Art. 9. The exchange bureaus 

 may, unofficially, serve as mediums 

 between the learned societies of the 

 contracting states for the recep- 

 tion and transmission of the pub- 

 lications of the said societies. 



It shall be understood that on 

 rhese occasions the functions of the 

 exchange bureaus shall be confined 

 to t he free transmission of the works 

 exchanged, and that the bureaus 

 shall in no wise take the initiative 

 in bringing about the establishment 

 of such relations between foreign 

 Parliaments, governmental depart- 

 ments, and learned societies. 



Art. 10. These provisions are ap- 

 plicable to none but documents and 

 works published at or subsequently 

 to the date of this convention. It 

 is nevertheless desirable that the 

 contracting states should endeavor 

 to procure the preceding series or 

 volumes, so that a complete copy 

 of each collection may be in at least 

 one library in each state. 



Art. 11. States that have not 

 taken part in this convention shall 

 have the privilege of adhering 

 thereto whenever they may express 

 a desire to do so. Notice shall be 

 given of such adhesions through 

 diplomatic channels to the Belgian 

 Government, and by that Govern- 

 ment to all the signatory states. 



Art. 12. The convention shall be 

 ratified and the ratifications shall 

 be exchanged at Brussels as soon 

 as possible. It is concluded for ten 

 years, reckoned from the day of the 

 ratification, and it shall continue 

 to exist after that time until one of 

 the Governments shall have de- 

 clared, six months beforehand, that 

 it desires the cessation of its effects.
