I've been scanning my (several thousand books) for over a year now. Using a flatbed scanner is completely impractical at 1 minute per page. I:
1. Use a stack slicer to cut the spine off
2. Feed it through a sheet feeding scanner
3. Check results
4. Do any necessary rescans and stitch the result together with pdftk
5. Chuck the (now destroyed) book into the recycling bin
I have around 60Gb of books now, and have emptied many, many shelves and boxes. It's nice that I can now put my entire library onto my laptop.
It doesn't take that long per book, maybe 5 minutes. The main time-wasters are when a book has damaged pages so the hopper feeder doesn't work right on it, or when the bookbinding glue has spread too far and pages are stuck together beyond where the spine cut was made.
The hopper scanner will scan both sides at once in a couple seconds.
I run the scanner at 400dpi, which is far better than any of the current ereaders will display them. But I figure it's future proofing them. My current ereader of choice is the Kobo Aura that has the retina e-ink display. It's well suited to reading scanned books because:
1. the retina display eliminates the jaggies
2. the glow screen works well in low light conditions
3. the larger screen size is suited to scanned book pages
4. the 32Gb microsd slot enables me to carry around at least half of my library :-)
Probably not the place to ask, but what do you need them for? I think there's still places that sell books by the yard. You can also try estate/yard sales, and just offer ten bucks to haul all of their books away.
That's how I buy a lot of my books currently (estate sales, library clearance, etc) but regarding the sliced pages: I have a very large personal library that can't be damaged or marked up for a variety of reasons. It just so happens that I have three uses for well-sliced pages of (preferably) interesting books: for sculpture, for rebinding practice (what better source for testing out different glue mixtures or techniques), and lastly to spiral bind a few into markable workbooks (I used to do this with tattered textbooks and then give them away). I can't really go into it from my phone, but suffice to say I have a soft spot for recycling old books and see it as a possible opportunity to find a non-standard selection.
Edit: Also, if someone is just throwing them out that saves me money and therefor time trying to decide what to take.
As an experiment, I took a carton of books to Half Price. They went through them, and offered to buy 3 of them for a few dollars. The rest they said they'd take for free, but wouldn't pay anything for them.
They had limited shelf space, and the books that didn't sell quickly went to the recycler.
The problem with selling books on Amazon is if it, plus packaging, is over 13 oz, you have to take it to the post office. This, of course, destroys any economic or environmental benefit to selling them for less than 15 or 20 bucks.
Very, very few used books are worth that much. I do have some, and they've sat for sale on Amazon for over a year. Books less than 13 oz I'll sell for a few bucks on Amazon, but they rarely sell, either.
So I cut & scan with no guilt about destroying the books. It's sad, but they are worthless.

It's clear that a lot of Amazon book sellers don't value their time as highly as you do. They're sitting on a lot of warehoused books and basically making their money off the difference between media mail shipping charges and the standard cost of shipping on Amazon.
Most business level copy machines will quickly scan hundreds or thousands of pages, both sides, and assemble into a PDF. If I was going to do this, yes, I would slice the spine off and either scan at work or rent a machine. I don't have any rare books. Just books I've collected over the years.
Unfortunately most of them are art/architecture books. I'd really like to have very high res original source ebooks. By very high-res I mean I'd like to have say 300dpi or higher at the size of the book or larger. I'm imagining having full color e-ink or some other awesome tech in the next 10 years that lets me view large coffee table art books at their original size or larger and unfortunately I think scanning them, even in high-res would not really do them justice.
Imagining full wall displays it would be awesome to be able to view architectural pictures wall size and not have them look lo-res and blurry.
Is there any benefit to cutting the spine vs using heat to loosen the glue and remove the pages manually?
I have been doing this with old video game strategy guides for about 6 months now. To me it provides a better solution because I still have the spine and all the content which is printed very close to the book's seam. It does take a LOT longer to scan page-by-page, but I also get to keep the single pages instead of throwing them away.
I have also tried using an exacto knife but the results aren't as clean. I am still waiting for a better solution and your comment certainly does make me think.
Cutting the spine is quick and easy. Even if you remove the glue by some method, the pages are still sewn together. I have thousands of books to go through, so being fast is important.
Yes, it can be a problem with some pages that are printed very close to the spine. I keep an eye out for those and handle them separately. That's usually only an issue for paperbacks from the 50's and earlier.
I've found that regularly wiping down the rollers with denatured alcohol seems to "restore" them, so no, I've never replaced the consumables, and I've run hundreds of thousands of pages through it.
The real problem is dirt gets behind the glass window and makes streaks on the scan. It's all sealed up and I can't figure out how to get behind it and clean it.
The other thing is, you can often find lightly used models on ebay that are cheap because they are missing things like the tray, hopper, and power brick. Just get one of those, and move over your other parts to it, and you've essentially got a new one ready to rock.
I just love having all my books searchable, I use http://1dollarscan.com/ quite regularly for this purpose. It keeps these things really simple, esp. because it still takes me with regular book scanners (the non fully-automated ones) about half an hour scanning a 300 page book.
I'd never heard of them before. I wonder if they keep the old scans and resell duplicate books. They could make a bunch of extra money on half.com or similar. Depending on how they're scanning the books it'd also save time. Then again, it could be that they're required to destroy the scanned book in order for it to be legal.
The process to digitise it they use ends up partially destroying the book; at least, it removes the spine ("step 2" of http://1dollarscan.com/works.php). They do mention that they keep the book around for 2 weeks (to allow rescans) but then they recycle it.
However, doing some more research, it seems that for certain items they can return it:
Q. Are books ever returned?
A. First of all, please understand that we do NOT return
any books after they are scanned. The books are recycled
after they are cut and this is part of our operation
The exceptions for returns are for photos, material you
wrote yourself, material you own the copyright to and
only a few more. If one of these exceptions or a similar
exception applies to your order and you want the items
returned, then please purchase a return option($5) at the
time of your order.
Really wish this was around elsewhere. Apparently no such service exists in the UK, so when I purged all my dead trees, I just scanned the bar codes as I didn't have the time to scan the whole books (or figure out how to automate it).
I often buy books directly from amazon.com (even used ones) and get the seller to ship them to 1$scan. By creating an account you get a personal ID and as long that is visible on the address label the book is filed under your account.
Partially OT: For people using Canon compact cameras together with the CHDK firmware in DIY imagers/scanners, which models are preferred these days? My A640 was stolen and I've been wondering what to replace it with.
