Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Library shopping experience:

1. Compare - without doubt the biggest advantage that the Library offers shoppers today is the ability to compare thousands of Library at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Library? Wrong! If the Library is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Library then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Library? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Library and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Library wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Library then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Library site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Library, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Library, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.



, ColombiaA library is a collection of information, sources, resources, and services: it is organized for use and maintained by a public body, an institution, or a private individual. In the more traditional sense, a library is a collection of books.

This collection and services are used by people who choose not to — or cannot afford to — purchase an extensive collection themselves, who need material no individual can reasonably be expected to have, or who require professional assistance with their research.

However, with the collection of data storage device other than books for recording, many libraries are now also repositories and access points for maps, print rooms, or other documents and Work of arts on various storage media such as microform (microfilm/microfiche), audio tapes, Compact discs, Gramophone records, compact cassette, videotapes, and DVDs. Libraries may also provide public facilities to access CD-ROMs, subscription databases, and the Internet.

Thus, modern libraries are increasingly being redefined as places to get unrestricted access to information in many formats and from many sources. In addition to providing materials, they also provide the services of specialists, librarians, who are experts at finding and organizing information and at interpreting information needs.

More recently, libraries are understood as extending beyond the physical walls of a building, by including material accessible by electronic means, and by providing the assistance of librarians in navigating and analyzing tremendous amounts of knowledge with a variety of digital tools.

The term "library" has itself acquired a secondary meaning: "a collection of useful material for common use," and in this sense is used in fields such as computer science, mathematics and statistics, Library (electronics) and Library (biology).

History branch of the National Library of IranThe first libraries were only partly libraries, being composed for the most part of unpublished documents, which are usually viewed as archives, not libraries. Archaeological findings from the ancient city-states of Sumer have revealed temple rooms full of clay tablets in cuneiform script. These archives were made up almost completely of the records of commercial transactions or inventories, with only a few documents touching theological matters, historical records or legends. Things were much the same in the government and temple records on papyrus of Ancient Egypt.

The earliest discovered private archives were kept at Ugarit; besides correspondence and inventories, texts of myths may have been standardized practice-texts for teaching new scribes.

Private or personal libraries made up of non-fiction and fiction books (as opposed to the state or institutional records kept in archives) first appeared in classical Greece. The first ones appeared some time near the 5th century BC. The celebrated book collectors of Hellenistic Antiquity were listed in the late second century in Deipnosophistae:Epitome of Book I

All these libraries were Greek; the cultivated Hellenized diners in Deipnosophistae pass over the libraries of Rome in silence. At the Villa of the Papyri at Herculaneum, apparently the villa of Caesar's father-in-law, the Greek library has been partly preserved in volcanic ash; archaeologists speculate that a Latin library, kept separate from the Greek one, may await discovery at the site.

Libraries were filled with parchment scroll (parchment) as at Pergamum and on papyrus scrolls as at Alexandria: export of prepared writing materials was a staple of commerce. There were a few institutional or royal libraries like the Library of Alexandria which were open to an educated public, but on the whole collections were private. In those rare cases where it was possible for a scholar to consult library books there seems to have been no direct access to the stacks. In all recorded cases the books were kept in a relatively small room where the staff went to get them for the readers, who had to consult them in an adjoining hall or covered walkway.

Little is known about early China libraries, save what is written about the imperial library which began with the Qin Dynasty. One of the curators of the imperial library in the Han Dynasty is believed to have been the first to establish a library classification system and the first book notation system. At this time the library catalog was written on scrolls of fine silk and stored in silk bags. There is also evidence of those libraries at Nippur of about 1900 B.C. and those at Nineveh of about 700 B.C. as showing a library classification system.The American International Encyclopedia, J.J. Little & Ives, New York 1954, Volume IX at University of California, San Diego, with its unique architecture, is a San Diego, California landmark.In Iran many libraries were established by the Zoroastrian elite and the Persian Kings. Among the first ones was a royal library in Isfahan (city). One of the most important public libraries established around 667 AD in south-western Iran was the Library of Gundishapur. It was a part of a bigger scientific complex located at the Academy of Gundishapur.

