What is the World Wide Web?
A huge collection of digital documents (websites) which are stored on special computers (web servers),
interconnected with each other.

What is on the web?
What isn’t on the web?
Why save the web?
1. More and more items are born digital only material!2. Some websites contain unique data and valuable
information.– Users take action and make important decisions based on this
information.
3. The web is a live record of contemporary:1. Society,2. Culture,3. Science,4. Economy.
4. Responsibility to preserve the web.5. Transparency is promoted by saving the web.
Isn’t the web already safe?
• The answer is: NOT really!• Websites are in danger:– Organisations that maintain them stop caring about them,– Organisations than maintain them cease to exist,– Natural disasters destroy computer facilities (fires, floods,
storms, etc)– Technical problems damage websites (bugs, computer
viruses, backup failures, hardware failures)– Their data are tampered on purpose!!! for many reasons
(political, financial, crime, etc)
A major blog hosting company was shut down by the U.S. Authorities
Yahoo GEOCITIES has closed.
Natural disasters cause data center problems
Websites are tampered all the time
Websites are tampered all the time
Does this sound familiar?

WEB ARCHIVING
The process of collecting portions of the World Wide Web to ensure the information is preserved in an archive for future researchers, historians, and the public.
Challenges
• How it is done technically?• What should I choose to archive?– The whole website? some pages? Some files only?
• What do I want to do with the web archive I’m creating?
• Who will have access?• Who is the owner of the web archive content?
Archiving web pages is a technical challenge

Who is working on web archiving?
Many important organisations work on web archiving since 1996.
International Internet Preservation Consortium
• IIPC Members– National Libraries,– Academic Libraries,– Cultural Organisations,– Universities,– Software development companies
• Web Archiving Timeline– http://timeline.webarchivists.org/
Obligation of the National Library
• According to UNESCO:– «a national library is responsible for the
collection and storage of the national cultural heritage».
• In Greece, accoding to law No.3149/03:– «publishers or authors (when there is no
publisher) of any printed material, are obliged to submit three copies of their work to the National Library of Greece. This obligation also includes audiovisual and e-publishing material».
• What about the Greek web?
Bibliothèque nationale de France
2006: legal deposit extended to “signs, signals, writings, images, sounds or messages of any kind communicated to the public by electronic means”.
The goal is not to gather the «best of the web», but to preserve a collection representative of the webat a certain date.

• Making your own web archive.
Making your own web archive
• Using HTTrack software (Open Source)– Installation– Practical advice– Features– Usage scenarios• Archive http://2013.futurelibrary.gr/ • Archive http://www.auth.gr/
Things worth considering• Set Limits
– Filters to define the file types you want to copy.– Bandwidth limits & Connection limits to avoid overloading the site you are
archiving AND avoid saturating your library network.– Time limits
• Check the size of the files you have downloaded.• Plan for disk space according to your needs.• Check target website copyrights. Are you allowed to:
– Archive for personal use?– Archive for public use in library computers?– Archive to publish on the web?
• If you are not sure, please ask the website owner before beginning web archiving.
Scenario: create your own mini web archive in your library on a shoestring.
• Equipment:– Typical Windows computer with the biggest possible hard disk. (The
more ΤΒ, the better).– Equal backup disk (e.g. External USB hard disk).– DSL Internet connection.– HTTRACK open source software
• Select important local websites.• Get permissions from website owners if necessary.• Setup a regular web archiving schedule (e.g. Once per month).• Provide information and access to the web archive in your
library’s local computers for the public.
