Integrating Local and CRI Online Documentation Using SGML and DynaWeb 
This paper tells how Lawrence Livermore National Laboratory enriched CRI's online documentation set by publishing local manuals using the same SGML DTD used by CRI and delivered using (a more sophisticated version of) the same World Wide Web server (DynaWeb 3.0). This approach supports flexible local content and styles, yet integrates local and CRI manuals through one access mechanism and user interface. We explain the basic strategy involved, compare the benefits of this approach with three alternatives, and discuss the problems to which it gives rise.
