Searching and Browsing
Searching by ISBN is usually the quickest and most accurate way to find a book. Our search function allows you to use this method to find a single title or to find all of your books at once. To search for multiple books, enter one or multiple ISBNs, separate them by a comma, space or return. (The ISBN is the 10- or 13-digit number on the back of the book cover.) You may also search by title, author, or keyword.
An ISBN is an International Standard Book Number. Every book sold anywhere in the world should have a unique ISBN, meaning you can find any book in the world simply with that one number. An ISBN number has ten or thirteen characters and is assigned by R. R. Bowker in the United States and by a variety of agencies worldwide.
An ISBN is usually located on the back of a book. It looks like this:
If the ISBN is not on the back of the book, you can look on the page in the front of the book that contains the copyright information
If you can't find the book you need, your book may be a course pack or is privately published. Please check with your professor.
Buying Books
We accept American Express, MasterCard, Discover, Visa, Diners Club, JCB, and purchasing cards.

Your credit card will be billed when we ship your order, generally 24 hours after you place it.
We know you need your textbooks as fast as you can get them. Choose Express Delivery as your shipping option and receive your books within 3 business days of their shipment. If you need your books even sooner, you can choose Expedited Delivery as your shipping option.
To find out when you will receive your item, you need to consider the availability of the item you ordered and the shipping option you selected. The equation we use is:
Available-to-Ship Time + Delivery Method Ship Time = Total Delivery Time

Orders placed after noon on Friday or at any time during the weekend will not be shipped until the following Monday. Please keep in mind that we do not ship on Saturdays, Sundays, or holidays.
When you successfully submit an order you will see a confirmation screen. You will also receive a confirmation email within two to three hours.

Textbook Rental
With our textbook rental program, you can rent thousands of textbooks, saving time and money. With textbook rental, you don't own the book, you are simply borrowing it from Barnes & Noble.com for a fee, and then returning it to us at the end of the rental period you selected.
To find textbooks available for rent, simply search for the book you are looking for, select the amount of time you would like to rent it for from the drop down menu, add it to your cart, and check out. Your book will be shipped to you, and you are free to use the textbook for the rental period you selected. At the end of your rental period, ship your books back to us (via FREE UPS Shipping) OR choose to extend your rental period or purchase your rental.
We offer very flexible rental periods up to 130 days. Please refer to individual Textbook pages for the rental periods. You have the option to extend or purchase your book anytime during your rental period.
All Rented Materials must be returned in salable condition. Salable condition will be determined by us in our sole discretion, but generally means:
- Book spine intact
- No excessive damage to cover or contents
- All original pages intact
- All original components present
- No excessive highlighting, writing or other markings
- Normal use highlighting and writing is permitted
Our damaged book guidelines can be found here.
We do not guarantee that access codes/keys/cards, CDs, DVDs, workbooks, charts or any other type of supplemental material will come with books rented. If a book you rent from Barnes & Noble arrives with a supplement, you are allowed to use it at no extra cost. At the end of the rental, all supplemental material must be returned with the Rented Materials.
Return shipping on rental textbooks is FREE using our easy-to-use UPS shipping labels. To do this, please sign in to your account and click on "My Account."

When you return your book, we check it out to make sure the next student can use it.

Obsessive-compulsive risks for teens.
Several factors have been suggested as contributing to OCD, including eating disorders, birth problems that subtly disturb brain development, and Tourette's syndrome (SN: 7/21/90, p.42). However, none of them shows a close link to OCD in the latest investigation, which tracked 930 boys and girls from birth to young adulthood.
"These findings suggest that clinicians should be aware of a risk for emerging OCD among young teenagers who have other [mental] disorders, especially depression and substance abuse," asserts Heidi M. Douglass, who directed the data analysis while a graduate student in psychology at the University of Otago Medical School in Dunedin, New Zealand.
Obsessions consist of repeated, distressing thoughts or impulses, such as the fear of getting contaminated by shaking hands with others. Compulsions are repetitive behaviors or mental acts intended to quell anxiety, such as washing one's hands over and over. Symptoms of the disorder take up 1 or more hours daily.
Douglass and her colleagues drew on an investigation of New Zealand youths that has already yielded clues to the origins of hard-core delinquency (SN: 4/15/95, p.232). Participants are mostly white and come from all social backgrounds. They have completed extensive medical and psychological testing every 2 to 3 years, beginning at age 3.
At age 18, 37 volunteers--4 percent of the total--cited symptoms of OCD that had occurred in the past year. That proportion coincides roughly with previous estimates of OCD's prevalence. The researchers compared this group to 590 teens who had had no mental disorders in the past year, 45 who had exhibited conduct disorder (frequent delinquency and violence) in that period, and 215 who had suffered from anxiety disorders or depression in the past year.
OCD cases typically involved either obsessions or compulsions but not both simultaneously. One or more mental disorders accompanied most instances of OCD, particularly depression, social phobia, and alcohol or marijuana dependence.
Only depression and substance abuse in early adolescence showed a significant elevation in the OCD group, compared to the other groups, Douglass and her coworkers report in the November Journal of the American Academy of Child and Adolescent Psychiatry.
Psychiatrists may need to devise a new diagnostic category that combines symptoms of OCD with those of mood disorders such as depression, the researchers propose.
Other proposed risk factors for OCD may apply mainly to the most severe cases, which have attracted the bulk of scientific attention to date, Douglass asserts.

