For Your Information The University of Florida at Gainesville is offering a short course entitled Modern Analytical Chemistry. The course, to be held March 18-22, is designed principally for scientists who have been out of school for 10 or more years and who may have lost touch with recent advances in the field. The course will provide an overview of modern analytical techniques, along with a discussion of "research fronts" in each area. Enrollment will be limited to 60 participants. Tuition, including room and board, is $800. Purchase orders or checks payable to the University of Florida must be submitted by Feb. 1 to Jill Sanderson, Division of Continuing Education, University of Florida, 1938 W. University Ave., Gainesville, Fla. 32603. For more in-
formation, or to indicate your intention to enroll, contact John Dorsey at 904-392-0557. D14-P, "Proposed Guideline for Enzyme and Fluorescence Immunoassays," a new publication from the National Committee for Clinical Laboratory Standards, contains guidelines for enzyme and fluorescence immunoassays of macromolecular analytes. Factors that contribute to reliable and reproducible results are emphasized in sections that describe choosing enzyme fluorescence systems, producing, processing, purifying, and characterizing antibodies and antigens, as well as reagent separation techniques and instrumentation and equipment. Copies are $15 each (plus $1 additional for orders outside the U.S.); discounts are available for multiple copies. For more information contact the National Committee for Clinical Laboratory Standards, 771 E. Lancaster Ave., Villanova, Pa. 19085. CAS Document Delivery Service provides copies of documents abstracted in Chemical Abstracts, CA Selects, and CA Section Groupings, documents summarized in Chemical
Industry Notes, and documents cited in Chemical Titles. If the service cannot provide a photocopy of the desired document because the copyright status is unclear or because it does not have the publisher's permission to copy, the service will loan you the document from the CAS library. The cost of a photocopy or document loan is $12 if the CA number is provided and $14 without the CA number. For more information contact Chemical Abstracts Service, Customer Service— DDR, P.O.
