Hello All,
Some days ago a friend asked me if I knew a good way of sorting UDC
codes. Looking for information, the only thing I could find was:
--------8<--------8<--------8<--------8<--------8<--------8<--------8<
The sort order for UDC is actually very complex since it uses such a
variety of punctuation symbols each of which has a position in the sort
order - and sometimes more than one! Very few database packages have a
special UDC sort order - one being Inmagic / DBTextworks.
One way round this is to replace the punction symbol with a letter
(including one for the plain number with no following punctuation).
Freeman and Atherton in the 1960s used capital letters A to P:
X+Y XAY
X/Y XBY
X XC
X:Y XDY
X[Y] XEY
X=Y XEY
X"Y" XGY
X(Y) XHY
X(=Y) XJY
XABC XKABC
X.00Y XLY
X-Y XMY
X.0Y XNY
X'Y XPY
So if you have a UDC number like 62/64 you write it as 62B64 and you
write 72"1950" as 72G1950. The numbers should then sort correctly.
--------8<--------8<--------8<--------8<--------8<--------8<--------8<

I'm not a librarian, and I do not understand all this rules (like
XABC -> XKABC) Anybody knows where (or if) I can find more information,
or even examples abou the meaning of these rules?
Thanks in advance,
