Dear Madam
It is very useful information what u gave, thank you
dear Mala,
there is some typographical error in some places that i think
1. PRECIS, 1968 development period & 1974 is the date of use in BNB, later replaced by COMPAS then by LCSHs.
2. POPSI, 1979 from Chain Indexing of Dr. Ranganathan.
please you also check and communicate, if i am wrong.
Dear Arshad Ali sir,
BNB adopted PRECIS for preparing subject index since 1971.There is a vast difference between the term "developing "and "developed"(for eg: India is a "developing" country, USA is a" developed "country.)Hence,PRECIS development period was 1971-73 and was developed in 1974.
POPSI, I think 1964 is correct.
