Several years ago, the Wheeling-Ohio County library announced they were going to give away all of their bound years of The Intelligencer and The News-Register, with any unwanted years getting landfilled. They later changed that to "two volumes per person, extras after everyone picks them over." As the event approached, all three of us went up, intent on snagging two per person and figuring out what to do with them later. We were in line with at least fifty other people, all local historians ready to do the same thing when the librarian announced they wouldn't be giving the copies away, after all, because the newspaper wanted them all back. She seemed astonished that there was any use for hard copy when they have microfilm.
Right now, the state of West Virginia is trying to scan and digitize them all. Because it's a nearly complete collection from 1852 to the present, that means before many years go by we'll have access to freshly scanned, crisp copies of the run-up to the Civil War, among other major events. The old photographs of Wheeling's many unfortunate events won't be blurry gray and black blobs any more (and no one will have to go through the paper's morgue to unearth them.) Best of all, we won't be working from microfilm that has been scratched or broken from much use.

… This issue surfaced just last week with technical materials from a locomotive overhaul and update program authorized in 2000 and completed in 2001-2003. Some software was discontinued in the years since then, the file types are no longer supported even in later software packages from the same manufacturer, while other file types that you would think are still supportable are now blocked by the original manufacturer through changes in registry settings.

Sorry but that just sounds a bit like an "apocryphal tale", or at least one in which the actor declared defeat prematurely owing to preconceived notions. First the ongoing indifference to keeping documents version-current. Second the registry doesn't do that, so trivial IT intervention here would have sufficed. Third, no extreme-but-cheap efforts like buying an old PC off Craigslist to run an old version of the software, or simply waving $50 around on eLance to hire the conversion done.

This is actually similar to the "backup problem" where a backups are made dutifully for years but never tested. In this case, software versions were updated, and compatibility with existing documents was left to chance. Don't do that LOL.

But a quick and easy solution was available. One "mint" set of the printed publications that sat unused on a shelf for 15 years, converted to searchable PDF, and subsequently to the needed current electronic formats. It proved far less of a hassle than dealing with the updating of file types that have been obsolete for a decade.


Only problem with that, is a scanned document is only photos of the pages. It's a photo portfolio with text annotation. This (being photos) makes the document rather large, unless image compression is pushed to the absolute max, which makes it look ratty. If the document is over 100 pages it will also perform poorly on a portable device.

You are much better off developing a PDF by opening the document in the authoring application and going "Print..." "Save as PDF..." Because then you get a lightweight document that renders sharply at any zoom level, and is small because it is simply the text, formatting and fonts bundled together. This also means search and cut/copy work as the document author intended.

I was also set to purchase a book-cataloging system for the Md. Rail Heritage Library, complete with barcode reader and interface with the Library of Congress database, only to see it abandoned and orphaned by its developers just as I got the go-ahead from the board. All the pros in the field keep telling us to get PastPerfect software, starting at about $900, but that's for operating an entire museum system (including financials, maintenance, donations, membership, etc.)--for us, like getting a GE ES44AC to run a branchline excursion line.

And with "over 9000" customers as they say on their website, I too would be chewing my nails as to when the company just disappears. The litmus test for any software like that should be "Can you give me an XML file of my database?" And you should make that regularly and back it up. At WRM they used Filemaker Pro last I looked. It suffices, though an image feature would be nice.

This is relevant to my interests. When it comes to "Paper or digital?" my answer is a very firm "Yes."

Keeping the originals doesn't have to mean making them available for display or even use. It means making sure they're as safe as possible somewhere. Storage cost for them in a good facility is just part of the cost of doing business.

Yes. Housing them properly is the cheap part. The expensive part is "random access" i.e. wide aisles, deep drawers, painstaking indexing, careful refiling. As contrasted with records boxed, palletized, shrink wrapped and forklifted into a climate controlled container, which is effectively inaccessible.

The second is better. The documents are safer (less human activity, less deterioration, less fire hazard), and the digital scans you made provide vastly better random access and searchability.

As to the format, while text files are useful, I have been most grateful for those facilities that took time and effort to make .pdfs or other full views of their originals. Notes in the margins and ads on the side of the page are often a bigger story than the story.

Yes, that goes without saying. We must move past our "fear of every format" and embrace formats that are very simple (TIFF, GZIP, ZIP) or both open-standard and durable (JPEG, PDF, HTML, XML, etc.) and are likely to continue to be supported for a very long time.

In the 1940s, the city of San Jose's plan was to convert these documents to the hi-tech for the day...microfilm. ... the microfilming was done poorly with documents mismatched, unmarked and, at times blury… And the 5,000+ original documents?...Thrown into the trash.

Microfilming was done for ONE reason: to save space. It was not done to be "high tech", it was done because there was no other choice. There were no delusions that the quality was poorer. The documents would be otherwise lost because there simply was not room in a fixed size repository for the (even then) documents that were increasing exponentially.

Today, guess what can also grow exponentially? Seagate. At that point preserving the originals becomes less of an issue because storage can be off-site.
