An encyclopedia is a comprehensive reference work that provides information on a wide range of subjects, usually arranged in alphabetical order. It is a type of reference book that is intended to provide general knowledge about a subject, rather than in-depth, specialized information. Encyclopedias can be general, covering a wide range of subjects, or specialized, covering a particular field or area of study. They may include articles, definitions, illustrations, maps, and other types of information, and they are often written by experts in the field. Encyclopedias can be published in print or digital format, and they are used as a resource for research, learning, and general knowledge.

Electronic information resourcesالیکٹرانک معلومات کے وسائل

Electronic information resources are digital materials that are used for research or other purposes. They can include electronic books (e-books), electronic journals (e-journals), databases, websites, and other types of digital content. Electronic information resources are typically accessed via a computer or other electronic device with an internet connection. They can be accessed remotely, from anywhere with an internet connection, and can often be accessed through a library or other subscription service. Electronic information resources have several advantages over traditional print materials, including the ability to search for specific words or phrases, the ability to access materials from anywhere with an internet connection, and the ability to access older materials that may not be available in print.

Current periodicals

Current periodicals are magazines, newspapers, and other types of publications that are published on a regular basis, such as weekly, monthly, or quarterly. Current periodicals are often referred to as “serial publications” because they are published in a series of issues over time.

Current periodicals can cover a wide range of topics, including news, politics, science, business, entertainment, and more. They are an important source of information and are often used for research and other purposes. Many libraries and other institutions subscribe to current periodicals and make them available to patrons in print or electronic form.

Current periodicals differ from “back issues,” which are older issues of a periodical that are no longer being published. Back issues may be available for purchase or through library collections, but they are not considered current.

Copyright is a legal concept that gives the creators of original works, such as literature, music, and art, the exclusive right to control the reproduction and distribution of their work. Copyright law is intended to protect the intellectual property of creators and to encourage the creation of new works.

In most countries, copyright protection is automatic as soon as a work is created and fixed in a tangible form, such as being written down or recorded. The creator of the work does not need to register the work or include a copyright notice in order for it to be protected by copyright. However, registering a work and including a copyright notice can make it easier to enforce the creator’s rights if the work is infringed upon.

Copyright law varies from country to country, and the specific rights that are granted to creators may differ. In general, copyright law allows creators to control how their work is used and to receive payment for the use of their work. It also sets limits on the use of copyrighted material by others, such as the fair use doctrine, which allows for the limited use of copyrighted material without the permission of the copyright holder for purposes such as criticism, news reporting, teaching, scholarship, or research.
