Zotero Item Types and Fields

This page provides general descriptions of Zotero item types and fields. It can be helpful when entering item data into Zotero manually. The page also provides guidance on ways to store information for unusual item types.

Item Types

Item types in Zotero should be regarded as flexible, broad categories. Item types are generally determined based on how items should be cited. See descriptions of Zotero’s item types below. If you are citing an unusual item type that does not perfectly fit one of the supported categories, choose an item type that is reasonably close with an adequate selection of fields (e.g., Book, Report, or Manuscript can be made to fit most unusual item types well).

You can store more specific information about the type of item (e.g., a novel versus a biography book) in the Type, Format, or Extra fields or using tags.

Item Type Description
Artwork A piece of artwork (e.g., an oil painting, photograph, or sculpture). Also use this item type for other types of images or visual items (e.g., scientific figures).
Audio Recording Any form of audio recording, including music, spoken word, sound effects, archival recordings, or audio-based scientific figures.
Bill A proposed piece of legislation.
Blog Post An article or entry posted to a personal blog website. For online articles published as part of a larger online publication (e.g., NYT Blogs), using Magazine Article or Newspaper Article generally yields better results.
Book A book or similar published item. For government documents, technical reports, manuals, etc., use Report instead. This item type can also be adapted to fit many types of unusual items.
Book Section A section of a book. Usually chapters, but also forewords, prefaces, introductions, appendices, afterwords, comments, etc.
Case A legal case, either published or unpublished.
Computer Program A piece of software or other computer program.
Conference Paper A paper presented at a conference and subsequently published in a formal conference proceedings publication (e.g., as a book, report, or issue of a journal). For conference papers that have not been published in a proceedings, use Presentation.
Dictionary Entry An entry published as part of a dictionary.
Document A generic document item. This item type has a poor selection of fields and poor support in citation styles, so it should generally be avoided.
Email A message sent via email. This type could also be used for other forms of personal communication.
Encyclopedia Article An article or chapter published as part of an encyclopedia.
Film A film or motion picture. Generally, use this type for artistically-oriented films (including fictional, non-fictional, and documentary films). For other types of video items, use Video Recording.
Forum Post A post on an online discussion forum. Also use this type for items such as Facebook posts or tweets.
Hearing A formal hearing or meeting report by a legislative body.
Instant Message A message sent via an instant message or chat service. This type could also be used for other forms of personal communication.
Interview An interview with a person, including recordings, transcripts, or other records of the interview.
Journal Article An article published in a scholarly journal (either print or online).
Letter A letter sent between persons or organizations. This type could also be used for other forms of personal communication.
Magazine Article An article published in a non-scholarly, popular, or trade magazine (either print or online).
Manuscript An unpublished manuscript. Use this type for both historical documents and modern unpublished work (e.g., unpublished manuscripts, manuscripts submitted for publication, working papers that are not widely available). Can also be used for other forms of historical or archival documents. This item type can also be adapted to fit many types of unusual items.
Map A map. Also use this type for geographic models.
Newspaper Article An article published in a newspaper (either print or online).
Patent A patent awarded for an invention.
Podcast A podcast (an episode of an audio or video program distributed online, often via subscription).
Presentation A presentation made as part of a conference, meeting, symposium, lecture, etc. This item type refers to the presentation itself, not a written version published as part of a conference proceedings (use Conference Paper for such published versions).
Radio Broadcast An audio broadcast, such as a radio news show, an episode of a radio entertainment series, or similar. Includes broadcasts from online radio stations and audio broadcasts archived online (cf. Podcast).
Report A report published by an organization, institution, government department, or similar entity. Also used for working papers and preprints distributed through institutional repositories or preprint servers. This item type can also be adapted to fit many types of unusual items.
Statute A law or other piece of enacted legislation.
Thesis A thesis submitted as part of a student applying for a degree (either published or unpublished).
TV Broadcast An episode of a television series.
Video Recording A video recording. Use this type for general video items that do not fit into one of the more specific video item types (e.g., Film, TV Broadcast), such as YouTube videos or video-based scientific figures.
Webpage An online page of a website. When possible, use one of the more specific item types above (e.g., Magazine Article, Blog Post, Report).
Attachment A standalone attachment file (e.g., a PDF, JPEG, DOCX, PPTX, XLSX, or ODT file). Standalone attachment files have limited functionality in Zotero (e.g., they cannot be properly searched or cited). Always attach files to proper Zotero items.
Note A standalone note. Notes can be used for organizing and annotating in Zotero. If you cite a standalone note, Zotero will use the first 120 characters as the item title (and will treat the note as an author-less and date-less item). Citing notes is not a reliable way to add standalone commentary to a bibliography or reference list.

