What do you knowf about chemistry?

...in Ceylon... in the Ukraine... in Zambia ? Ceylon, the Ukraine, Zambia—an Asiatic

island-country, a Soviet Socialist Repub­lic, a newly emerging African nation. What have they in common? All are areas of the world in which important, pertinent chem­ical research is conducted — research you need to know. The way to make sure you do know is to subscribe to the Chemical Abstracts Service Information System.

For over six decades Chemical Abstracts Service has abstracted and indexed all of the world's published chemical literature regardless of where it originated, and we have always made it available to all who need it, by publishing it in CHEMICAL ABSTRACTS.

But today we go further. In creating the Chemical Abstracts Service Information System, we have developed a group of re­lated services that vary in subject, depth

of coverage, currency and distribution media. The System is designed to do one thing — to satisfy YOUR chemical informa­tion needs. There are services that alert you to articles that will be abstracted in CHEMICAL ABSTRACTS. There are others that cover specific portions of chemistry, such as the polymer and biochemical fields. In addition to the printed form, many of our services are available on micro­film or computer-readable tape.

So when you need to know about chem­istry conducted in Ceylon, in the Ukraine, in Zambia, or anywhere else, you need the Chemical Abstracts Service Information System. Write us for more information at: Chemical Abstracts Service, Dept. 13A-K, The Ohio State University, Columbus, Ohio 43210, U.S.A.
