Citation managers store, organize, and format citations for papers and bibliographies in a variety of output styles such as APA or MLA. Many citation managers include features such as allowing users to annotate a citation, attach a PDF to the citation, collaborate with others, or create in-text citations. The four most commonly used citation manager programs at the University of Delaware are:
RefWorks
The University of Delaware Library has a subscription to RefWorks. Users can create multiple accounts, which are easy to share among research groups and with class project teammates. Undergraduates will find this tool generally easy to use. A strong Write-N-Cite component is available for use when writing a paper. Graduate students will find the organizational options in RefWorks an aid in the research and writing process. Faculty may find the ease of sharing bibliographies with students an advantage of RefWorks.
EndNote online with the Web of Science
EndNote online is built into Web of Science and is especially easy to use with this database. EndNote is a rather sophisticated citation manager and offers a large number of citation formats and options. The capabilities of the purchased EndNote software that is loaded on one's computer differ from those of the web product provided by the Library. EndNote features comparison chart.
Zotero
Zotero is a free, easy to use, open source citation manager available on the web. Many users like Zotero because of its simple integration into the browser and its ability to add PDFs, images, audio and video files, and snapshops of web page with a single click.
Mendeley
Mendeley is also free on the web. The social networking capabilities are a major attraction of this citation management software.
If you'd like to use one or more of these tools, consider signing up for a workshop to learn all of the features.

The following supplemental example references are mention in the Publication Manual:
Archival document and collections are not presented in the APA Publication Manual, Seventh Edition. This content is available only on the APA Style website. This guidance has been expanded from the 6th edition.
Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.
The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

Read the full APA guidelines on citing ChatGPT
OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat
Author: The author of the model is OpenAI.
Date: The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.
Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.
The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.
Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.
Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat. For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).
The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not bibliographies.
In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.
There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.
Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the APA Publication Manual, Seventh Edition
The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.
Follow these guidelines for including DOIs and URLs in references:
Follow these guidelines to format DOIs and URLs:
https://doi.org/xxxxx
When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.
