  1. Taking long term care of your digital resources

    Preservation in the Home

  2. Today we will cover the basics of preserving digital (and analogue) materials and the issues surrounding the difficulties of digital preservation. We will also talk about: Emergency Preparedness Disaster Recovery Introduction
  3. Preservation: activities that prolong the life of your materials Conservation: repair and sometimes reconstruction of damaged items Preservation vs. Conservation
  4. A set of processes and activities that ensure continued access to information and all kinds of records, scientific and cultural heritage existing in digital formats. Long-term, error-free storage of digital information, with means for retrieval and interpretation, for the entire time span access to the information is desired. Digital Preservation:
  5. Most modern information is created in digital format. Digital formats tend to change rapidly or disappear altogether in short periods of time. Reasons For Digital Preservation
  6. is a term used to describe a possible future situation where it will be difficult or impossible to read historical documents, because they have been stored in an obsolete digital format. This could cause the period around the turn of the 21st century, when viewed from the future, to be comparable to the Dark Ages in the sense that there will be a relative lack of written record. The Digital Dark Age
  7. 70 percent of the world’s digital information is created by individuals rather than corporations. 95 percent of the information I surveyed for this presentation was geared towards preservation of corporate records. Preservation of Digital Materials
  8. Preserving Hardware Preserving Software Preserving the Storage Medium Preserving Skills needed to access materials (Knowledge of programs) Preserving Information Ability to locate materials Authenticity of materials Issues in digital Preservation
  9. The tendency of digital materials to become useless because the resources needed to read the data are no longer available. New versions of programs or hardware can render older versions useless. Obsolescence Chamber of Horrors http://oldcomputers.net/ Digital Obsolescence
  10. Strategies in Digital Preservation
  11. Metadata is the data about data and is the secret weapon of the pros in digital preservation. What program created the material, type of computer, etc. try to use the most common and least proprietary file formats when saving your files Rules of thumb in digital Preservation
  12. Unstable media Improper storage Inadequate hardware & software maintenance Human Error Data Corruption Large amounts Benign neglect Hazards in digital preservation
  13. transfer of data between two types of the same storage medium so there is no deterioration in data. Refreshing
  14. transferring of data to newer system environments Conversion of file formats can cause data to deteriorate MIGRATION
  15. Creating duplicate copies of data on one or more systems. Keeping copies in different locations increases the likely hood of the material’s survival. Burn information to CDs or DVDs (always remember to check and see if the data is on the burnt CD/DVD). LOCKSS (Replication)
  16. Storage and Handling of CDs & DVDs Handle discs by the edge Keep them free of dust and dirt Do not use adhesive labels, but mark with a non-solvent felt tip pen Clean with isopropyl alcohol or a cd/dvd cleaning agent. Do not bend discs When not in use, keep them in their cases
  17. External storage How much material do you need to store? How much do you want to spend? How reliable is the product you are selecting? How difficult is the product to use? Does the product have a good warranty? Select the data you are saving wisely. LOCKSS Continued…..
  18. Hard Drive Cases
  19. Using consistent file formats will make preservation easier. Files with less compression are ideal (tiff vs. jpeg) Choose materials with “long term value”. Attaching Metadata to your information Metadata is “data about data”. You will want to keep a record of what program created the information. The progression of migration, etc. Things to Consider
  20. Because your digital information is part of your every day existence, it is just as vulnerable to damage as the rest of your stuff. Fire Flood Theft Hazards to Digital Information
  21. This is best left to a professional. Do not attempt to turn you computer on after it gets wet. Do not attempt to dry your hard drive or computer out. Research recovery specialists. Know who you will go to before the accident/disaster. Recovery of Water damaged items
  22. PART II
  23. Photographs The most tangible representation of our memories. We usually have a lot of them. Storage and handling is becoming increasingly complicated in the digital age.
  24. Digitizing Your Photos It is generally a good idea to digitize your photos. Reduces wear and tear Do not throw away your original Do not rush to remove your photos from albums. If they are in good condition, leave them alone.
  25. Making Digital Photographs Last Rapid changes in technology endanger the life of items that are “born digital”. Migration of formats. Best way to ensure a digital picture lasts is to print it.
  26. Printing Digital Images Using the right combination of paper, printer, and ink is most crucial to digital print longevity. Use archival quality inks and paper Matte coated paper HP Premium Plus Color Fast Epson’s Color Life Paper Most often the manufacturer’s recommendations are best.

  28. Storage of Photographs The best policy is to individually encapsulate each photograph and store in an upright file folder that is supported. If you put them in a scrapbook, use photo corners that pass the PAT test.
  29. Bad Storage
  30. Good Storage
  31. For now, it is the safest long term way to preserve your information. Printing your materials
  32. Selecting the Right Materials Many vendors offer “archival quality” products. Beware! What you use to will determine how long something will last. Be informed, read labels and do research.
  33. “Archival Quality” Materials There are no standards for the term “archival quality”. Use a reputable vendor only. Acid free ph 7.0 or higher. Look for a specific ph.. Alkaline buffered or buffered will help neutralize acid. “Lignin free” or “Lig. Free” is the best.
  34. Permanent Paper The standard defines permanent paper as having a 2% minimum alkaline reserve (to make it more chemically stable), less than 1% lignin, good tear resistance (a measure of durability), and a pH of 7.5 to 10.0
  35. Storage for all types of materials Location, Location, Location! Avoid attics and basements (if you happen to have one!). Be mindful of plumbing.
  36. In Case of Emergency Have an emergency plan Keep your important documents in one place. Make sure everyone in you household knows where these items are. If possible have duplications somewhere else. Consider insurance for very valuable items.
  37. Online Resources Caring for your Collections: The Library of Congress Northeast Document Conservation Center: Preservation Resources Caring for Your Family Archives: The National Archives Minnesota Historical Society Salvage
  38. Making Everlasting Memories: Online Memorial Service Digital Lives Research Project Internet Archive Computers help us preserve our memories
  39. Personal Digital Archiving: Library of Congress Digital Preservation Management Continuing education
  40. There have been no “industry wide” standards adopted for preservation of personal digital archives. Follow the best practices guidelines on the LOC website. Be vigilant, organized and educated Conclusion
