Motocom, Inc., d/b/a RepairManual offers access to a diverse repair manual library. In-as-much as our roots are grounded in motorcycles and motorcycling, we offer repair manuals relating to cars, trucks, vans, all terrain vehicles, snowmobiles, tractors, and personal watercraft.
Two broad classes of repair manuals are offered by RepairManual on Ebay, namely, reproductions of original repair manuals, and original repair manuals, i.e., titles of others, which we purchase new or used from OEMs and publishers via their authorized distribution channels 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 offer copies of public domain content, more particularly, titles published prior to 1989 and without active copyright. 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-Beme 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 and parts, we by necessity make use of trademarks and/or trade dress of others to describe the items we offer. In doing so, no representation of affiliation, association or the like is intended, unless otherwise stated. Moreover, we are in fact owners of intellectual property, property that is a valuable asset to our business. If you are a copyright owner we ask that you please contact Mr. Lenard Nelson at 1-828-284-0944 (Monday - Friday / 9am - 5pm EST) to answer any questions or remedy any trademark or copyright concerns. Thank you.
