You want to search the ETS database and search for the name of your test.
Find the call number, write that number down and come up to the third floor.
Someone will assist you in locating the microfilm box and determining whether or not we have the test available ( it's kind of strange the database won't tell you.)
Now you can make a copy of the actual test.
Mental Measurements Yearbook will allow you to read a description of the test or search for tests that your subject area. There will also be an interesting abstract of what the test measures.
On some occasions you may find the actual text of the test.
(Tests are proprietary and make money for their designers - they are often hard to get a hold of)
Here's an internet link I found that discusses different kinds of marketing surveys. I think most of this information would be repeated in ETS link above.