In the West, the first public libraries were established under the Roman Empire as each succeeding emperor strove to open one or many which outshone that of his predecessor. Unlike the Greek libraries, readers had direct access to the scrolls, which were kept on shelves built into the walls of a large room. Reading or copying was normally done in the room itself. The surviving records give only a few instances of lending features. As a rule Roman public libraries were bilingual: they had a Latin room and a Greek room. Most of the large Roman baths were also cultural centers, built from the start with a library, with the usual two room arrangement for Greek and Latin texts.

In the sixth century, at the very close of the Classical period, the great libraries of the Mediterranean world remained those of Constantinople and Alexandria. Cassiodorus, minister to Theodoric, established a monastery at Vivarium in the heel of Italy with a library where he attempted to bring Greek learning to Latin readers and preserve texts both sacred and secular for future generations. As its unofficial librarian, Cassiodorus not only collected as many manuscripts as he could, he also wrote treatises aimed at instructing his monks in the proper uses of reading and methods for copying texts accurately. In the end, however, the library at Vivarium was dispersed and lost within a century.

Elsewhere in the Early Middle Ages, after the fall of the Western Roman Empire and before the rise of the large Western Christianity monastery libraries beginning at Montecassino, libraries were found in scattered places in the Christian Middle East. Upon the rise of Islam, libraries in newly Islamic lands knew a brief period of expansion in the Middle East, North Africa, Sicily and Spain. Like the Christian libraries, they mostly contained books which were made of paper, and took a codex or modern form instead of scrolls; they could be found in mosques, private homes, and universities. In Aleppo, for example the largest and probably the oldest mosque library, the Sufiya, located at the city's Grand Umayyad Mosque, contained a large book collection of which 10 000 volumes were reportedly bequeathed by the city's most famous ruler, Prince Sayf al-Dawla. Some mosques sponsored public library. Ibn al-Nadim's bibliography Fihrist demonstrates the devotion of medieval Muslim scholars to books and reliable sources; it contains a description of thousands of books circulating in the Islamic world circa 1000, including an entire section for books about the doctrines of other religions. Unfortunately, modern Islamic libraries for the most part do not hold these antique books; many were lost, Battle of Baghdad (1258), or removed to European libraries and museums during the colonial period.

By the 8th century first Iranians and then Arabs had imported the craft of paper making from China, with a mill already at work in Baghdad in 794. By the 9th century completely public libraries started to appear in many Islamic cities. They were called "halls of Science" or dar al-'ilm. They were each endowed by Islamic sects with the purpose of representing their tenets as well as promoting the dissemination of secular knowledge. The 9th century Abbasid Caliph al-Mutawakkil of Iraq, even ordered the construction of a ‘zawiyat qurra literally an enclosure for readers which was `lavishly furnished and equipped.' In Shiraz Adhud al-Daula (d. 983CE) set up a library, described by the medieval historian, al-Muqaddasi, as`a complex of buildings surrounded by gardens with lakes and waterways. The buildings were topped with domes, and comprised an upper and a lower story with a total, according to the chief official, of 360 rooms.... In each department, catalogues were placed on a shelf... the rooms were furnished with carpets...'. The libraries often employed translators and copyists in large numbers, in order to render into Arabic the bulk of the available Persian, Greek and Roman non-fiction and the classics of literature. This flowering of Islamic learning ceased after a few centuries as the Islamic world began to turn against experimentation and learning. After a few centuries many of these libraries were destroyed by Mongolian invasion. Others were victim of wars and religious strife in the Islamic world. However, a few examples of these medieval libraries, such as the libraries of Chinguetti in West Africa, remain intact and relatively unchanged even today. Another ancient library from this period which is still operational and expanding is the Central Library of Astan Quds Razavi in the Iranian city of Mashhad, which has been operating for more than six centuries.

The contents of these Islamic libraries were copied by Christian monks in Muslim/Christian border areas, particularly Spain and Sicily. From there they eventually made their way into other parts of Christian Europe. These copies joined works that had been preserved directly by Christian monks from Greek and Roman originals, as well as copies Western Christian monks made of Byzantine Empire works. The resulting conglomerate libraries are the basis of every modern library today.

Medieval library design reflected the fact that these manuscripts--created via the labor-intensive process of hand copying--were valuable possessions. Library architecture developed in response to the need for security. Librarians often chained books to lecterns, armaria (wooden chests), or bookshelf, in well-lit rooms. Despite this protectiveness, many libraries were willing to lend their books if provided with security deposits (usually money or a book of equal value). Monastic libraries lent and borrowed books from each other frequently and lending policy was often theologically grounded. For example, the Franciscan monasteries loaned books to each other without a security deposit since according to their vow of poverty only the entire order could own property. In 1212 the council of Paris condemned those monasteries that still forbade loaning books, reminding them that lending is "one of the chief works of mercy."

