In one sentence, describe what the following article is about: Federal law requires the college to provide you with a list of required textbooks once you register for classes, so you should be able to find out which books you need well in advance from either the registrar or your professors. You should not need to rely on the campus bookstore to tell you. You might be able to find the occasional good deal at your campus bookstore, but in the vast majority of cases, you can find the books you need for a much lower cost somewhere online. Check out websites like BIG WORDS.com and Campus books.com, both of which direct you toward textbook sellers offering the lowest prices. Also check out websites that allow users to sell their own used and new copies of a book, like Amazon or Half.com. For many textbooks, you can buy an old edition at a lower price without facing too much difficulty. You might want to check with your professors before doing this, however, in the rare instance that there is a significant change in the new edition that you will need access to in order to survive the class. Renting your textbooks will not guarantee a lower price tag, but oftentimes, the price to rent a book will be cheaper than the price to buy. Look into both options and determine which will work best for any particular book. You can check your campus bookstore for renting opportunities, but there are also online sources, including Chegg, BookRenter.com, CampusBookRental.com, and ValoreBooks. If you really want to pinch pennies, you can check for coupons that allow you to save money on textbooks bought online. These coupons will rarely be specific to the publisher, but you might be able to find coupons for various online stores. If you know a friend who needs to buy some of the same textbooks, consider splitting the cost in half with that friend and sharing the book. Upperclassmen who are done with a textbook for good will occasionally sell it, and the cost is usually pretty cheap since they tend to be more interested in making whatever they can on the book. As long as the international edition is printed in the same language, this can be a viable option. Research carefully, however, since international editions can go either way in terms of cost. Check the cost of shipping, as well, since shipping costs on international editions can sometimes cause the overall price of the book to shoot up.
Summary: Get your textbook list straight from the source. Skip the campus bookstore and shop online. Consider an old edition. Rent your textbooks. Check for coupons. Share the cost with a dependable friend. Buy from upperclassmen. Check the cost of international editions.

In one sentence, describe what the following article is about: It can be easier to get a piece of jewelry authenticated if you can find a signature of the designer somewhere on the piece. Many designers leave something like their initials engraved in a piece of jewelry, so scour the piece for any markers of the designer. There may also be hallmarks left on the jewelry. These are stamps left by a specific company. For example, Cartier jewelry is stamped with an eagle head. If you can designer signatures, this is a good start. However, more information is needed. There are forgeries in the jewelry world, so a stamp or signature may not be enough to authenticate a piece. Cut, clarity, carat, and carat weight are referred to as the 4 C's of gemstone certification. This information should be included on a certificate of authenticity, as it can help assess how much the piece is worth. Take your item to a local jeweler for appraisal. The cut refers to the shape of the gem, as gems and diamonds are cut into a variety of shapes. The clarity is the gem's purity. Diamonds, for example, are easier to see through when they're purer. Diamonds, and some other gems, are graded on color. In general, less color variation means the gem is worth more. Carat weight refers to the weight of the piece. Heavier jewelry is generally worth more. It's vital to work with the American Gem Society (AGS) at some point when authenticating a piece. You should hire an appraiser associated with the AGS to examine your piece. You can find a legitimate authenticator in your area through the websites of the AGS. There is a search tool where you can look for reputable appraisers in your areas. Not all appraisers will provide you a certificate. However, having an appraisal and confirmation of a piece's legitimacy from an AGS appraiser is important. You may have to hire a private authentication company to issue the certificate, but information from a qualified appraiser should be included. This can help your certificate look professional when you try to sell your jewelry. When working with an authentication company, make sure you include all the necessary information. Do not work with companies that hand out certificates lacking certain details. Your certificate should include the 4 C's of your jewelry, and verify the diamonds or gems used are legitimate. The certificate should also include the origin of your gemstone. For example, it should say whether it was made authentically or found. It's very important your certificate include all this information. Buyers and dealers do not work with sellers that cannot provide legitimate certificates of authenticity.
Summary: Look for designer signatures. Have the item examined by a jeweler to determine its cut, clarity, carat, and carat weight. Have a certified gemologist appraiser or independent certified gemologist appraiser of the American Gem Society appraise your jewelry. Check that your certification of authenticity is legitimate.

In one sentence, describe what the following article is about: If your excess facial sweating disrupts your daily routine or causes social withdrawal or emotional stress, contact your doctor. Your doctor will ask you about your symptoms and medical history in order to make a diagnosis. Your doctor may also run urine, blood, and other lab tests to determine if you have primary or secondary gustatory sweating. Primary gustatory sweating is caused by damaged nerves, while secondary gustatory sweating is caused by an underlying medical condition like diabetes. Apply the antiperspirant to your clean, dry face in the morning and before you go to bed. Rub it into your skin along your hairline near your forehead, temples, ears, and neck. Before applying the antiperspirant, test it on a small area of your skin first to ensure that no irritation occurs. Ask your doctor for advice about which antiperspirants work best for gustatory sweating. There are prescription-strength topical creams that can be used to effectively control gustatory sweating. The most common is called glycopyrrolate cream. Talk to your doctor about whether this could help limit your sweating. Talk to your doctor about how often you can use glycopyrrolate cream. Typically it is used once a day, although it can be used twice a day in extreme cases. There are no known side effects for this medication. Oral anticholinergics, such as oxybutynin, propantheline, and benztropine, are also used to treat gustatory sweating. Anticholinergic medications are systemic medications that block the nerves that are signalling your body to sweat. Take the medication per your doctor's instructions. Side effects associated with anticholinergic medications include dry mouth, blurry vision, and impaired taste. If you are an athlete or someone who works outdoors, talk with your doctor about ways to prevent heat exhaustion, since anticholinergic medications decrease sweating.
Summary:
Set up an appointment with your doctor. Use an over-the-counter or prescription-strength antiperspirant. Try a topical face cream. Take an oral anticholinergic medication.
