I knew the ISOGEOCHEM subscribers wouldn't let me down. Thank you for 
your quick and helpful response.

My problem was (and still is) that someone borrowed my CRC handbook 
and forgot to hand in back. I am the only guy in this department who 
has a copy of the CRC.

As to our library service, well, let's pass over it in silence. I 
needed the information rather urgently.


Thank you very much again,
