This example manuscript is intended to serve as a tutorial and template for authors to use when writing their own AAS Journal articles. The manuscript includes a history of   and documents the new features in the previous version, 6.0, as well as the new features in version 6.1. This manuscript includes many figure and table examples to illustrate these new features. Information on features not explicitly mentioned in the article can be viewed in the manuscript comments or more extensive online documentation. Authors are welcome replace the text, tables, figures, and bibliography with their own and submit the resulting manuscript to the AAS Journals peer review system. The first lesson in the tutorial is to remind authors that the AAS Journals, the Astrophysical Journal (ApJ), the Astrophysical Journal Letters (ApJL), and Astronomical Journal (AJ), all have a 250 word limit for the abstract. If you exceed this length the Editorial office will ask you to shorten it.

The arXiv is the most popular preprint repository in the world. Since its inception in 1991, the arXiv has allowed researchers to freely share publication-ready articles prior to formal peer review. The growth and the popularity of the arXiv emerged as a result of new technologies that made document creation and dissemination easy, and cultural practices that incentivized collaboration and data sharing. The arXiv represents a unique place in the history of research communication and the Web itself, however it has arguably changed very little since its creation.  Here we look at the strengths and weaknesses of arXiv in an effort to identify what possible improvements can be made based on new technologies not previously available. Based on this, we argue that a modern arXiv might in fact not look at all like the arXiv of today.

Research ArticlesResearch Articles report on original studies with broad impact across the fields of basic, translational, clinical, and epidemiologic cancer research as well as cancer prevention research. These articles should be of exceptional significance to a diverse audience of cancer researchers and scientists.

Research ArticlesOriginal studies offering broad impact across the fields of basic, preclinical, clinical, prevention, and epidemiologic cancer research. The reports should be well-documented, novel, and significant to the field as a whole. The Editor-in-Chief and members of the senior editorial board reserve the right to edit title, abstract, and précis for articles that are accepted to improve their clarity, brevity, and quality.

Mathematical Oncology Research ArticlesPublished in the Integrated Systems and Technologies section of the journal, Mathematical Oncology articles include mathematical approaches to problems in cancer research. These articles will contain new testable hypotheses, integration of theory and experimental data, facilitation of wide-ranging investigations, and basic laws of biology. The format and length restrictions for this category of publication are as follows:

Meeting ReportsBrief reports of symposia and conferences in cancer research. Reports must be submitted within 2 months of the meeting date in order to maintain their timeliness. Only those Meeting Reports dealing with topics of interest to the readership that contain novel information and insights from the meeting will be accepted for publication. A Meeting Report should offer a thoughtful, critical commentary that shows an appreciation of the connections among various presentations and reveals the consensus, if any, that emerged on matters of importance at the meeting. Before submitting a Meeting Report for consideration, potential authors must send a letter to the attention of Dr. Mariano Barbacid, Deputy Editor for Meeting Reports, to inquire whether the suggested meeting satisfies criteria for consideration. Letters of inquiry should be sent to the Publications Office (Fax: (215) 440-9354; E-mail: [email protected]). Length restrictions for this category of publication are as follows:100 word abstract2,500 words of textFigures and/or tables are not permitted without prior approval from the EditorsReferences, if necessary, must be kept to a minimumA statement of the purpose of the meeting, an integrated summary of the findings presented, and recommendations for future researchThe names and affiliations of key speakers should be given in an appendix that is submitted as supplemental information, not as part of the manuscript textAbstractThe abstract must be concise, yet should accurately outline the content of the manuscript (see the Categories of Articles page of each journal for abstract length requirements for each type of article). Because these abstracts are used by secondary services (e.g., MEDLINE, Chemical Abstracts, Web of Science, Scopus), they should recapitulate in abbreviated form the purpose of the study and the experimental technique, results, and data interpretations. Data such as the number of test subjects and controls, strains of animals or viruses, drug dosages and routes of administration, tumor yields and latent periods, length of observation period, and magnitude of activity should be included. Vague, general statements such as "The significance of the results is discussed" or "Some physical properties were studied" should be avoided. Important terms relevant to the content of the manuscript should be incorporated into the abstract to assist indexers and searchers. Abbreviations should be kept to an absolute minimum; however, if they are needed, they must be explained at first mention within the abstract so that it can be understood as an independent unit from the remainder of the manuscript. Do not cite references in the abstract.IntroductionThe introduction should provide a brief overview of the background and rationale for the study. It is not necessary to cite all of the background literature in the introduction. Brief reference to the most pertinent articles generally suffices to acquaint the reader with the findings of others in the field and with the problem or question that the investigation addresses. Sample citation \cite{Andor_2017}.Materials and MethodsExplanation of the experimental methods should be adequate for repetition by qualified investigators. Procedures that have been described in previous publications should not be described in detail but merely cited with appropriate references along with any modifications of the procedure. Only new and substantial modifications of previously published procedures need complete exposition. The sources of special chemicals or preparations used should be provided. Any commercial products that are mentioned should include the name of the manufacturer and catalog numbers.ResultsInclude a concise summary of the data presented in all display items (figures and tables). Excessive elaboration of data shown in display items should be avoided.DiscussionThe data should be interpreted concisely without repeating material already presented in the Results section. Speculation is permissible, but it must be well founded, and discussion of the wider implications of the findings is encouraged.AcknowledgmentsInclude the names of others contributing to the work who are not identified as authors.

Letters to the EditorIn the spirit of open scientific dialogue, the Editors invite the submission of correspondence that presents considered opinions in response to articles published in the journal. Letters to the Editor will be peer reviewed and, if found to meet the requisite publication criteria (scholarly commentary on a subject of importance and interest to the broad readership), the Letter may be sent to the author(s) of the originally published article and possibly to other interested parties for a response to be published in the same issue of the journal as the Letter. Please note that the journal will not consider Letters to the Editor regarding Cancer Research articles that were published more than 3 months prior. Correspondence concerning articles that have not been published in Cancer Research will not be considered. The length restrictions for this category of publication are as follows:400 words of text5 references, the first of which must be the citation for the original article under discussionLetters may contain figures or tables only if they show data that refute the conclusions of the originating article. Figures or tables showing unpublished data in support of the conclusions of the originating article will not be consideredInclude a title: "Running title of the original article" — LetterAbstractThe abstract must be concise, yet should accurately outline the content of the manuscript (see the Categories of Articles page of each journal for abstract length requirements for each type of article).
