In the following table (4) all NS are included, not only those that returned their completed Biennial Report, to give a full picture of NS participation. The NS which submitted their reports are distinguished by an asterisk (*).
The 2006 IBBY General Assembly was held at the 30thIBBY Congress in Macau, China. 54 NS were represented: 45 directly and by 9 by proxy.
The 2008 IBBY General Assembly was held at the 31 IBBY Congress in Copenhagen, Denmark. 59 NS were represented: 55 directly and 4 by proxy.
The biennial IBBY congress is the main international IBBY activity in which NS participate. However, the financial cost of participating in congresses remains the main reason for absences.
