Document Content refers to the substance of the material or information within the document that is intended to be communicated.
Intellectual Content refers to the ideas, thought processes, artistic expressions, etc., contained within the document.
<Copyright refers to a means of legal protection provided to the author(s) of original published and unpublished works that have been "fixed in a tangible form of expression," in order to afford such authors the exclusive right of exploitation, in particular the right to control the reproduction, distribution, performance, or display of the work, or to control the preparation of derivative works.  Often, exploitation of the work by others requires the consent of the author(s) and the payment of a royalty to the author(s), usually in the form of a fixed sum of money for each copy made, shown, or distributed.
For works copyrighted in the United States after January 1, 1978, protection afforded to the author(s) or the author(s)' estate is usually for the author(s)' lifetime plus 50 years. For works created prior to that date, the copyright period was 28 years from the date of publication (or the date of registration of copyright for unpublished works), plus an additional period of 47 years for works whose copyright was renewed during the last year of the first term.
Works published in the United States may be afforded protection in countries that were members of the Universal Copyright Convention or of the Berne Convention for the Protection of Literary and Artistic Works. Conversely, works published in such member countries are protected within the United States.
Most works that are the subject of preservation interest were published before 1978. The copyrights on the majority of those works were not renewed for the optional second term. Thus, the copyrights have expired on most of the works of current preservation interest that were subject to United States copyright protection. However, since this is not true of all such works, the normal practice is to check copyright ownership to verify clearance.
Structure refers to the divisions within a document provided for ease of access, reference, and other purposes. The broad structure of a given document is likely to vary according to its format (1.2), and there is also not necessarily any standard structure for a given format. With its long history, the structure of the printed book (1.2.2) has evolved towards a somewhat standard structure. Because of the focus of this Glossary on the preservation of the printed book, a typical book structure is presented here and structures for other formats are omitted.
The Title Page of a work normally contains the title of the work, its author(s), and the name of the publisher.
The Body of a document refers to the main corpus of the work. It may be divided into characters, chapters, articles, or other segments.
This category includes publisher's notes, credits, frontispieces, and other minutiae of publication.
