In one sentence, describe what the following article is about: List the name of the author in "last name, first initial" format. If there is more than one author, list subsequent authors in regular "first initial last name" order. Place a comma between author names, and use the word "and" before the final author in a list.  For example: "Bass, Len, Paul Clements, and Rick Kazman." With multiple authors, list them in the same order as they appear on the title page of the book. Don't list more than 7 authors. If there are more than 7 authors, include the names of the first 7 followed by the abbreviation "et al." An eBook may be published at the same time as the original book was published. However, for older books, the eBook edition typically comes out later. For Chicago style citations, you need to use the original, copyright date found on the title page. For example: "Bass, Len, Paul Clements, and Rick Kazman. 2003." The title of the book follows the publication year, and should be italicized. Capitalize the title exactly as it appears on the title page for the book. If there are multiple editions of the book, list the edition you used after the title. Don't italicize the edition. For example: "Bass, Len, Paul Clements, and Rick Kazman. 2003. Software Architecture in Practice. 2nd ed." The next part of your Chicago citation provides your reader with the location where the book was published and the name of the publisher. Include enough information to correctly distinguish the location. Leave off words such as "Inc." at the end of the publisher's name. For example: "Bass, Len, Paul Clements, and Rick Kazman. 2003. Software Architecture in Practice. 2nd ed. Reading, MA: Addison Wesley." The final part of a Chicago citation provides details on the format of the eBook and where or how you accessed it. If the eBook can be read through a device, such as a Kindle, you would list that. If you accessed it online, provide a direct URL to the book. For example: "Parpart, Jane L., M. Patricia Connelly, and V. Eudine Barriteau, eds. 2000. Theoretical Perspectives on Gender and Development. Ottawa, Canada: International Development Research Centre. http://www.idrc.ca/en/ev-9419-201-1-DO_TOPIC.html." If so, include this number at the end of your citation. You can typically find this number on the title page of the eBook. It will begin with "10" followed by a 4-digit prefix, then a slash and unique suffix numbers. With Chicago or Turabian style, you may use footnotes or parenthetical in-text citations, depending on the requirements of the class or program for which you're writing your paper.  Footnotes contain basically the same information as the full citation, except that the first author's name is listed in regular order (first name last name) rather than last name first. For parenthetical citations, list the last name of the author or authors followed by a comma and the year of publication. For example: "(Bass, Clements, & Kazman, 2003)."
Summary: Provide the name of the author. Include the original date of publication. List the title of the book. Provide publication information. Include information about the source of the book. Some eBooks have a digital object identifier (DOI) number. Use the author-date system for in-text citations.

Problem: Article: Before you fill up your backpack and start wearing it, you will want to properly adjust your backpack.  Adjusting your backpack can help make it more comfortable and help prevent injury.  Make sure your backpack fits properly before you start regularly using it.  Most backpacks will have an area on the straps that you can use to adjust the length of the straps themselves. Pulling more or less strap through the buckle will adjust how long the straps are. Adjust the straps of the backpack until it fits snugly against your back. Avoid leaving too much slack in the straps of the backpack as wearing the backpack too low can hurt your back. Make sure both straps are an equal length to ensure that the weight of your backpack is evenly distributed. Once your backpack is correctly adjusted and customized, you can start to fill it up with whatever you need to carry.  Be careful when packing your bag to prevent fragile items from being broken.  Take some time to see how your items will best fit in your bag before putting it on to wear it.  Fragile items should go on top of more durable ones. Some items may have an usual shape or sharp corners.  Try to position these so that they don't poke you in the back. Make sure any containers storing liquids are secure before adding them to your bag. Don't carry more than 10%-15% of your body weight in your backpack to avoid injury. Now that your bag is full and adjusted, it's ready to wear.  Most backpacks will have two shoulder straps that will both need to be used.  Put an arm through each of the shoulder straps to make sure the weight is properly held by your backpack.  Take note of how comfortable the bag feels with items in it and make adjustments if needed.  Do not wear your backpack with only one shoulder strap. Each arm should go through a shoulder strap. Backpacks should not drop below the waist level. Don't wear your backpack slung low on your back.  You may need to adjust how you packed your items to evenly distribute the weight. Some backpacks will have an additional waist strap that can add more stability when worn. After you have found a great backpack, you can start to personalize it.  Personalizing your backpack can help keep it identifiable and allow you to express yourself at the same time.  Consider adding some contact information or other personal stylistic elements like patches, drawings, or tags to make your backpack feel like your own.  Writing your name and phone number on your bag can help it get back to you if lost. Customizing your bag can help you identify it easily if it's near similar bags.
Summary:
Adjust your backpack. Fill up your backpack. Wear your backpack. Personalize your backpack.
