The University of Kansas Science Bulletin (continuation of the Kansas University Quarterly) is an outlet for scholarly scientific investigations carried out at the University of Kansas or by University faculty and students. Since its inception, volumes of the Bulletin have been variously issued as single bound volumes, as two or three multi-paper parts or as series of individual papers. In each case, issuance is at irregular intervals, with each volume approximately 1000 pages in length.<br><br>The supply of all volumes of the Kansas University Quarterly is now exhausted. However, most volumes of the University of Kansas Science Bulletin are still available and are offered, in exchange for similar publications, to learned societies, colleges and universities and other institutions, or may be purchased at $15.00 per volume. Where some of these volumes were issued in parts, individual parts are priced at the rate of 1 1/2 cents per page. Current policy, initiated with volume 46, is to issue individual papers as published. Such separata may likewise be purchased individually at the rate of 1% cents per page. Subscriptions for forthcoming volumes may be entered at the rate of $15.00 per volume. All communications regarding exchanges, sales and subscriptions should be addressed to the Exchange Librarian, University of Kansas Libraries, Lawrence, Kansas 66044.<br><br>Reprints of individual papers for personal use by investigators are available gratis for most recent and many older issues of the Bulletin. Such requests should be directed to the author.
