Yes. Both published and unpublished works can be registered. Copyright in works published before 21st January, 1958, i.e., before the Copyright Act, 1957 came in force, can also be registered, provided the works still enjoy copyright. Three copies of published work may be sent along with the application. If the work to be registered is unpublished, a copy of the manuscript has to be sent along with the application for affixing the stamp of the Copyright Office in proof of the work having been registered. In case two copies of the manuscript are sent, one copy of the same duly stamped will be returned, while the other will be retained, as far as possible, in the Copyright Office for record and will be kept confidential. It would also be open to the applicant to send only extracts from the unpublished work instead of the whole manuscript and ask for the return of the extracts after being stamped with the seal of the Copyright Office.
When a work has been registered as unpublished and subsequently it is published, the applicant may apply for changes in particulars entered in the Register of Copyright in Form V with prescribed fee. The process of registration and fee for registration of copyright is same.
