A s i m i l a r b i b 1 iography has been r e c e n t l y completed by t h e Washington S t a t e Department o f N a t u r a l Resources (1982). The main f u n c t i o n s o f t h i s b i b l i o g r a p h y a r e ( 1 ) t o serve as a research t o o l f o r l a t e r work i n Oregon, and ( 2 ) t o serve as p a r t o f t h e data base f o r t h e S t a t e of Oregon. The l i s t i n g s and a n n o t a t i o n s were d e r i v e d from thorough searches o f t h e f o l 1owing sources : (a) B i b l i o g r a p h i e s o f t h e geology and m i n e r a l resources o f Oregon.