For additional legal and historical item types, see Legal Citations.

Item Fields

Fields included for various item types in Zotero are described below. Fields are organized into categories based on the kinds of items they are most typically associated with. Some fields (e.g., Volume, Series) may also be present for other types of items. Specific meanings of fields for particular item types are noted where necessary.

Fields marked with an asterisk (*) cannot be used in citations

General Fields

The following fields exist across multiple item types and have the same purpose for all (or nearly all) types.

Field Description
Item Type The broad type of item. Item types are generally determined based on how items should be cited. See descriptions of Zotero’s item types above. You can store more specific information about the type of item (e.g., a novel versus a biography book) in the Type, Format, or Extra fields or using tags.
Creators The individuals or entities creating or associated with a work. An item can have multiple creators of numerous different kinds. See the list of creator types below.
Title The principal title of an item. Should be entered in sentence case.
Abstract Short description of the work
Date Date of publication. Use “Accessed” for the date an electronic resource was accessed.
Short TitleShort form of the title, often without the subtitle. Used mostly in footnote styles for subsequent citations
Language The language of publication for an item. We recommend storing these as two letter ISO language codes followed by two letter ISO country codes (e.g., en-US for American English, or de-DE for German).
The Language field is used to determine whether English Title Casing rules should be applied when formatting item titles. If the stored item data is in English (e.g., for translated titles), enter en-US or en-UK, even if the item content is in another language.

Fields for Books and Periodicals

Field Description
Publication The title of the periodical (journal, magazine, newspaper, etc.) containing the cited item
Book Title
Dictionary Title
Encyclopedia Title
The title of the book, encyclopedia, or dictionary that a chapter, entry, or other book section is published in.
Volume The volume of a (typically multi-volume) publication an article or chapter is published in. For numeric volumes, enter only a number. If the volume should be cited with a volume title, include the title in this field (e.g,. “2: Organizational Psychology”).

Series Number The number of an item in a series.
Series Title Title of a series of articles within one issue of a journal (e.g., a special section or “From the Cover”). “Section Title” would likely be a more appropriate label. See here for an explanation. For citation purposes, this field is currently equivalent to “Series” and is erroneously used instead of series in some item types (e.g., Audio Recording, Map).
# of Volumes The number of volumes in a collective work.
# of Pages The number of pages in a book.
Section Section of a newspaper.
Place The place of publication for an item.

For citations to films, recordings, and broadcasts, Zotero currently has limited to support for labeling producers, scriptwriters, and some other Creator roles.

To label directors, leave the main Zotero field blank (or enter the names as Contributor) and enter the director names using Director in Extra. See Citing Fields from Extra below.

All Creator roles (Director, Producer, Scriptwriter, etc.) can also be labelled by entering the names using the default author role for the item (Performer for Audio Recording, Podcaster for Podcast, and Director for Film, Radio Broadcast, TV Broadcast, and Video Recording) and adding the appropriate labels in parentheses after the authors' first names or last names as appropriate for your citation style—e.g., MacNaughton || Ian (Producer) for APA style. Note that the labels will be rendered verbatim in citations; enter abbreviated terms (e.g., “Prod.”) here as needed.
