Did you really think that the Census Bureau was just too lazy to go back to the paper originals? No, I would have thought that sifting through 200 million or so census papers (or, if stored by State, still four or more million) was not cost-effective, so was vetoed by government. It would have meant comparing every paper with the digital record to find the missing ones, a huge task. In fact, it would probably be simpler to just re-enter the entire census again. The original census papers were destroyed? That surprises me, Jeremy. My wife is a genealogist, and she subscribes to various websites and buys dozens of CD's with digitized images from old English Census papers, going back to 1841, the year of the first real census in England. These are still stored by the Public Records Office in England, and have been accessed by people like Rod Neep for the purpose of making digital records of the original papers which are then available for all interested parties. My own country, New Zealand, destroyed census records until some time in the 1900's, a wanton act of vandalism IMHO, but I am totally surprised that the USA has detroyed theirs. Colin D. It is a fact, nonetheless. The data is corrupt and cannot be reconstructed. The original documents were destroyed, apparently in the belief that their retention was just going to take up space. There are lots of similar horror stories out there. LONG-TERM digital archiving has its risks, and microfilm offers a robust and time-tested solution for an alternative backup source. |

I am not sure where all you are going with this. Using a silver-based film to store high contrast documents is rather different then storing color photographs. History has already shown that color negatives do not do at all well and slides have a limited life as well. You make it out that digital archiving is doomed to fail but there are a lot of people who are right now doing digital archiving and have been for some time. And I am not sure what you are advocating, that people not shoot digital because they will loose their photos if they do? That people show transfer their photos to slides as a form of backup? In industry there are all sorts of things that never get backed up as a hard copy. I don't know of any software company that backups up their source code on paper. If you loose the digital version you are pretty much hosed. Board layout is the same thing, it is all stored as a digital file. Mechanical designs are now all solid models and rarely backup on hardcopy. If a company can't safeguard their digital data these days then they are in a world of hurt, regardless of what hard copy backups they might have. By the way you don't have to do so much SHOUTING. We can read lower case just fine, if you feel the need put on of these guys in! Scott |

I have had negatives fad in just a few years, less then 5, agfa print film in even less. I have had slide grow mold. Prints do better but still are subject to some slow fading. I have yet to lose a digital file and of course none of them have faded at all so even if a print only fades 1% a year the digital is still ahead. Scott |

It is rust that really gets to everything here. A few other people also have worries about filme http://www.loc.gov/preserv/care/film.html http://www.filmforever.org/ http://www.royalbcmuseum.bc.ca/conservation/photog.html http://palimpsest.stanford.edu/byauth/roosa/roosa1.html Well the list goes on and on but there are several things to be learn, only BW is long lasting, color all fades some faster then others. Noboy views color slide, negatives or prints as a good long term media for photographs. I have had prints out last the negative, as in this case http://www.pbase.com/konascott/image/55744935 I have had agfa print film go so bad in about 10 years that the color look like total crap. If you read about film conservation you will learn that all color film fades, the best you can do it slow down the fading. The time to fade is given in decades at best. Scott |

To be fair to the digital guys, the Department of Defense, and the defense and aerospace industries in general, are very conservative and tend to be slow to commit to new technologies. Actually, I think it has more to do with micro-fiche can be read with absolutely no electricity. |

There are lots of similar horror stories out there. LONG-TERM digital archiving has its risks, and microfilm offers a robust and time-tested solution for an alternative backup source. Data from the US Census is never intentionally destroyed. The Census is required to be conducted every 10 years for the purpose of determining representation, and the data is a historical government record. There have been some accidents with Census data, notably the 1890 Census which was almost completely destroyed by a fire in the Commerce Department in 1921. Prior to the creation of the Census Bureau, the Commerce Department was responsible for conducting the Census. |

