Hi all,

I have noticed that a lot of my searches turn up links to PDF files which are
really not there. These are hosted at reputable insitutions, like ieee.org,
elsevier etc. I find that I waste quite some time bothering to look at the links
(wrongly believing that they contain what Google says they contain). Example:

  http://linkinghub.elsevier.com/retrieve/pii/S0041624X05000582

Yet, when accessing the link one gets an intro and an invitation to purchase. At
the same time, the Google link has no HTML backup for such pages. I am under the
impression that Google does not allow such tricks, and that one must pay to
allow such use. Am I wrong ? If I am wrong, how does one go about achieving such
excellent free advertising for one's pay products ?

thanks,
Peter P.

Note: The link above was the 1st on page 51 (!!) of the search with key:
 
  http://www.google.com/search?q=piezo+driver+schematic&hl=en&start=50&sa=N

The text found by Google was:

 "A simplified. schematic of the driver stage is shown in Fig. 4. The dri-. ver   
 discharges and charges the piezoelectric disc via. transistors MN1 and MP1, ..."

which is not at all on the page at the link above.
