a need to make it more easily available. It was agreed that Secretary will post, on D2 website, an announcement of the new method for ordering publications that is now in place. DD also added that NC members have large discounts on prices of publications, which is one of the big benefits of being a NC member. Bergman (President of CIE-USA) suggested that it might be a good opportunity to invite new membership when orders come from a non-member. For example, an invitation to join the appropriate NC could be sent together with the ordered publications or, when the website for direct ordering of publications is available, this could be linked to the membership application page of the relevant NC website. DD agreed this is a good idea and will suggest it at the next CIE BA meeting. It was noted that the fees for NC membership are still different and are at the discretion of each NC. The fees cannot be harmonized due to the different ways and budgets under which different NCs operate.
b) CIE Handbooks
Johnson asked about the new form of publication that had been discussed at previous meetings, namely compilations of CIE publications on given topics (‘CIE Handbooks’). DD said that there has been no progress on this, due mainly to the costs involved in binding the publications in book form. Johnson pointed out that technology is available for publishing books in small quantities at low cost and suggested CIE should investigate this further. DD will raise this at the next CIE BA meeting.
