Digitizing Your Dead Trees? 367
smart2000 asks: "I'm tired of lugging around dead trees. I've just moved offices and had to move over 100 pounds of 'essential' technical books. It is clear to me that the dead tree industry is never going to supply the books I want in electronic form, so it's time to do it myself. What hardware and software should I use?"
"The Plan: Take the binding of each book and cut it off. Feed into a scanner with duplex and cut-sheet feeder. Scan as a 300 DPI jpeg with compression. Then OCR them overnight. I don't expect the OCR to be perfect, just good enough to use as a searchable index.
What are the suitable scanner choices for Linux? Any recommendations for OCR software that will write in an open format? Has anyone done this before?"

Adobe Acrobat (read $$$$) does all of this and works well. But if you are *nix person you could pipe some ghostview tools together and put it all into LaTex then re-export it as a digital book in to PDF. Scanning: look no further than a HP scanner. It doesn't even have to be HQ unless you need the diagrams to be photoquality. After that burn it all to CD or, better, DVD.

jpeg also sucks for this. Jpeg is best for full color images like photographs. Better off using tiff or png. Most OCR software will require tiff. Don't know of any OCR software for linux although you might get some windows app to work under WINE. Textbridge from Xerox isn't bad for the money.

I bet about half of your books are already online.
Also, for your compression you should NOT use JPEG. JPEG is optimized for smooth tones and will badly blur hard edges like text. On the other hand, JPEG performs relatively poorly at compressing large areas of the same color (i.e. white backgrounds.) [Note for the nit-pickers, both of these JPEG issues will be reduced/eliminated in JPEG2000.]
I scan documents to either compressed TIFF (tend to be large), PNG, or (*shudder* [unisys.com]) GIF.
From the Project Gutenberg "Making Etexts from Paper Originals" paper" [promo.net]: (You can bet these guys know how to scan...)
I suggest never using JPEG. The quality loss for printed words is just terrible relative to the compression you get. Also, just substitute PNG for GIF and the above works.Re:Go To Kinko's!!!! (Score:1, Informative)

Where I work we tried to turn a book into PDF that we no longer had an electronic copy of. Keeping the images up front with ocr text behind, about 300 pages alltogether. Even with max compression, and the lowest acceptable DPI (300 I think), the PDF came out to 95MB. It didn't help that we scanned the book page by page and generated the PDF by hand, on a slow hp general consumer model scanner, either. (the initial pdf took over 120hrs to produce, with rescans and ocr'ing and everything).
We wound up taking the acrobat ocr'd text (it was better than the off the shelf ocr package we had at the time) via the adobe accessibility website, and fixing it up. It was a pretty big project.
We recently hired a document imaging company to PDF a lot of smaller historical documents for us, and that has worked out well. It's kind of pricey, but we also paid them to proof the ocr behind the images, and to hand adjust the images for appearance. It's worked out rather well.

Several shell scripts to scan various types of books. It's amazing the page numbering schemes some publisers use. With this setup I can scan approximately 2-3 college textbooks 1000 pgs.(grayscale) or 1 color in an 10 hour period. (including checking for bad scans, sane ain't perfect, so you better check em) also jpg isn't very good for OCR, I store as png, and convert a second set to jpg for web viewing. OCR under linux isn't quite there yet (unless you want to pay through the nose) So I am Archiving the pngs to CD until it is. This also allows me to regenerate the jpgs if I lose a webserver disk.

Second, I'd make them HTML/PDF instead of plain text. Mainly because then you can retain the fonts. (Of course, some of the OCR programs will do this for you if you want to save it as MS-Word file but that's another story.
Fourth, a well scanned book is just as easy to read as the book itself. Honest!
Last, use an exacto knife to do the cutting and a good ruler with a metal edge. Exacto + wooden ruler means lots of splinters, badly cut pages, and sore thumbs/fingers.

The National Archives and Records Administration [nara.gov] has a FAQ [nara.gov]. Their advice on preserving family papers? --
Paper preservation requires proper storage and safe handling practices. Your family documents will last longer if they are stored in a stable environment, similar to that which we find comfortable for ourselves: 60-70 degrees F; 40-50% relative humidity (RH); with clean air and good circulation. High heat and moisture accelerate the chemical processes that result in embrittlement and discoloration to the paper. Damp environments may also result in mold growth and/or be conducive to pests that might use the documents for food or nesting material. Therefore, the central part of your home provides a safer storage environment than a hot attic or damp basement.
Light is also damaging to paper, especially that which contains high proportions of ultra violet, i.e., fluorescent and natural day light. The effects of light exposure are cumulative and irreversible; they promote chemical degradation in the paper and fade inks. It is not recommended to permanently display valuable documents for this reason. Color photocopies or photographs work well as surrogates.
