How to Create a Home Library
"I cannot live without books," declared U. S. President Thomas Jefferson to his friend John Adams. Indeed, Jefferson was an obsessive book collector from a young age, amassing (收集) three separate home libraries in his lifetime. Jefferson's library was considered the finest in the country, and his collection doubled the holdings of the Library of Congress. Still, Jefferson didn't let the shelves at Monticello sit empty. By the time he died 11 years later, he had more than 2 000 volumes in his library.
Jefferson's library might fit your conception of an old-fashioned home library with leather-bound books, wood paneling and uncomfortable furniture. But home libraries can be a dynamic expression of the owner's personality. Creating a home library is a fun way to display your interests while establishing a special space for reading.
Home Library Organization
When you started using the public library, you probably learned about Melvil Dewey and his system for ordering libraries. The Dewey Decimal Classification System has ten broad categories for organizing books, including philosophy, religion and the arts. Each category is assigned a number, so for example, when you want a book on modern art, you head to the 700 block. Larger libraries, such as those at universities, tend to use the Library of Congress Classification System because it offers a more specific array of subjects for categorization, adding subjects such as medicine and law for a total of 21 categories.
Your home library may or may not be as large as your local public library, but a good system of organization will still help you find the book you want quickly. You could take a page from Dewey and the Library of Congress and sort books by subject matter. Sections for subjects such as history, technology or fiction might make their retrieval easier. This system also would allow you to highlight a particular passion, such as an extensive collection of World War II history.
Here are some other ways to organize a collection.
Alphabetizing by author works well for fiction but not necessarily for nonfiction books of various subjects.
Judging a book by its cover is usually frowned upon, but sorting by color can be aesthetically pleasing to some. Those generally forgetful about the colors of their books might disagree.
After a painful breakup, the main character in Nick Hornby's book "High Fidelity" organizes his record collection autobiographically in the order he acquired them. A chronological organization might include shelves that track the progress of your life, from beloved childhood reading and college text-books to parenting books.
To some readers, there are two ways to look at books: read and unread. Prioritizing (区分优先次序) when you might need the book will allow you to keep unread books at the forefront of your collection, as well as books you reach for frequently, such as reference books or favorite novels.
Library Furniture
While it might be difficult for a book lover to spend money on something other than books, at some point ,you will need some bookshelves. Built-in, bookshelves can provide floor-to-ceiling storage and space savings. They can be tucked under staircases or other out-of-the-way spaces; however, they're not a good choice for renters, and they can represent a big investment in terms of price and installation. Freest
