2. LINKS & DEEP THOUGHTS
• “All the world’s a stage” - All the WWW is a linkfest
• “Money makes the world go round”
• Links make the money flow and the world go faster
• Mo’ links mo’ better, mo’ faster? – scamsters’ heaven
• “Not all that shines is gold” – not all that blue is link
• Most scholarly publishers, I/A, aggregator services
learned much from e-commerce linking, but …
• …diagnosis: from link-anorexia to link-obesity
• The good, the bad, the ugly and the dysfunctional
Jacsó
3. What Amazon et al. taught us
Model for rusty library OPACs in browsing,
searching, + LINKING for
• reviews from quality sources
• publisher blurbs, synopses
• sales ranking, bestseller-lists
• TOCs, BoB indexes, LiB, SiB, first chapters
• other works - by AU, by genre, subject
• price comparison/alternatives (doc delivery, anyone?)
• aggregate review consensus sites (MetaCritic, RT)
Jacsó
6. THE BEST & THE REST
free/subscribed bib-cits, abstract, FT databases
OAI pre-, re-, e-print & publishers’ archives, Scirus
• cited, citing, related items, citation analysis in
Scitation, arXiv, CiteSeer, CiteBase, ParaCite
WoS & beyond CSA, EBSCO, Scopus
• journal coverage in Jake, Ulrich’s, Ebsco TSD –caution
• download top lists (Annual Reviews, Elsevier CS, etc.)
• WorldCat member libraries holding stats
• JCR ranking WITHIN category
• Still – some remain linkless and clueless
Jacsó
7. SCHOLARLY LINKS
Linking ≈ citing - refs/cites are THE primary links
• User experience is very much database & host-dependent
• PsycARTICLES – CSA, Ebsco, OCLC, Ovid, Dialog
• Essential, useful & blah links – healthy mix
• Take user to citing/cited/related items (bibcit, abstract, FT)
• Give clue to user about impact of item/journal
• Take user to other works - by AU, by DE, in JN
• Maybe take user to journal/publisher site, e-mail
• Unforgiving syntax rules due to link resolving by SW
Jacsó
8. LINK TYPES by purpose
• Primary functional link (FT)
• Secondary functional link (abstract)
• Tertiary functional link (bibcit)
• Primary enhancer link (citing/cited by)
• Secondary enhancer link (indirect clout indicator)
• Blarney, baloney, eyewash links
• Yes, I know: different folks, different strokes
• Room amenity: T-1 connection vs. ironing board
Jacsó
9. LINK TYPES by vitality
missing link
still-born link + the in-betweens
- aDOA
rusting link
- resuscitable
- dormant
dead link
robust link
link on steroids
Jacsó
10. LINK TYPES by domain
• Intra-document link
• Intra- database link
• Inter-document link (within db/archive)
• Inter-database link (within host)
• Inter-database (within host, subscription dependent)
• Inter-host link (subscription-dependent)
• Inter-host link (partially subscription dependent)
• Inter-host link (partially open access)
• Inter-host link (completely open access)
Jacsó
33. and the citing ones has links to many open access articles
Jacsó
34. except for AJR and JCP which, however, offer the article
for $8 (try this with your Doc Delivery agency)
Jacsó
35. Who Does What?
• Author: explores literature/decides target links -
can be limited due to modest access
• Referee: approves/disapproves links - can be less
or more limited than author
• Publisher: decides linking tool, format, style
• Aggregator: ignores, implements existing links &
creates additional links
• User: activates and (re-) creates links
Subscription-based vs. toll free target
Link-resolver endowed vs. pedestrian users

36. # 2 scenario
If you start in H.W. Wilson’s OmniFile
and General Science FT
Jacsó
37. you get the traditional I/A record with jumpstart link
for AU, SU, and ToC search and then some
Jacsó
38. this is a jumpstart subject search using the
hotlinked Citation analysis descriptor
but you change your mind and want to explore the
WilsonLinks
Jacsó
39. which can run your
query in paid and open
access sources for the
item using the title field
(more or less)
Say, you want to try
EBSCO ASP
Jacsó
40. It does not have FT for the Anseel article
but it has LINKS to 9 cited references
Jacsó
41. so you look at the record and find a link to your library
Jacsó
42. which shows that the 2004 January issue is in - but in Hilo
Try
this?
