Query: One the Best Documents on Oracle 8 PL/SQL features

I found "Oracle8 Pl/Sql Programming" to be worth my time and money. Reading the "Oracle8 Pl/Sql Programming" book was like being in the Oracle Education course without paying $2000. Here's why - each chapter has short narrative descriptions of the topics followed by a lab you can do. I like the learn by experimentation approach. Beneficial topics were: Oracle Objects, Collections, DBMS_OUTPUT, TEXT_IO, cursors, and Dynamic cursors. I found "Oracle8 PL/SQL Programming" far superior to the Oracle documentation.
