From last time…
Identifiers:
Locating a resource via a permanent channel
Solving the appropriate copy problem
Accessibility and limiting access part of the same problem
Copyright issues
Is copyright important for a particular scenario / document?
If so, how to protect it?
Determining scope of property rights?

Two worlds: digital and print media

Models for digital economies
Subscription fees
Per month, per year
Connection time fee
Per minute (e.g., Mead Data Central)
Advertising
By an interested party
other economic models apply here
Access fee
Per download, may not have profile to remember that you accessed this resource before
Per-byte fee
Typical of connection services (e.g., Broadband)

Cost structuring
Movie distribution as a possible model (Lesk, p. 206)

Access versus ownership
With DL materials we can’t really track ownership, just access
Trend towards microanalysis
Publisher: better targeted marketing
Library: better profile of user community

Crisis for publishers
Ease of publication allows more information to be free
And for people to break copyright
(perhaps accidentally)
Ease of accessing (free) information deters users from accessing more cumbersome-to-use sources
Traditional functions of publishers are taken on by free services
Free e-journals do rigorous peer review
Search engines act as distributor

Self-archiving
To deposit a digital document in a publicly accessible website.
Preprint: before copyright restrictions have been signed
Not a true publication*: hasn’t been peer-reviewed, not in prestigious publication.
Detractors: accessibility will hurt future revenues of the journal
Perhaps 60-80% of a publisher’s budget doesn’t go towards the direct publication costs

E-prints
Differing acceptance from different fields
Physics: accept only if concurrently preprinted
Medicine, Business: accept only if not preprinted
E-journal model: who assumes the cost?
Authoring a text Author
Peer review Peers
Marketing Search engine
Editor E journal
Publication E journal (disk space 
and expertise)

Peer review limitations
Goal of peer review is to insure:
Previous work adequately acknowledged
Experimental methodology realistic and reproducible
Analysis of data justifies conclusions
Peters and Ceci (82):
Resubmitted 12 psychology articles already published with different author names, 8 of 9 recommended against acceptance and were rejected “serious methodological flaw”, not because of déjà vu.
Inglefinger study of NEJM reviewers:
Concordance of reviews only slightly better than chance
Reviewers not skilled in all areas of a study, unable to discern poor writing and have their own biases

Legal Deposit

Internet Archive and Bookmobile
Internet Archive
http://www.archive.org
An archive
of the www
“The goal of universal
access to our cultural
heritage is within our grasp.”
Are these examples of legal deposit?
Who funds this initiative?
Internet Bookmobile
Prints out of copyright books for reading
Over 1m books
$1 USD per book printed

Preservation
Y2K – two digits to mean four
If you knew COBOL, you could get a high paid job.
Legacy systems and knowledge need to be preserved
Use standard formats!
Media lifetime
Tape 15 years
CDR 10-50 years
HD 30 years
Software/Hardware lifetime
New hardware 3-7 years
Software cycles faster
How to access old files, applications?

The Digital Divide
A case of the rich getting richer?

Undoing the Divide
Can use access rights to impose an unequal payment scheme
Blackwell’s – all 600 journals made free to the Russian Federation.
JSTOR – cost to access its DL depends on the size of the organization.
Open source movement – make software available to anyone

Libraries of the Future
Immediate, random-access to recent knowledge
May not understand foundation material
More effort in selection of materials
Publisher models changing, unifying
International policy becoming more prominent
Customized books as the future?

To think about…
How does the economics of libraries and the information explosion influence publication rates?  What about as we make the transition to the digital library?
Do you think self-archiving and e-journal venues pose a threat to the journal publisher?
As a single site, the Internet Archives, cannot keep track of all web pages on the web
Can you think of a better solution?
How would you go about designing a national web page archive for Singapore?