Damage report
I've now clocked 23'000 km on the bike, and about 19'000 km on this trip, in 4 months. I'm happy to report that the bike has been running great until now, in fact just 3000 km back in Dubai I would have reported almost a perfect score, but I had to deal with a few problems recently.
I had the 10'000 km (8'500 km) service done in Istanbul, nothing to report there (except a hefty bill, but I need to keep the warranty running..). I also dumped the street tires and put TKC 80s on.
I had a minor crash when I tipped the bike trying to get back to the road on a very steep shoulder. That's where I bent the right-hand side pannier rack (Caribou cases). The thing is, one of the attach points on the right hand side, under the frame is through a 15cm long bolt. It's ok to hold a downward force, but when the whole weight of the bike acts laterally on it it can only bend. I haven't fixed it because it still holds and I'm afraid of making it worse by undoing it, and it's not easy to find a nice big long high quality bolt over here. I just had a welding on another point that was cracked. Oh, and the pannier latch bent as well, but I had a spare.
Then in the middle of Iran, on a gravel track in the middle on nowhere, the bike started to stutter and then stopped, as if running out of gas. I was thinking about my options and remembered the problems about the fuel pump controller. But when I opened the tank it made a suction noise: the breather hose wasn't doing its job. What a relief, I was back on the road in 2 minutes. I haven't researched the fault since it hasn't happened again since then.
Also in Iran (about 16'000 km) I noticed a slight leak on the left-hand side cylinder, at the valve cover gasket. Not too bad, just some sweat but still, for a 6-month old bike, that's pretty bad quality control if you're asking me.
In Dubai I went to BMW again for the 20'000 km service. I had the valve clearance checked and the brake fluid changed (I bought it with a dark fluid int he read break, as often reported, now it's back to normal). I asked them to change the gasket under warranty, but they had to order it and that would take 2 weeks. I didn't want to stay that long in Dubai so I gave up, I can live with it. I also discussed what looked like splashes of coolant on the cylinder, I noticed it in Iran but it hadn't happen again and the coolant level didn't move. They hadn't a clue.
I think those guys don't see a lot of bikes (there aren't a lot to begin with in UAE), and lack experience. Is it a coincidence that problems started to happen right after I left the workshop ? probably.
The brake pads were 2/3 gone so I bought some spares to change later on. I changed the tires again (the rear TKC was gone after 12'000 km), putting Karoo T instead.
The front rim has a nice dent, I had heard of the weak stock rims, so I0m not surprised but it's no problem so far. I haven't tried to bang it back in, I would probably make a mess of it.
So a pretty good picture really. Then in Oman, maybe 1000 km later, in a pretty tricky mountain road that I was doing in 1st gear, I noticed the bike overheating. It had never happened before, even in Albania where I rode in 1st and 2nd for long stretched and it was warmer than here. I had to stop a few times to cool it down. But as long as I kept the bike running at a fair speed, it wouldn't overheat. So I kept going for a few 100s km until I got back to Muscat. It was fine on the highway except for a somewhat higher fuel usage.
The radiator never got hot, even when the fan was kicking in, and the fan didn't help the overheating (read light on the computer). Note that the temperature gauge is a joke, it always shows about 2/3 whatever the real temperature, until it flashes when it overheats. So obviously the water wasn't circulating in the radiator. I hadn't read about a weakness in the water pump, but I was prepared to head back to Dubai (450 km away) for a chat with the BMW mechanic, but I first looked up the forums, where I found the instructions to bleed the coolant (thanks
Hello BMW, if that's something that happens all the time, why not put the instructions in the manual ? Anyway, I bought some coolant and it did the trick: now the radiator it's doing its job and the fan is blowing hot air on my pants.
Finally, almost simultaneously I had a blown headlamp and the 2 rear turn indicators stopped working (LEDs, so no blown lamps). I didn't mind the blown bulb, in fact there is no way to turn off the headlight and that's quite annoying as everybody is flashing their light at you because in these countries it is considered very wrong to drive with your lights on during daylight. But the indicators are more annoying, it adds to the safety while driving in the traffic. I had planned on those being the first parts to break after a crash, so it's not such a big deal, indeed I got rid of them altogether on my Tenere. That's probably the harness since both went off at the same time. Heck, with this central computer, I'm not sure I want to try and figure out what's wrong..
That's about it. No problem with the battery so far, and the chain and sprockets are running strong, no adjustment yet.
Oh, one last thing about the Touratech tank: it's doing its job fine, the only problem so far is the lid: it's leaking when the bike is tipped, and at the same time it has given me some trouble opening the lock. Lock ? why do you need a lock when there are quick release on the fuel lines sticking out from it.. in fact it's those quick releases that worry me most, but so fat they're doing fine. The tank also acts as a protection for the radiator when I drop it, which has happened a few times already.
I just hope I will be able to say as much when I reach Capetown! (next BMW dealer)
