Jensales Inc. has the largest and most diverse tractor and industrial manual library in the world. Our titles cover nearly every tractor made from 1900 to the present, and the legendary industrial equipment you have from Caterpillar, Huber, Allis Chalmers, even those old Bucyrus Erie monsters! With over 16,000 manuals in our library, from nearly every manufacturer, we probably have the one you need.

Two broad classes of material are offered by Jensales, namely, reproductions of original farm and industrial equipment manuals, and original farm and industrial equipment manuals, i.e., titles of others, which we purchase from the OEM's (Original Equipment Manufacturers) via their authorized distributors and pass on to you our customers. In connection to our content, we strive to locate, secure and clear the titles we make available to you directly as reproductions.

As to the former, namely our reproduction titles, we do offer copies of public domain content, more particularly, titles published prior to 1989 and without copyright notice. For decades, an outstanding feature distinguishing United States copyright law from that of the rest of the world has been an emphasis on formalities, among other things a requirement that the public be given formal notice of every work in which copyright is claimed. This facet of the law has origins in the original Copyright Act of 1790, and has remained in the successive Act revisions of 1831, 1870, 1909, 1976 (effective 1978). Many of the formalities under the 1909 and 1976 Acts have been lifted with the accession of the United States to the Berne Convention, via passage of the Berne Convention Implementation Act of 1988.

Before 1978, federal copyright was generally secured by the act of publication with notice of copyright, assuming compliance with all other statutory conditions. United States works in the public domain on January 1, 1978 remained in the public domain under the 1976 Copyright Act. As of March 1, 1989, the effective date of the Berne Convention Implementation Act, copyright notice, among other things, was prospectively eliminated as a condition to copyright protection. However, where a copyright notice is required, essentially for all published Pre-Berne content, and its omission is not excused, the legal consequence is to inject the work into the public domain.

In connection to our business, namely the offering of manuals, we by necessity make use of trademarks and/or trade dress of others to describe our goods. In doing so, no representation of affiliation, association or the like is intended. Moreover, we are likewise owners of intellectual property, among other things, federal trademark registrations for JENSALES, JENSALES AGRICULTURAL YELLOW PAGES, and AGRICULTURAL YELLOW PAGES.
