DIGITAL  LIBRARY
   A digital library is a special library with a focused collection of digital objects that can include text, visual material, audio material, video material, stored as electronic media formats (as opposed to print, microform, or other media), along with means for organizing, storing, and retrieving the files and media contained in the library collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals, organizations, or affiliated with established physical library buildings or institutions, or with academic institutions.The digital content may be stored locally, or accessed remotely via computer networks. An electronic library is a type of information retrieval system.
History
       Early projects centered on the creation of an electronic card catalogue known as Online Public Access Catalog (OPAC). By the 1980s, the success of these endeavors resulted in OPAC replacing the traditional card catalog in many academic, public and special libraries. This permitted libraries to undertake additional rewarding co-operative efforts to support resource sharing and expand access to library materials beyond an individual library.
       An early example of a digital library is the Education Resources Information Center (ERIC) which was "born digital" in 1966.
Terminology
        The term digital libraries was first popularized by the NSF/DARPA/NASA Digital Libraries Initiative in 1994. These draw heavily on Vannevar Bush's essay As We May Think (1945), which set out a vision not in terms of technology, but user experience. The term virtual library was initially used interchangeably with digital library, but is now primarily used for libraries that are virtual in other senses (such as libraries which aggregate distributed content). In the early days of digital libraries, there was discussion of the similarities and differences among the terms digital, virtual, and electronic.
          In the context of the DELOS, a Network of Excellence on Digital Libraries, and DL.org, a Coordination Action on Digital Library Interoperability, Best Practices and Modelling Foundations, Digital Library researchers and practitioners and software developer produced a Digital Library Reference Model which defines a digital library as: "A potentially virtual organization, that comprehensively collects, manages and preserves for the long depth of time rich digital content, and offers to its targeted user communities specialized functionality on that content, of defined quality and according to comprehensive codified policies."
           A distinction is often made between content that was created in a digital format, known as born-digital, and information that has been converted from a physical medium, e.g. paper, through digitization. It should also be noted that not all electronic content is in digital data format. The term hybrid library is sometimes used for libraries that have both physical collections and electronic collections. For example, American Memory is a digital library within the Library of Congress.
          Some important digital libraries also serve as long term archives, such as arXiv and the Internet Archive. Others, such as the Digital Public Library of America, seek to make digital information from various institutions widely accessible online.
ERIC SOFTWARE

      The given name Eric, Erik, or Erick is derived from the Old Norse name Eiríkr (or Æinrikr in Eastern Scandinavia due to monophthongization). The first element, ei- is derived either from the older Proto-Norse aina(z) meaning "one" or "alone"or from Proto-Norse aiwa(z) meaning "ever" or "eternal". The second element -ríkr derives either from rík(a)z meaning "ruler" or "prince" (cf. Gothic reiks) or from an even older Proto-Germanic ríkiaz which meant "powerful" and "rich". The name is thus usually taken to mean "one ruler", "autocrat", "eternal ruler" or "ever powerful", "warrior", and "government".
     The most common spelling in Scandinavia is Erik. In Norway, another form of the name (which has kept the Old Norse diphthong) Eirik is also commonly used.In Finland, the form Erkki is also used. The modern Icelandic version is Eiríkur, while the modern Faroese version is Eirikur. Éric [eʁik] is used in French, and in Germany Eric, Erik and Erich are used.
       Although the name was in use in Anglo-Saxon England, its use was reinforced by Scandinavian settlers arriving before the Norman Invasion. It was an uncommon name in England until the Middle Ages, when it gained popularity, and finally became a common name in the 19th century. This was partly because of the publishing of the novel Eric, or, Little by Little by Frederick William Farrar in 1858.
In NorwaySweden and Finland, the name day for Erik and Eirik is 18 May, commemorating the death of Saint Eric of Sweden.
The feminine derivative is Erica or Erika.

GOOGLE BOOKS
             Google Books (previously known as Google Book Search and Google Print) is a service from Google Inc. that searches the full text of books and magazines that Google has scanned, converted to text using optical character recognition (OCR), and stored in its digital database. Books are provided either by publishers and authors, through the Google Books Partner Program, or by Google's library partners, through the Library Project. Additionally, Google has partnered with a number of magazine publishers to digitize their archives.
        The Publisher Program was first known as 'Google Print' when it was introduced at the Frankfurt Book Fair in October 2004. The Google Books Library Project, which scans works in the collections of library partners and adds them to the digital inventory, was announced in December 2004.
            The Google Books initiative has been hailed for its potential to offer unprecedented access to what may become the largest online body of human knowledge and promoting the democratization of knowledge.But it has also been criticized for potential copyright violations, and lack of editing to correct the many errors introduced into the scanned texts by the OCR process.
        As of October 2015, the number of scanned book titles was over 25 million, but the scanning process has slowed down in American academic libraries. Google estimated in 2010 that there were about 130 million distinct titles in the world, and stated that it intended to scan all of them.

