Some notes on archiving

Digital Archiving
We currently digital archive images and documents on a CD or DVD. A PC purchased 15 to 20 years ago would have had a 5.25" and 3.5" floppy drive. One purchased 10 years ago a 3.25" floppy drive and a read only CD. A computer purchased today will have a read write CD/DVD drive and no floppy. How long will the optical, CD/DVD remain the portable storage media of choice? I have no idea but the data is only archived if you can read the media. It will probably be necessary to transfer the data from today's CD/DVD to a new storage medium in the future.

Paper Archiving
Archiving on paper may seem archaic but could actually be more reliable. Early ink jet printers produced images that faded rapidly. Today's quality ink jet printers use dye or pigment based inks that are highly fade resistant. When used with quality coated papers and stored properly they can last for 100 to 200 years. A lot longer than that CD/DVD will be around.

Archiving – Summary

Archive means a collection of historical records especially for Publication, Banking, Insurance, Legal, Education and Government Organization. It also refers to the location where these records are kept in papers, letters, files, diaries or any other documentary materials created by the Individual.

Archives were developed by ancient Chinese, Romans and Greek and the French possess the largest archival collection in the World with records of A.D. 625.

With the tremendous exponential growth in the records led to the creation of paper print, micro film and computer files and for the data preservation process Digital storage in CD Rom was started.

Digital storage has longer life spans and the access technologies that are changing at an ever increasing pace raised the awareness of the Digital Archiving and Preservation among Publishers, librarians and Corporation.

Digital Electronic Archiving (DEA) – its purpose and scope

Digital Archiving is defined as the long term storage for preservation and access to information created in electronic form which includes technical information, data, text, images, audio, video and multimedia.

Several years ago publishers began to realize that if the archival version of their efforts were stored in such a way that it could be reused and get additional benefits & revenue from the repository. So many of the Large Publishers started creating their own archives based on the provision of their product in electronic form.

The speed with which electronic Publishing has grown worldwide Publishers and Librarians have become increasingly concerned about the archiving and preservation of digital information.

It gives access rights for the subscribers to down load any history information because of the availability of physical copies in the archived.

It provides a back – up and may be used to spread across multiple geographic locations. The Archive is not even used for online searching service but it is archived to ensure that its content is not altered.

Costs/Resources –
It was the most difficult aspect as in most of the respondents indicated that they just didn’t know how much the archive was costing or would cost in the future.
For Publishers and producers the cost of archiving is still tied up there is no indication of hardware/software costs now or in the future.