Jeremy wrote: Kodak has gone on record recommending that consumers consider making prints of special shots, and keeping them stored in archival albums, just in case their digital files are lost due to corruption of the media they are stored on. Funny how Kodak keeps recommending that people use their products. There is some truth to what they say and I do make a number of prints. So far from personal experiance this is what I have seen. Digital images have lasted the best, next is prints. next slides last negatives. I am not saying that digital storage does not have risks, but with a bit of care they can be pretty much eliminated. Scott The National Archives does not agree with you. When the Clinton Administration ended, they looked for a way to archive the millions of email messages that were on the White House mail servers. They ended up printing them onto paper, then microfilming the paper and also storing the paper. I bet they kept digital files as well, and the microfilm/paper versions were intended as secondary backups only. The tone of your post seems fixated on the problems of digital storage, but there are considerable problems with physical or analog storage as well. The sheer space requirements, indexing, and searchability issues are major with document storage. Imagine someone saying "I remember Bill Clinton mentioning something about xyz in an email, way back." How would you set about finding that email in a pile of millions of email printouts? Or on microfilm? Whereas, searching a digital archive would return you *all* mentions of xyz in a fraction of a second, as you no doubt know. Basically, once the amount of data stored with hard copy or analog methods exceeds a critical point, that data is already effectively lost, since the effort to find a given piece is beyond the time available to find it, and the relevance decreases with time as well. Lawyers have this problem with case law. The Department of Defense requires certain sensitive or critical plans/schematics/operating instructions to be submitted on microfilm, in addition to any other electronic format such as PDF. Again, I would think as secondary backup. Part of the 1970 US Census has become lost to us, because the data files can no longer be read. One of NASA's missions to Mars has had a portion of its data lost because of corrupt and unreadable digital storage. Part of the census problem is, as mentioned above, the sheer volume of data from hundreds of millions of people, not to mention the statistical derivations from that data. Way back in the year 1890, Hollerith invented a sortable system of cards with punched holes around the perimeter, to aid in speeding up the census results. In the 1900's IBM and others got into the act with early computers. The actual census returns were and are still stored as paper, and whatever calculations and statistical results are required are now done with the computer data derived from the paper. It is simply impossible to do it any other way within a useful timeframe. The parts of the 1970 census you say have been lost could be recovered from the original stored paper - if sombody had the time and necessity to do so. And that highlights what I said earlier about that data being effectively lost, even though it still exists. Nasa has lost more than that Mars episode. But, is it really lost? or is it stored in a now unreadable format? This is the same problem that those concerned about digital archival storage keep mentioning - compatibility lost because of neglect to transfer the data to newer standards. If they *really* needed to read that data, they could locate or build gear that could do it. If the effort is greater than the need, then it won't get done. A new paradigm is needed here. Old ideas of archiving data meant physical storage in a controlled environment, to preserve the original documents as long as possible. Data was not considered as being separate from the medium on which it is stored. Data storage was evolutionary; better climate control, inert gas storage, low-light environment, all of which extended the life of the media, but when the media finally becomes unusable the data is lost. The paradigm needs to be shifted to realize that the *information* stored is what is being kept, not the medium on which it is stored. And if it is trivial to transport the information to new media at intervals, then that is what should be done. Paper will eventually decay, microfilm will eventually decay. *Information* decays along with it. Until now. We have, with digital storage, the capability to store data *for ever*, without decay, simply by regular and timely transfer of data to new media. That capability, in anyone's language, is a revolution. Colin D. Well, there is no point in your arguing this with ME--you should call the various Government departments that insist upon microfilm and tell them that they've got it all wrong . . . You are apparently convinced that long term archiving (i.e. for centuries) is a simple affair--one that can be easily implemented. From what I've been reading, institutions charged with maintaining digital collections do not seem to agree with your perspective. While digitization clearly offers benefits for short time horizon uses, people that a re a lot smarter than me have gone on record as saying that there are long-term issues that have yet to be solved, and that analog storage offers a margin of safety for the time being. By the way, the Census data CANNOT be reconstructed, because the paper original documents were destroyed, leaving only the digital data. Did you really think that the Census Bureau was just too lazy to go back to the paper originals? Another thought occurs. (some are painful!) Way down here at the end of the earth, the possibility of a nuclear blast is pretty remote, but I wonder if the authorities in America are worried about a possible magnetic pulse from a nuclear attack wiping out all magnetically-based storage, and hence use non-magnetic storage media for archival records? If that is the case, then microfilm would indeed seem to offer the best medium - provided it wasn't at ground zero. Reminds me of the report about a Russian pilot who defected with his MIG to Japan. When they inspected his aircraft, the inspectors laughed themselves sick at the sight of all the primitive valve-based circuitry, not a diode or transistor anywhere. That was until somebody realized that valves were immune to radiation and magnetic pulses, whereas solid state ... Colin D. |
