In one sentence, describe what the following article is about: There's a lot of advertising and spam for sites that promise to provide free books, but there are a couple reliable, long-lasting sites that provide extensive free collections.   Project Gutenberg hosts a large volunteer-provided collection of books without U.S. copyright protection, usually because the author died more than 70 years ago. All of them are free, almost all of them are available in plain text for any computer, and many are available in eBook reader formats as well.   Google Books has an extensive and varied collection, but not all of it is fully available or free. Books under copyright protection usually only have a few pages displayed, but sometimes there is a link provided for purchasing the full version. If you are studying an academic subject, or are interested in historical works, books in these fields may be easier to find online than in physical form. Take a look at the following free, specialized collections:  Use the HathiTrust website to search for books in many academic collections, including many free eBooks. Some materials, but not all, are restricted to members of universities or other academic institutions. A large collection of classical Greek and Roman literature is available through Tufts University's Perseus project. The Library of Congress has an online collection of rare historical documents and a few other old books that can be difficult to find anywhere else. Companies that sell eBook readers often have their own collection of eBooks, including free options. If you do not have an eBook reader device, you can download a free program to access the Kindle collection on your Windows or Mac computer, or use a non-proprietary database such as FeedBooks by installing Adobe Digital Editions for free. Apps are also available for most eBook databases in the app stores of all major phone and tablet manufacturers. If you are trying to track down a specific book, and it is not available in any of the above collections, an online search may locate it on another website. Keep in mind that most recent books are not available for free, although some publishers offer a free or discounted eBook if you already own a paper copy. Be cautious about any website you do not recognize as a well-known, trustworthy source of books. Try searching for reviews of the website before you download anything, and never enter your credit card information for a "free" eBook.
Summary: Browse a collection of free books. Find rare, historical, or academic books online. Browse free books on an eBook database. Search for a specific book online.

You want your candle to be small enough to float inside your jar. Your jar should also be large enough to hold some herbs and citrus slices. Fill your jar about ¼ of the way with some fresh herbs. Consider using some herbs that repel insects, such as: eucalyptus, lavender, lemon, peppermint, or pine. Take some lemons and/or limes, and cut them into thin, even slices. You want the slices to be ¼ to 1 inch thick. Cut enough citrus to loosely fill your mason jar. Pour some cool water into the jar. Leave an inch or two of the jar unfilled. Add about 10 drops of citronella essential oil into the water and stir to blend it. You can use more or less citronella essential oil depending on your preference. Gently place the candle on top of the water in your jar. If your accidentally gets wet, do not worry. Either wait until it dries out, or dab the water off with a tissue, que-tip or cotton ball. To use your citronella candle, simply set it on a stable surface and light the floating candle. The citrus and herb water will keep for a few days, but eventually you will have to discard it. Consider placing a lid on the jar and storing it in the fridge when you are not using it to help keep it last longer.

Q: In general, signs of tapeworms can be difficult to spot. The most obvious sign is when you spot little segments of the worm - almost like grains of rice - around your pet's anus or in its fecal matter. Sometimes, behavioral clues might tip you off. If your dog seems to be dragging its butt on the carpet more frequently, you may want to check for tapeworms. It is possible that the dog's anus is irritated - hence, why it would rub its rear-end on the floor. Anemia occurs on rare occasions too. The veterinarian may want to verify the presence of tapeworms before a prescription is given to you. The best way to do this is to take a plastic bag and to collect a specimen. Don’t make physical contact with the worm. Just scoop it up and put it in a bag. In other cases, you might have to pick the worm segment off of your dog’s rear-end. Otherwise, your veterinarian may ask to keep your pet for a couple of hours to collect a specimen for himself. They'll either insist you come in for a check-up, prescribe you a medication over the phone, or direct you to an over-the-counter medication sold at most pets supply stores. There are a variety of medications — most of which use praziquantel — to combat these little wormy parasites. The most common medications are Droncit, Drontal Plus, and Tradewinds Tapeworm Tabs. These can be found at vet clinics and some pet superstores.Your vet will know exactly which treatment will best eliminate tapeworms. Depending on your pet, your pet’s size, and your pet’s age, your vet will take differed medicinal approaches.  If you purchase a dewormer at a pet supply store, be sure to follow the directions methodically. Most treatments are given orally, but there are injections and topical treatments too. All of these medications will have age and size specifications that you’ll need to follow. For example, most medicines cannot be used on young kittens (less than 8 weeks) or kittens under 2.2. lbs.
A: Look for common symptoms. Collect a stool sample. Call your vet. Follow your vet’s instructions closely.

Problem: Article: Use a handheld vacuum to suck up dust particles on the outer section, or inlet ribs, of the box fan. You can also use a feather duster to wipe away dust or dirt.

Using water on the blades is okay, just make sure to dry them off. If your fan was in a greasy environment like a kitchen, you can use a mild soap to wash the blades.
