To determine the availability of a test or instrument via a publisher, two good print sources are the following:
- ETS Test Collection Catalog (Series)
Ellis Library Reference REF LB 3051 .E79
Ellis Library Reference REF BF 176 .T43
Additional print sources are listed under the heading General Sources of this guide. The Internet can also yield publisher information by use of a search engine, e.g., Google . Keying in the publisher name is the best and most direct approach; however, one can determine the publisher indirectly by use of the test/instrument name as a key concept.
