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

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)

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

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

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 boardJacsó

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)

LINK TYPES - by linking tools

• DOI, OpenURL, PURL, PII, SICI, BICI, ISBN

• Bookmarklets/Favelets – Javascript snippets

• Fee-based LinkResolvers, Home-made utilities

• TinyURL, Short link, Average Link, ALA link

# 1 ScenarioThe conservative, linkless record

Jacsó

Bare minimum record in native PubMed but there are more links than meet the eye

Jacsó

which shows an other directly related record

Jacsó

This is the other commentary on Adair and Vohra's article

Jacsó

Related articles listing is triggered by a small javascript-link on PubMed

Links to subject-wise related records

Jacsó

Link to Ovid is chosen (if you subscribe)

Jacsó

Finds the full record in

Journals@Ovid Nice intra-record

links and option links

Jacsó

but having only navigational links (except for the link to an open access journal Current Research in Social Psychology (CRISP) is not enough)

Jacsó

You may continue in Ovid to explore other articles on self-citation

Jacsó

and find 43, many of them ALSO available as open access journals in case you don’t subscribe to all

Jacsó

which is easy to Google even without guidance, and the link will take you

Jacsó

to PMC with a link to FT …

Jacsó

… of the article which has many extra link options (alert request, insta-comment)

Jacsó

and you can make a search in CMAJ on the broader topic

Jacsó

finding an article by Garfield with cited/citing references, of course

Jacsó

most of which are hotlinked not just listed

Jacsó

and the citing ones has links to many open access articles

Jacsó

except for AJR and JCP which, however, offer the article for $8 (try this with your Doc Delivery agency)

Jacsó

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

Jacsó

# 2 scenarioIf you start in H.W. Wilson’s OmniFile

and General Science FT

Jacsó

you get the traditional I/A record with jumpstart link for AU, SU, and ToC search and then some

Jacsó

this is a jumpstart subject search using the hotlinked Citation analysis descriptor

Jacsó

but you change your mind and want to explore the WilsonLinks

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

It does not have FT for the Anseel articlebut it has LINKS to 9 cited references

Jacsó

so you look at the record and find a link to your library

Jacsó

which shows that the 2004 January issue is in - but in Hilo

Jacsó

Try this

?

You are not authorized . You store it in your mind for later check-out

Jacsó

Return to the EBSCO record to display the cited referencesNotice link to Nature article in FT

spot most cited item (#5) by Gottfredson

Jacsó

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

you glance at the one cited 5 times, but don’t click

Jacsó

rather step back to look at the FT version of the Nature article

Jacsó

in all its glory

Jacsó

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

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

then you switch over smoothly to CSASelect both PsycINFO and PsycARTICLES and type the query (poor you)

Jacsó

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).

Jacsó

You don't understand why the first cited item (Adair) does not have full text and cited by value. Notice this cited by value

Because APA gave it a wrong title, explosion knowledge not explosion of knowledge. Not even CSA's smart parser can make the match.

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

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

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 ….

Jacsó

Link buttons

…. 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

the citedness figure is much higher than in ASP or PsycINFO, because ISI's breadth of citation indexing is much broader and wider

Jacsó

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

and click on the JCR link button to find out what is the impact factor of American Psychologist

Jacsó

even though you have access only to an earlier edition, the link to its 5-year citation trends

Jacsó

It Is quite telling in and by itself

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