The earliest example in England of a library to be endowed for the benefit of users who were not members of an institution such as a cathedral or college was the Francis Trigge Chained Library in Grantham, Lincolnshire, established in 1598. The library still exists and can justifiably claim to be the forerunner of later public library systems.

The early libraries located in monastic cloisters and associated with scriptorium were collections of lecterns with books chained to them. Shelves built above and between back-to-back lecterns were the beginning of bookpresses. The chain was attached at the fore-edge of a book rather than to its spine. Book presses came to be arranged in carrel desk (perpendicular to the walls and therefore to the windows) in order to maximize lighting, with low bookcases in front of the windows. This stall system (fixed bookcases perpendicular to exterior walls pierced by closely spaced windows) was characteristic of England institutional libraries. In Continental Europe libraries, bookcases were arranged parallel to and against the walls. This wall system was first introduced on a large scale in Spain's El Escorial.

As books became more common, the need for chaining them lessened. But as the number of books in libraries increased, so did the need for compact storage and access with adequate lighting, giving birth to the stack system, which involved keeping a library's collection of books in a space separate from the reading room, an arrangement which arose in the 19th century. Book stacks quickly evolved into a fairly standard form in which the cast iron and steel frameworks supporting the bookshelves also supported the floors, which often were built of translucent blocks to permit the passage of light (but were not transparent, for reasons of modesty). With the introduction of Electric light, it had a huge impact on how the library lighting in libraries. Also, the use of glass floors was largely discontinued, though floors were still often composed of metal grating to allow air to circulate in multi-story stacks.Ultimately, even more space was needed, and a method of moving shelves on tracks (compact shelving) was introduced to cut down on otherwise wasted aisle space.

Types of libraries Libraries can be divided into categories by several methods:

Also, the governments of most major countries support national library. Three noteworthy examples are the U.S. Library of Congress, Canada's Library and Archives Canada, and the British Library. A typically broad sample of libraries in one state in the U.S. can be explored at Every Library In Illinois.

Organization Libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections may be browsed efficiently. Some libraries have additional galleries beyond the public ones, where reference materials are stored. These reference stacks may be open to selected members of the public. Others require patrons to submit a "stack request," which is a request for an assistant to retrieve the material from the closed stacks.

Larger libraries are often broken down into departments staffed by both paraprofessionals and professional librarians.

Library use Library patrons may not know how to use a library effectively. This can be due to lack of early exposure, shyness, or anxiety and fear of displaying ignorance. In United States public library, beginning in the 19th century these problems drove the emergence of the library instruction movement, which advocated library user education. One of the early leaders was John Cotton Dana. The basic form of library instruction is generally known as information literacy.

Libraries inform their users of what materials are available in their collections and how to access that information. Before the computer age, this was accomplished by the card library catalog — a cabinet containing many drawers filled with index cards that identified books and other materials. In a large library, the card catalog often filled a large room. The emergence of the Internet, however, has led to the adoption of electronic catalog databases (often referred to as "webcats" or as OPACs, for "online public access catalog"), which allow users to search the library's holdings from any location with Internet access. This style of catalog maintenance is compatible with new types of libraries, such as digital library and distributed library, as well as older libraries that have been retrofitted. Electronic catalog databases are disfavored by some who believe that the old card catalog system was both easier to navigate and allowed retention of information, by writing directly on the cards, that is lost in the electronic systems. This argument is analogous to the debate over paper books and e-books. While they have been accused of precipitously throwing out valuable information in card catalogs, most modern libraries have nonetheless made the movement to electronic catalog databases.

Finland has the highest number of registered book borrowers per capita in the world. Over half of Finland's population are registered borrowers.

Library management Basic tasks in library management include the planning of acquisitions (which materials the library should acquire, by purchase or otherwise), library classification of acquired materials, preservation of materials (especially rare and fragile archival materials such as manuscripts), the deaccessioning of materials, patron borrowing of materials, and developing and administering library computer systems. More long-term issues include the planning of the construction of new libraries or extensions to existing ones, and the development and implementation of outreach services and reading-enhancement services (such as adult literacy and children's programming).
