The t i t l e of this t a l k reminds m e of t h e o l d c l i c h e '%Ben d i d you s t o p

If you claim that t h e surgeon cannot keep up r i t h t h e
growth of knowledge, then you are merely r e p e a t i n g a truism--a
s t a t e of

If you claim that t h e surgeon can keep up. then you are deny-
l u g , by implication, t h a t t h e problem is serious.
Undoubtedly t h e problem of s c i e n t i f i c information i s a s e r i o u s one.
Most
of you have suffered from t h a t special bibliographic d i s e a s e c a l l e d "piles"-p i l e s of j o u r n a l s that is.
Almost every week I v i s i t a medical colleague who
has s t a c k s of unread j o u r n a l s on his o f f i c e c h a i r s o r tables.
A f e w who can
a f f o r d t h e luxury of storage space and cost of shelving have (bound) volumes
of hundreds of books and j o u r n a l s that have never been cracked.
But don't you f i n d i t s t r a n g e , i n t h i s age w h e r e information abounds plent i f u l l y , t h a t whenever you want t o knoar sanething. you c a n ' t f i n d it?; o r

whenever you want t o f i n d t h a t a r t i c l e you once r e a d , you can't remember e x a c t l y
where?; o r somehow you missed an a r t i c l e only t o have one of your f r i e n d s t e l l
you about i t a year t o o l a t e ?
This f e e l i n g , o r s i t u a t i o n , which I have described
elsewhere a s bibliographic poverty i n t h e midst of information plenty ( l ) , is
not an i s o l a t e d one.

However, I hope I can give you cause t o f e e l that t h e s i t u a t i o n is not comp l e t e l y a s bad a s w e f e e l o r a r e sometimes l e d t o believe.
Nevertheless,

Of these, in my opinion,

But even assuming t h a t a l l 2,500 a r e of value t o someone, somewhere-these j o u r n a l s only account f o r about 150,000 medical papers per year.

Since the SCI is so g e n e r a l l y a v a i l a b l e , I w i l l not spend t i m e during
my t a l k in d i s c u s s i n g i t s use but would g l a d l y answer q u e s t i o n s about it in t h e
discussion period.
The ASCA system is p r i m a r i l y but not e x c l u s i v e l y based on t h e concept of
c i t a t i o n indexing.
Unlike conventional word indexing systems, in ASCA w e c a n
also a s s o c i a t e p e r t i n e n t s u b j e c t matter through c i t a t i o n l i n k s .

It is that simple.
You can read t h e ASCA brochure

There are two major s o c i o l o g i c a l problems that stand i n the way of t h e surgeon keeping up w i t h s c i e n t i f i c information.
