Summary
Hypertext links connect nodes and pages together. They are the defining characteristic of hypertext. From one page of content, a single selection takes you to another page.Links are an implicit endorsement of the destination page. A search engine may use the link structure to identify important pages.
Pages may be linked for many different reasons. A link may expand on a topic, refute an idea, present an example, or discuss an idea. Links may be categorized by type or by location.
Links may be permanent or generated dynamically from a database. Links may become out-of-date or otherwise disconnected. (cbb 4/07)

Quote: the essential feature of hypertext is machine-supported links [»conkJ9_1987] Quote: links (associative index) is the essential feature of Memex [»bushV7_1945] Quote: in a Hypertext system, it should be easy to follow a link [»conkJ9_1987] Quote: HyperCard is not Hypertext: no links embedded as part of text; no bidirectional links; no graphical browser [»conkJ12_1987] Quote: index the anchor text as a title of the target page; helps identify a document; good for Web searching [»zobeJ7_2006]
Subtopic: links are connections between things
Quote: hyperlinks are endorsements for web pages; a network of recommendations that identifies authoritative documents [»boroA2_2005] Quote: a hyperlink confers authority on the target; a latent human judgment [»kleiJM9_1999] Quote: hubs and authorities exhibit a mutually reinforcing relationship; a good hub points to many good authorities and vice versa [»kleiJM9_1999] Quote: determine hubs and authorities from a neighborhood of the 200 highest ranked pages for a query [»kleiJM9_1999] Quote: the iterative algorithm for hubs and authorities converges to the principal eigenvectors of the weighting matrices [»kleiJM9_1999] Quote: a hyperlink is an endorsement of the page; use links to measure their relevance and quality [»chakS8_1998] Quote: Clever analyzes hyperlinks to identify authorities on a topic and hubs with links to authorities [»chakS8_1998] Quote: high PageRank if many pages point to the page, or if highly ranked pages point to the page [»brinS4_1998]
Subtopic: binary data
Quote: Hypertext links should follow from a model of the user's need for information to perform a task [»glusRJ5_1989] Quote: all facts are connections between things instead of attributes or relationships [»kentW1_1984] Quote: links are part of writing a document; for exploring information [»nelsTH_1987] Quote: linked representations and the existence of representations is the fundamental basis for representing information [»kentW_1978] Quote: a Dexter hypertext is made of components, i.e. an atom, a link between (parts of) components, or a composite of components [»halaF2_1994] Quote: Dexter uses anchors for span-to-span links; i.e., a (component unique) anchor id and a changeable anchor value (internal reference) [»halaF2_1994]
Subtopic: link as purpose/type
Quote: reference binary data as a with MIME type and size; allows consumers to make intelligent choices about fetching [»boswA10_2005]
Subtopic: link as a relationship
Quote: use self-describing links with purpose and MIME type; e.g., purpose="comments" type="text/atom"
Subtopic: links identify chunks
Quote: Hypertext link is a relationship between a source and destination node [»raymDR7_1988] Quote: a Hypertext link asserts conditional dependency between the utilities of two cards [»frisME7_1988] Quote: a Hypertext link conveys a relationship between nodes relevant to readers [»trigRH1_1986] Quote: NoteCards forms a semantic network of notecards connected by typed links [»halaFG4_1987] Quote: PROMIS forms a branching network of displays which integrate values, knowledge, and patient data [»waltPL11_1979]
Subtopic: permanent link
Quote: XML doesn't handle links; the division of the data world into chunks depends on the person and purpose [»boswA10_2005]
Subtopic: embedded link
Quote: permanent document links by disallowing change; e.g. legislative and judicial document collections [»ashmH9_2000]

Subtopic: links vs. hierarchy
Quote: trigger KMS scripts by left button, same as links; distinguish by hollow bullet for links and solid bullet for actions [»akscRM11_1993]
Subtopic: linked windows
Quote: IGD stitches a chapter's pages with links instead of defining a hierarchy [»feinS3_1988] Quote: IGD page graph from actions which access neighboring pages when invoked
Subtopic: examples
Quote: a zippered list consists of enduring, pairwise links between elements [»nelsTH8_1965] Quote: shared window showing group calendar that scrolls with a private calendar [»sariS10_1985] Quote: derivative text motion--two windows such that one window moves according to the other window, e.g., table of contents and text [»nelsTH_1974]
Subtopic: orphaned links
Quote: NoteCards links for building networks of related cards Quote: PROMIS frames are interrelated in a network; with links displayed in frame Quote: KMS items can be linked to another frame or to a program (or both) [»akscRM7_1988a] Quote: NoteCards link is a typed, directional connection from icon in source to destination card [»halaFG4_1987] Quote: Thoth-II is based on Hypertext as a directed graph [»collGH11_1987] QuoteRef: palmJ5_1973 ;;6 Simula uses :- for linked to
Subtopic: links not important
Quote: a link requires the continued existence of its objects; what happens when object is deleted [»kentW_1978]
