Web archiving: what & why
4
“Web Archiving”: Assumptions Using automated methods to gather web content Building some kind of collection composed of more than one site Intent on preserving captured content Results are searchable –Public access may not be available
5
How is the material at risk? Vulnerability of –Digital publications –Web publications –Government web publications –Local government web publications
6
The Ephemeral Web
7
Issues Unique to Government and Political Web Documents Publication & notification streams Elections, political change Security vs. freedom of information Local agencies often don’t have the resources to archive their own publications

Beyond the Grant Support web archiving for the University of California –Enable collaboration across campuses –Enable collaboration between librarians and researchers/faculty
13
Web Archiving Service (WAS) Tangible outcome of grant work Being developed and release over a series of pilot tests Pilot test 5 underway until May 23 2008-2009 develop rights management and public access features
14
WAS Production Early summer 2008, Web Archiving Service goes into ‘limited’ production. –Available 24/7 to the curators who have taken part in the pilot tests so far Expand user community within UC as CDL confirms that WAS infrastructure, user support and training is sufficient.
15
Web Archiving Service Workflow and Sample Screens
16
WAS workflow Project > Site > Capture > Collection Set up a project (usually a topic or event) Define the sites to capture Run single or multiple captures of each site Choose which results to add to a single, searchable collection
18
Capture sites individually
19
Set Frequency
20
Add metadata (or not)
22
Sites can be captured in batches
23
When Capture Finishes
25
Display Results (QA capture effectiveness)
26
Display Results: Overview & Reports
27
Display Results: Full Text Search
28
Display Results
29
Display Results (metadata)
31
Create Collection
32
Build Collection (add entire captures)
33
Build Collection
34
WAS features for analysis It’s impossible to know what a web site ‘contains’ until after you capture it! Tools for understanding where the data comes from and how it has changed.
35
What’s the nature of this content?
36
What new publications are in this capture?
37
Build Collection ( Select files from “Compare” screen)
38
How volatile is this site? (Not yet available)
39
Potential We can now capture the “chit chat” – the popular reaction to historic events, in ways never before possible. How will researchers interact with captured content once it is in an archive? –Visualization –Text analysis What is the potential, beyond simple search and display?
