# விக்கிப்பீடியா:குறிப்பிடத்தக்கமை (நூல்கள்)



## Coverage notes
Though the concept of a "நூல் (எழுத்துப் படைப்பு)" is widely defined, this guideline does not provide specific notability criteria for the following types of publications: comic books; graphic novels (although it does apply to மங்கா); magazines; reference works such as dictionaries, thesauruses, encyclopedias, atlases and almanacs; music-specific publications such as instruction and notation books and librettos; instruction manuals; and exam prep books. Specific guidelines may be developed. Until then, this guideline may be instructive by analogy.  

The criteria set forth below apply to books in electronic form (or மின்னூல்). An e-book that does not meet the criteria of this guideline is nevertheless notable if it meets the criteria of the notability guideline for web-specific content. An e-book that meets the criteria of this guideline does not need to meet the criteria of that guideline in order to be notable. A book included in குட்டன்பேர்க் திட்டம் or an analogous project does not need to meet the threshold standards.  

## Criteria

A book is notable if it verifiably meets, through , at least **one** of the following criteria:  
1. The book has been the subject Exceptions do exist, such as Robert Gunther's *Early Science in Oxford* and எட்கர் ஆலன் போ's *Tamerlane*, but both of these books would be considered notable by virtue (for instance) of criterion 1.

Many vanity press books are assigned ISBN numbers, may be listed in a national library, may be found through a கூகுள் புத்தகங்கள் search, and may be sold at large online book retailers of which is evidence of notability.  

#### Books by Wikipedians
That a Wikipedia article on a book has been created by the author of that book or by any other interested party such as an editor or member of the editorial staff of that book has no bearing on whether or not that book is notable, though it does mean the person creating or editing that article has a conflict of interest and is expected to abide by the relevant Wikipedia guideline with regard to conflict-of-interest editing and the by the Wikimedia Foundation's terms of use. See விக்கிப்பீடியா:நலமுரண் and விக்கிப்பீடியா:தன்வரலாறு for more information. Failure to properly disclose a COI may result in the blocking of a user's account, though it is not necessarily a basis for nominating the associated article for deletion.  

#### Online bookstores

A book's listing at online bookstores Barnes & Noble.com and அமேசான்.காம், is not an indication of notability because the websites include large numbers of vanity press publications. A listing at any other online bookstore that includes large numbers of vanity press publications should be treated in the same way.  

#### Not-yet-published books

Articles about books that are not yet published are accepted only if they are not excluded by the Wikipedia is not a crystal ball policy, and only under criteria other than those provided by this guideline, typically because the anticipation of the book is notable in its own . In such cases there should be independent sources which provide strong evidence that the book will be published, and which include the title of the book and an approximate date of publication.  

#### Non-contemporary books

The vast majority of books whose Wikipedia articles are nominated for deletion, and whose notability could reasonably be called into question, are contemporary. Nevertheless, the notability of books written or published earlier may occasionally be disputed and the criteria specified above, intended primarily for contemporary books, may be unsuitable because they would be too restrictive and would exclude articles on books that are worthy of notice.  

Common sense should prevail. In such cases, possible bases for a finding of notability include, in particular, how widely the book has been cited or written about, the number of editions of the book, whether it has been reprinted, the fame that the book enjoys or enjoyed in the past, its place in the இலக்கிய வரலாறு, its value as a historical source and its age.  

#### Academic and technical books

Academic and technical books serve a very different function and come to be published through very different processes than do books intended for the general public. They are often highly specialized, have small printing runs, and may only be available in specialized libraries and bookstores. For these reasons, most of the standards for mainstream books are inapplicable to the academic field because they would be too restrictive and would exclude articles on books that are worthy of notice. Again, common sense should prevail. In such cases, possible bases for a finding of notability include, in particular, whether the book is published by an academic press, how widely the book is cited by other academic publications or in the media, the number of editions of the book, whether one or more translations of the book have been published, how influential the book is considered to be in its specialty area, or adjunct disciplines, and whether it is, or has been, taught, or required reading, in one or more reputable educational institutions.  

## Derivative articles

Articles on books should not be split and split again into ever more minutiae of detail treatment, with each split normally lowering the level of notability. While a book may be notable, it is not normally advisable to have a separate article on a character or thing from the book, and it is often the case that despite the book being manifestly notable, a derivative article from it is not. Exceptions do exist, especially in the case of very famous books. For example, சார்லஸ் டிக்கின்ஸ்' *A Christmas Carol* clearly warrants a 'subarticle' on its protagonist, Ebenezer Scrooge. When a book has been split too finely to support the notability of individual subtopics, merging content back into the book's article is appropriate.  

In some situations— for example, if a given book itself does not appear to be notable, but the author is notable— it may be more appropriate to feature material about the book in the author's article rather than creating a separate article for that book. It may sometimes be appropriate to merge an article on a book into an article that is a bibliography or list of books. This might, for example, facilitate the inclusion of material on anonymous works that, because those works are anonymous, cannot be merged into their authors' articles. If, in such a case, the book cannot be merged only because the notable author's article, or the bibliography or list of books, does not currently exist, consider writing the author's article, or the bibliography or list, yourself or request that it be written.