Jacsó
43. You are not authorized . You store it in your mind for later check-out
Jacsó
44. Return to the EBSCO record to display the cited references
Notice link to Nature article in FT
spot most cited item (#5) by Gottfredson
Jacsó
45. You look up the 6 related items which cite Gottfredson in
Anseel’s cited references
You spot an article which has 216 cited references, another
which was cited 5 times (in journals covered by ASP)
Jacsó
46. you glance at the one cited 5 times, but don’t click
Jacsó
47. rather step back to look at the FT version of the Nature
article
Jacsó
49. Then you remember that you do have access to PsycARTICLES as a
spoiled reviewer, both from OCLC and from CSA.
OCLC shows links to two FT formats, and the record is smartly
enhanced by WorldCat's information about how many member
libraries (2,161) has or had subscription to the journal.
Jacsó
50. While you are at OCLC you look up in WorldCat the journal’s standing
among the psychology periodicals held by OCLC member libraries.
You find that it is the top ranked journal in its league
Jacsó
51. then you switch over smoothly to CSA
Select both PsycINFO and PsycARTICLES and type the query (poor you)
Jacsó
52. It links to both a HTML and PDF version. Some of the cited references also have
full-text links (of APA journals) and abstract links (to PsycINFO records). They
also link to and show cited by figures (within PsycINFO).
You don't
understand
why the first
cited item
(Adair) does
not have full
text and
cited by
value.
Notice this
cited by
value
Jacsó
53. Because APA gave it a wrong title, explosion knowledge not explosion
of knowledge. Not even CSA's smart parser can make the match.
54. Getting suspicious,
you check the
Gottfredson citation
and realize that its
publication year is
1995 instead of 1978,
and know that such
sloppiness by APA
will cause problem
even if the date is
correct in the
original article, as
well as in PsycINFO
(that's why it did
have "cited by"
data).
The metadata is
wrong "only" in
PsycARTICLES.
Jacsó
55. In Dialog’s
implementation
of PsycINFO you
don’t need to
worry about the
typos in the
year, the title,
and about their
consequences
on the links –
‘cause Dialog
has no intra-
database links,
let alone
interdatabase
links (to ISI
databases, for
example, which
are also hosted
by Dialog)
Jacsó
56. This citation mystery whetted your appetite for checking out the Web
of Science (WoS) of ISI to see its cited and citing data. The cited
number is familiar ….
Link buttons
Jacsó
57. …. And the details rhyme with what you saw before. Six of them have
links to the records in WoS. And when you click on the link to see
Gottfredson citedness …
Jacsó
58. the citedness figure is much higher than in ASP or PsycINFO,
because ISI's breadth of citation indexing is much broader and wider
Jacsó
59. While in WoS you take a cursory look at the PsycINFO implementation in
WoS as it is only a quick link away, then you go to the link to look up the
standing of American Psychologist in the Journal Citation Reports,
Jacsó
60. and click on the JCR link button to find out what is the
impact factor of American Psychologist
Jacsó
61. even though you have access only to an earlier edition, the link to its 5-
year citation trends
Jacsó
63. but the Impact Factor is put in the best perspective when you see how it
stands among the 105 journals in the same JCR category of General
Psychology, at a very close second behind Psychological Bulletin
Jacsó
65. Who Does What?
• Who spoils the links? – Most of us some of the time
• Who should mend the fences? - All of us, all the time
• How do you keep your links together for good? - DOI
• How can you mend a broken link? - Ask Al Green
