To provide direct and enhanced access to Web resource, CyberStacks(sm) seeks to make full use of the capability of the World Wide Web itself and the versatility of Web browsers. Key to the CyberStacks(sm) system is a browsable classification scheme that allows users to scan broader or narrower subject categories at will, and then if desired to connect directly to a selected resource.
While the overall organization and structure of CyberStacks(sm) facilitates access to Net resources, access has been further enhanced by the establishment of a matrix of search and browse functions. These include its Combined Classification Index, with selected sections shown below (Fig. A-3),

A function that would allow users to link directly from a structured thesaurus of all Library of Congress Subject Headings (LCSH) entries assigned to resources within its collection, currently under development for CyberStacks(sm), would also greatly facilitate access to relevant resources, within the InterCat and NetFirst(tm) databases. As envisioned, such a hypertext thesaurus would outline all the entries assigned to resources in its database, indicate the broader, narrower and related relationships between entries, and provide a hypertext link directly to those records assigned a specific heading.
In cases where a given subject heading has been assigned to more than one resource, users would be provided with a menu of options, including an alphabetical title listing of all resources assigned a specific heading. From this listing, a selection would link users directly to the associated profile within CyberStacks(sm) for that resource, from which users could then subsequently connect.
In addition to adopting the 'neo-conventional' functionality outlined above for CyberStacks(sm), the InterCat database and the NetFirst(tm) service could also benefit from an online subject tree arrangement of the Dewey Decimal Classification, adapting the general (Fig. A-6)

and specific (Fig. A-7) outlines used by the NISS Information Gateway in its use of the Universal Decimal Classification (UDC) to organize and provide access to resources selected for its cybercollection.

These services could also be enhanced by adapting other features of the NISS service, including a Directory of Subject Headings in UDC order (Fig. A-8)
0 Generalities - 37 resources
00 Knowledge. Fundamentals of knowledge and culture - 0 resources
01 Bibliography - 22 resources

02 Librarianship - 30 resources
03 Reference works - 25 resources

as well as a Directory of Subjects in Alphabetical Order (Fig. A-9).

Such enhancements not only facilitate access by providing direct connection to a resource, or to a profile if desired, but like the CyberStacks(sm) approach, present a framework in which relationships between and among resources are indicated.
The use of formatted tables within CyberStacks(sm) presenting broad and specific subjects and their associated call numbers, as well as links from each class to related classes through a variety of structured hotlinks (Fig. A-10), enhances navigation through the CyberStacks(sm) collection, and could likewise enhance access within reconfigured InterCat and NetFirst(tm) databases.

The use of appropriate icons in CyberStacks(sm) in association with broad and general subjects, at primary and secondary levels (Fig. A-11), offers users visual clues that also can facilitate access to resources of potential relevance within its collection. OCLC should consider use of similar icons within a redesigned interface to both the NetFirst(tm) and InterCat databases to further enhance access and use of these resources.