ENCYCLOPEDIA
             An encyclopedia or encyclopaedia (also spelled encyclopædia, see spelling differences) is a type of reference work or compendium holding a comprehensive summary of information from either all branches of knowledge or a particular branch of knowledge. Encyclopedias are divided into articles or entries, which are usually accessed alphabetically by article name.Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, unlike dictionary entries which focus on linguistic information about words, encyclopedia articles focus on factual information concerning the subject for which the article is named.
Encyclopedias have existed for around 2,000 years; the oldest still in existence, Naturalis Historia, was written starting in ca. AD 77 by Pliny the Elder and was not fully revised at the time of his death in AD 79. The modern encyclopedia evolved out of dictionaries around the 17th century. Historically, some encyclopedias were contained in one volume, whereas others, such as the Encyclopædia Britannica, the Enciclopedia Italiana (62 volumes, 56,000 pages) or the world's largest, Enciclopedia universal ilustrada europeo-americana (118 volumes, 105,000 pages), became huge multi-volume works. Some modern encyclopedias, such as Wikipedia, are electronic and often freely available.

DIGITAL DICTIONARY
                  A dictionary is a collection of words in one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologiesphoneticspronunciations, translation, etc.or a book of words in one language with their equivalents in another, sometimes known as a lexicon .It is a lexicographical product which shows inter-relationships among the data.
                      A broad distinction is made between general and specialized dictionaries. Specialized dictionaries include words in specialist fields, rather than a complete range of words in the language. Lexical items that describe concepts in specific fields are usually called terms instead of words, although there is no consensus whether lexicology and terminology are two different fields of study. In theory, general dictionaries are supposed to be semasiological, mapping word to definition, while specialized dictionaries are supposed to be onomasiological, first identifying concepts and then establishing the terms used to designate them. In practice, the two approaches are used for both types.There are other types of dictionaries that do not fit neatly into the above distinction, for instance bilingual (translation) dictionaries, dictionaries of synonyms , and rhyming dictionaries. The word dictionary (unqualified) is usually understood to refer to a general purpose monolingual dictionary.
            There is also a contrast between prescriptive or descriptive dictionaries; the former reflect what is seen as correct use of the language while the latter reflect recorded actual use. Stylistic indications (e.g. "informal" or "vulgar") in many modern dictionaries are also considered by some to be less than objectively descriptive.

Advantages

         The advantages of digital libraries as a means of easily and rapidly accessing books, archives and images of various types are now widely recognized by commercial interests and public bodies alike.
           Traditional libraries are limited by storage space; digital libraries have the potential to store much more information, simply because digital information requires very little physical space to contain it. As such, the cost of maintaining a digital library can be much lower than that of a traditional library. A physical library must spend large sums of money paying for staff, book maintenance, rent, and additional books. Digital libraries may reduce or, in some instances, do away with these fees. Both types of library require cataloging input to allow users to locate and retrieve material. Digital libraries may be more willing to adopt innovations in technology providing users with improvements in electronic and audio book technology as well as presenting new forms of communication such as wikis and blogs; conventional libraries may consider that providing online access to their OP AC catalog is sufficient. An important advantage to digital conversion is increased accessibility to users. They also increase availability to individuals who may not be traditional patrons of a library, due to geographic location or organizational affiliation.
·         No physical boundary. The user of a digital library need not to go to the library physically; people from all over the world can gain access to the same information, as long as an Internet connection is available.
·         Round the clock availability A major advantage of digital libraries is that people can gain access 24/7 to the information.
·         Multiple access. The same resources can be used simultaneously by a number of institutions and patrons. This may not be the case for copyrighted material: a library may have a license for "lending out" only one copy at a time; this is achieved with a system of digital rights management where a resource can become inaccessible after expiration of the lending period or after the lender chooses to make it inaccessible (equivalent to returning the resource).
·         Information retrieval. The user is able to use any search term (word, phrase, title, name, subject) to search the entire collection. Digital libraries can provide very user-friendly interfaces, giving click able access to its resources.
·         Preservation and conservation. Digitization is not a long-term preservation solution for physical collections, but does succeed in providing access copies for materials that would otherwise fall to degradation from repeated use. Digitized collections and born-digital objects pose many preservation and conservation concerns that analog materials do not. Please see the following "Problems" section of this page for examples.
·         Space. Whereas traditional libraries are limited by storage space, digital libraries have the potential to store much more information, simply because digital information requires very little physical space to contain them and media storage technologies are more affordable than ever before.
·         Added value. Certain characteristics of objects, primarily the quality of images, may be improved. Digitization can enhance legibility and remove visible flaws such as stains and discoloration.
·         Easily accessible.
Disadvantages
       Digital libraries, or at least their digital collections, unfortunately also have brought their own problems and challenges in areas such as:There are many large scale digitisation projects that perpetuate this problem.
·         User authentication for access to collections
·         Copyright
·         Digital preservation (see above)
·         Equity of access (see digital divide)
·         Interface design
·         Interoperability between systems and software
·         Information organization
·         Inefficient or non existent taxomomy practices (especially with historical material)
·         Training and development
·         Quality of Metadata
