Book /book/book 5 1,874,222

A book is a written work or a collection of written works in book form. "Book" represents the abstract notion of a particular book, rather than a particular edition. It is on this level that articles or discussion about a book should generally occur (e.g., the article about Mary Shelley's "Frankenstein" is on the book topic, rather than on one or more of the hundreds of editions it has gone through). For more information, please see the Freebase wiki page on book.

Book Edition /book/book_edition 25 1,102,603

A Book Edition represents a specific publication of a book. Print, audio, and electronic versions of books can all be represented as book editions.The title of a book edition should be the title of that particular edition, which may vary from other editions of the same book.  Mary Shelley's novel "Frankenstein," for example, has been published both as "Frankenstein" and "Frankenstein, or A Modern Prometheus."Please see Entering Data for a Book for more information.

This type is for series of book editions. That is to say, series where the items in the series are particular editions of books -- these will generally all have the same publisher, and may have a uniform binding or other unifying features such as all having the same illustrator or series editor. For series of books (i.e., series where you can say that any edition is part of the series), use the type Literary Series.

Short Non-fiction /book/short_non_fiction 1 1,981

This type should be used for any type of written short non-fiction that does not have a separate type. (Other types currently include review and interview.)  "Short" in this context means, essentially, anything less than book length; book-length non-fiction would ordinarily be typed as a book. This somewhat generic type both prevents a proliferation of similar types, and also reflects the fact that the difference between different modes of writing (say, between an article and an essay) can be hightly subjective, and may not always be important. The "mode of writing" property can be used to indicate the type of non-fiction it is (such as essay, introduction, etc.)  See Entering Reviews, Interviews, and Other Works of Short Non-fiction for more information.

Short Non-fiction Variety /book/short_non_fiction_variety 1 7

This is an enumerated list of possible varieties of written short non-fiction works, such as essay, article, introduction, etc., and functions primarily as a list to be used by the "short non-fiction" type. Please be conservative about adding new topics to this type. Topics such as "review" or "interview", which are indeed (usually) short works of non-fiction have their own types. (In general, if a variety of non-fiction needs properties beyond author, subject, and place of publication, it should have its own type.)

Short Story /book/short_story 2 4,449

The "short story" type is for works of prose fiction that are shorter than a novel in length. Since there is no universal agreement on what the minimum length for a novel is, there is necessarily a grey area here.

Technical report /book/technical_report 5 66

A technical report is a document that describes the process, progress, and or results of technical or scientific research or the state of a technical or scientific research problem. It might also includes recommendations and conclusion of the research.
