lesinator writes "On Monday the 28th the US Library of Congress is holding the eighth lecture in its series on Managing Knowledge and Creativity in a Digital Context. Previous speakers include David Weinberger on blogging, Brewster Kahle - founding member of archive.org and the wayback machine, and Lawrence Lessig on intellectual property and the creative commons. After the lecture questions will be taken from the audience and the internet. C-Span will be broadcasting the lecture live at 6:30 PM EST, and also has archives of previous lectures.

      While it's an interesting question, it really depends on how you want to store the contents of each book.

      Would you store each page of each book as an image? As flat ASCII text (except of pictures and diagrams, of course!)? What kind of indexing would you do? Basic indexing of book names? Full-text indexing of the contents? All that storage adds up!

      In summary, the library of congress (depending on the method used) could probably fit into something ranging from a couple of gigabytes to a couple of petabytes.

        Well I owuld think that they would have to start with an image first. Once they OCR'd it and generated ascii text files, they could save a tremendous amoutn of space by simply deleting the images. However, after that much effort in imaging all those pages, I just can't see them doing that. The best bet is probably two databases, one of ascii text and one of images.

        They might even be able to generate revenue by having the ascii text freely available and searchable, while the images would cost money. That way folks just interested in the text can find it easily, while scholars and others who need to see the source material can have access at a moderate price.

          You're making a large number of assumptions in your first paragraph:
          1. The OCR is always correct.
          2. The documents could be represented in ASCII
          3. The text is the only part of the document with any value

          Of course, your second paragraph shows that clearly those assumptions can't be true -- why would someone pay more for something without an additional benefit?

          And you wouldn't maintain seperate databases -- pictures aren't searchable. You'd want to use any OCRd (preferably vetted afterwards) as the basis for inde

If you want to read Moby Dick, you can do that in just a text format, you don't have to view the actual images (which are significantly larger files). If, on the other had, you are doing your doctorate thesis on Moby Dick than you will likely want to view the actual images.

        • Mmm. I've seen document archival formats available (patented, I think) taylored for printed documents -- using one of these, it should be possible to get your typical page well below 100K, and stay in that general range even with drawn illustrations (though anything w/ color or photo-style images is no longer suitable). DjVu is a prime example of these, though others exist.

          So keeping the scanned images shouldn't really require such a tremendous amount of space.
      • Uncompressed text, maybe markup, and you're looking at about 20 terabytes I believe. Adding in the works with either illustrations or photographs, in some decent but lossy compressed format, and you're easily quadrupling that (just a guess).

        Indexing, by what, subject, author, and title? 1% overhead at most. Fancier googlesque searching though, could be a big hit.

        And correct me if I'm wrong, but there are quite a few videos too.

        A couple of gigabytes?! Only if you burn it first. There's something like 10^8 books, nevermind the other stuff. How do you compress any given book into 100 bytes?

        The "20 TB" figure comes from the smallest possible measure, treating the flat books as ASCII text. Even just considering current digital content, it's also inaccurately small by >1 order of magnitude.

      Well, I would imagine that unless they have a massive staff and many OCR scanners or automation with REALLY good OCR, this may take a LOONNNG time.

      I'm not quite sure about the length of a BLOC, but this is a job for not-quite-manual labor. Each book requires a simple task: Scan page 1, flip page, scan page 2, page 3, flip, ad infinitum.

      One way to save on time would be to contact the publshers of any book made after 1985-ish, where you can get electronic copies from the author. Some older books may have been already digitized, but it's still going to take more than 25 years unless there's a massive army working on this.

        Nonsense. I put together solutions with high-speed scanners all the time. Some of our highest-end average 118ipm (Duplex) and have 1000pg ADFs.

        Also, you would generally split the load between 4-6 of these scanners for a job this big. The software is automated, and will OCR/Convert/Archive the file is one step.

        As a general rule, you can fit 10,000 b/w text pages in 1GB of storage.

          • Nope, Canon (and others) make Book Scanners with actually flip and scan each page automatically. They can handle all sizes too.

            They are very expensive, but cool as hell.

          • I used to work in that industry too. Typically, bound material would be cut into loose sheets... you basically sacrifice a book to get the images electronically. Also, any decent high volume scanner can scan both sides of a sheet at once, so there's no flipping.

            As an unrelated asidem some even scan in color, but your storage requirements go way up if you do anything other than bitonal (even greyscale eats up the bytes pretty quick).

          It's been continually re-written. For example, until 1954 Jesus never actually said "I am the Son of God"; when Pontius Pilate accused him of claiming to be the Jewish Messiah, he cryptically responded "It is you who said it." The fact Jesus didn't claim to be the Son of God but was surrounded by intense believers was one the essential "mysteries" of Christianity that you were supposed to accept as a Christian.

          In 1954, the American "New International" edition just editted the trial dialog and "re-interpreted" "it is you who said it" into "I am the Son of God." I don't think the European and Catholic churches have editted that part yet.
