Issues are discussed in all of the above bullets. Access is discussed in particular under Information Retrieval above.
Searching is discussed in particular under Information Retrieval above. It is also discussed in several articles in the Fall 1994 WWW conference.
Browsing covers a broad range of human-computer interaction, including hypertext, hypermedia (covered earlier in this course), visualization, and menu systems (e.g., gopher). It relies upon the fact that humans are better at recognition than remembering. However, it requires manual or automatic schemes for categorizing and structuring (recall discussion of clustering under Information Retrieval above). There are sophisticated browsers build into languages like Smalltalk, operating systems like NeXTstep or Apple Macintosh (with its Finder) or separately constructed for information access (see upcoming Rao et al. article in April 1995 CACM).
Linking relates directly to hypertext and hypermedia. Those technologies make use of links to facilitate interaction. Forming those links is commonly done manually, but can be automated by using clustering methods (recall discussion under Information Retrieval above). Soft links are dynamically computed, sometimes as a result of a search.
Authoring is at the heart of Electronic Publishing, discussed above.
Please see the JASIS issue listed below under More Sources for key articles on Copyright and Subscriptions. It is on reserve in the Library under "Fox" for "CS5604". Copyright is covered in the article by Garrett, who worked for the Copyright Clearing House and now works for CNRI with Bob Kahn (inventer of Knowbots). Subscriptions is covered in the article by Rawlings, who believes this approach will revolutionize electronic publishing and make digital libraries a great success.
