Portable Scanner Solutions for Research?
Fished asks: "Lately, I'm finding that I need to do a lot of research in Libraries -- remember those? I'm tired of feeding dimes to the copiers, and would like to buy some kind of portable scanner to go with my Powerbook. Unfortunately, I can't seem to find one that will work. Back in the eighties, this were as common as dirt: they were small, four inch wide scanners that you could run over the page. Also, while I've found three portable scanners for PC's (from Antec and Pentax) even if I could somehow get them to work with Mac OS X, they are sheet-fed, which is useless for scanning pages out of books. Does anyone still make the old-fashioned Hand Scanners, and do they make them for Macs?"
Several years ago, HP ha a product called CapShare. A really cool handheld scanner that has an on-device LCD screen that you can perform simple functions like editing, rotating, etc. with. You can then transfer via infrared to your laptop or, better, to a printer! Unfortunately, this product has now been discontinued. I used it for a while, and it was great, except for one thing -- most of the pages that I need to scan from the library are bound -- and the words near the spine tend to become unreadable...
Ah, yes, the digital version of the Hogan's Heroes approach.
Handheld scanners were useless for scanning books. Most books are too wide for a handheld scanner and you have to stitch together your scans - a VERY awkward process. And even if you can scan the whole width of the page, the roller used to detect when the scanner was moving would go off the bottom of the page of the book before you scanned the final line of text!
In short - forget about the handheld scanner idea. They do sell line scanners that read in lines of text at a time if you just need short segments. I suppose you could even take pictures of the pages with the new high megapixel digital cameras.
If you put the scanner at the edge of a table or desk, you can scan pages of books quickly and easily with less distortion than you'd get from a hand-scanner. This may help make up for the slightly less convenient form-factor.
Try the discount/clearance table at your local Office Depot / Staples / Office Supply store. I always see "clearance" scanner there.
I've not actually tried this with my TiBook, so YMMV.

Canon make USB powered scanners. They are slim and would easily fit in a briefcase. There are OS X drivers available. I've got at a CanoScan N670U on my iMac and it works fine. There is X OCR software available but I don't have any.

I've used (and use) the HP Capshare but I find it too badly designed, ergonomically and electronically (almost a study in bad design), to make for pleasant scanning. Nowadays, I generally use a Sony Vaio notebook and a USB scanner, a CanoScan 670U. The Canon scanner is powered via the USB 1.1 port so I needn't bring a brick to the library, and I can choose exactly the type of scan necessary for the material I'm using (everything from B&W text through 600dpi full color). I don't think the scanner weighs two pounds, it's only about an inch thick, and the scan area is 8.5"X11". And it cost under a $100 at CompUSA.
yes, i've done this as well. 1600x1200 is way more than enough for a page of text. I haven't tried running the image through OCR software, but given that canon has twain "scanner" drivers for their cameras i'll bet it would be easy.
For glossy paper and to avoid annoying the others around you it is best to not use the flash. if you're in a low light situation, get a small tripod and a book stand.
For a very good affordable 2mp camera today i recommend the canon powershot A40; search on my simon for good prices. Any 2mp camera will probably work for your needs; but why buy a crappy one?
Some of the thin Canon models (n656U, n1220U, LiDE 20, etc.) are overall about the same size as a PowerBook, and they draw their power from the USB port; no need for a wall wart. No OSX drivers for the earlier models though...poke around Canon's site for details on what's compatible.
Scanning is slow though...I have to agree with others suggesting just using a digital camera of sufficient resolution.
"they are sheet-fed, which is useless for scanning pages out of books"
Not if you tear out the pages, first.
I understand and appreciate your problem. I have tried many solutions, and I believe the c-pen 800c is the best solution I've tried for my research needs. There is another pen based solution, WizCom QuickLink SuperPen which I've also tried. I did not like the wizcom because it was not as comfortable to use or as accurate. It also actually had a moving part. :) Both have SDKs to write your own software, however, the only one I could get access to was the c-pen, which made it even more of a favorite of mine. The cpen can also act as a mouse and can do some gestures in addition to being able to input text through "writing" (in big letters) on the page. Both companies are barely alive it seems, but it's a niche market, and I hope they survive. They both have some fantastic functionality, such as translation and barcodes. Of course c|net did the normal bribed review, but I guess the cpen wasn't out at the time. Both are upgradeable and can load extra programs or dictionaries and such. I wouldn't want to go back to college with out one.
Hey, if this has at all been useful, please feel free to buy me one! I miss having it around.

A) NASA didn't invent the pen, Fischer did, and sold it to Nasa, and it didn't cost Billions.
B) Pencils are terrible in space, all the little graphite dust gets into the electronics, causing shorts. Not a good idea on a space craft.
NASA never asked Paul C. Fisher to produce a pen. When the astronauts began to fly, like the Russians, they used pencils, but the leads sometimes broke and became a hazard by floating in the [capsule's] atmosphere where there was no gravity. They could float into an eye or nose or cause a short in an electrical device. In addition, both the lead and the wood of the pencil could burn rapidly in the pure oxygen atmosphere. Paul Fisher realized the astronauts needed a safer and more dependable writing instrument, so in July 1965 he developed the pressurized ball pen, with its ink enclosed in a sealed, pressurized ink cartridge. Fisher sent the first samples to Dr. Robert Gilruth, Director of the Houston Space Center. The pens were all metal except for the ink, which had a flash point above 200C. The sample Space Pens were thoroughly tested by NASA. They passed all the tests and have been used ever since on all manned space flights, American and Russian. All research and developement costs were paid by Paul Fisher. No development costs have ever been charged to the government.
Because of the fire in Apollo 1, in which three Astronauts died, NASA required a writing instrument that would not burn in a 100% oxygen atmosphere. It also had to work in the extreme conditions of outer space:
1. In a vacuum. 2. With no gravity. 3. In hot temperatures of +150C in sunlight and also in the cold shadows of space where the temperatures drop to -120C
(NASA tested the pressurized Space Pens at -50C, but because of the residential [sic] heat in the pen it also writes for many minutes in the cold shadows.)
Fisher spent over one million dollars in trying to perfect the ball point pen before he made his first successful pressurized pens in 1965. Samples were immediately sent to Dr. Robert Gilruth, Manager of the Houston Space Center, where they were thoroughly tested and approved for use in Space in September 1965. In December 1967 he sold 400 Fisher Space Pens to NASA for $2.95 each.
Lead pencils were used on all Mercury and Gemini space flights and all Russian space flights prior to 1968. Fisher Space Pens are more dependable than lead pencils and cannot create the hazard of a broken piece of lead floating through the gravity-less atmosphere. http://www.snopes.com/business/genius/spacepen.ht
At least, in Pennsylvania.
Recently my wife did some geneaology research in Pennsylvania for my mother-in-law. She intended to use her digital camera instead of feeding the copy machines, but all of the libraries, record archives, and courthouses she visited refused to allow her to do so, and even required she sign an agreement stating she was familiar with the rules of the place, all of wihch were about how she could not use scanners, cameras, or other copying mechanisms other than the copy machine provided by the library.

I have one which I'll gladly sell to you. :-)
That having been said, get a Logitech QuickCam 2000 (or QuickCam Pro). It's USB, it's small, it's a good resolution, it comes with a small desktop tripod. The advantage is that in addition to using it to take pictures of printed matter, you can use it to take pictures of the microfilm reader displays. You can't do that with a scanner. It paid for itself twice-over when I did a research project two years ago. On the downside, however, it doesn't work with Linux (AFAICT) or MacOS.
