Author Guidelines

Free format submission

The American Journal of Hematology now offers free format submission for a simplified and streamlined submission process.

Before you submit, you will need:

  • Your manuscript: this can be a single file including text, figures, and tables. All required sections should be contained in your manuscript, including abstract, introduction, methods, results, and conclusions. For all article types a figure legend must be provided for each figure and must define all abbreviations used therein. Figure legends should be placed at the end of the manuscript text file. Do not include the labelling or legend directly in the figure file. References may be submitted in any style or format, as long as it is consistent throughout the manuscript. If the manuscript, figures or tables are difficult for you to read, they will also be difficult for the editors and reviewers. If your manuscript is difficult to read, the editorial office may send it back to you for revision.

  • The title page of the manuscript, including statements relating to our ethics and integrity policies:
    • data availability statement
    • funding statement
    • conflict of interest disclosure
    • ethics approval statement
    • patient consent statement
    • permission to reproduce material from other sources
    • clinical trial registration

(Why is this important? We need to uphold rigorous ethical standards for the research we consider for publication.)

  • Your co-author details, including affiliation and email address. (Why is this important? We need to keep all co-authors informed of the outcome of the peer review process.)
  • An ORCID ID, freely available at is this important? Your article, if accepted and published, will be attached to your ORCID profile. Institutions and funders are increasingly requiring authors to have ORCID IDs.)

To submit, login at and create a new submission. Follow the submission steps as required and submit the manuscript.

If you are invited to revise your manuscript after peer review, the journal will also request the revised manuscript to be formatted according to journal requirements as described below.

Review process

Manuscripts are usually assigned to one of the Associate Editors. Every submitted manuscript will undergo a rapid in-house review to determine if it is suitable for the journal and if it has priority ranking in relationship to all other manuscript being considered for publication that would justify a review by external experts. Manuscripts will be rejected without external review if they are deemed not suitable for the journal or if they have low priority ranking. Manuscripts are usually sent out for review to at least two external, expert reviewers. AJH will try to follow authors’ suggestions for possible inclusion or exclusion of specific experts in the field. Authors will receive e-mail notification concerning the final editorial decision, with comments from reviewers and editors when applicable.


Rapid Review of Manuscripts Submitted Previously to Another Journal:

As stated in the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication” ( ; Updated February 2006): “If the manuscript has been submitted previously to another journal, it is helpful to include the previous editor’s and reviewers’ comments with the submitted manuscript, along with the authors’ responses to those comments. Editors encourage authors to submit these previous communications and doing so may expedite the review process.” For manuscripts previously submitted to other journals with impact factor of 14 or greater, if authors include previous editor’s and reviewers’ comments along with their responses, the American Journal of Hematology will guarantee a rapid (within a week) in-house assessment, with three possible outcomes:

a) Acceptance or acceptance with minor changes (no additional external reviews needed);
b) Rejection;
c) Additional external review needed; in this case the authors will have the possibility of accepting the additional external review or withdrawing the manuscript.
d) When submitting a paper for Rapid Review be sure to answer the question regarding rapid review in the affirmative, upload a Word document containing the previous review comments and your detailed responses to the reviewer(s) concerns as “Supplementary Material for Review." 

If your paper is accepted, the author identified as the formal corresponding author for the paper will receive an email prompting them to login into Author Services; where via the Wiley Author Licensing Service (WALS) they will be able to complete the license agreement on behalf of all authors on the paper.

Disclosure statement

All authors must disclose any affiliations that they consider to be relevant and important with any organization that to any author's knowledge has a direct interest, particularly a financial interest, in the subject matter discussed. Such affiliations include, but are not limited to, employment by an industrial entity, ownership of stock, membership on a standing advisory council or committee, a seat on the board of directors, or being publicly associated with a company or its products. Other areas of real or perceived conflict of interest would include receiving honoraria or consulting fees or receiving grants or funds from corporations or individuals representing such corporations. This requirement will apply to every sort of article submitted to the Journal , including original research, reviews, editorials, letters to the editor, and any others, and should be disclosed at the time of submission. The simplest remedy for conflict of interest is disclosure. In the Journal , disclosure will henceforth be achieved by the inclusion of a short footnote with each published article. This information will be held in confidence while the paper is under review. It will not be shared with peer reviewers, and it will not influence the editorial decision to accept or reject the manuscript. When an article is accepted for publication, the editors will usually discuss with the authors the manner in which such information is to be presented.

Data Sharing and Data Availability

This journal expects data sharing. Review Wiley’s Data Sharing policy where you will be able to see and select the data availability statement that is right for your submission.


Articles should represent original and in-depth studies involving all aspects of clinical or laboratory investigations. While there is no length restriction for articles, authors are encouraged to limit the text to a maximum length of 5,000 words and references to no more than 100. The number of illustrations and tables should be appropriate for the data presented, but should not repeat information in the text. Research articles may contain a maximum of 4 Figures/Tables. We urge authors to consolidate figures into multi-panel ones, and/or provide additional figures/tables as on-line supplementary material.

The title page should contain the complete title of the manuscript, the names and affiliations of all authors as well as the name, address and email of the person to whom all correspondence should be addressed. While the number of authors should usually not exceed six, exceptions will be granted with adequate justification. The title page should also include the abstract word count, text word count, the number of tables and figures, a short running title, and three to six keywords to index the content.

Abstract. An unstructured abstract is required for this submission – this can take the form of a single paragraph summarising the main findings of your paper’.

Color figures. Color figures may be published online free of charge; however, the journal charges for publishing figures in color in print. Upon submission of color figures at Early View publication, you will be invited to complete a color charge agreement. You will have the option of paying immediately with a credit or debit card, or you can request an invoice. If you choose not to purchase color printing, the figures will be converted to black and white for the print issue of the journal.

Text. The text should follow the following format: Introduction, Methods, Results, and Discussion (please note that this has been recently changed so that Methods is at the top of the paper, placed in between Introduction and Results). Place Acknowledgments as the last element of the text, before references. Use subheadings and paragraph titles when possible. Authors whose first language is not English should arrange for their manuscripts to be written in idiomatic English and reviewed prior to submission by an editor facile in medical English. This will avoid disappointing delays before a paper can be sent out for review. Please see the "Submission requirements" section above for guidelines relating to language.

Patients should be referred to only by subject numbers and not with names, initials, or other potentially identifying characters. Manuscripts reporting the results of experimental investigations on human subjects must include a statement to the effect that the procedures received official institutional approval.

Use non-capitalized generic names (e.g., cyclophosphamide) for all drugs and pharmaceutical preparations. Trade names (capitalized) for appliances, etc., may be used in the Methods section, and the manufacturers should be identified by name and address.

Any tables submitted with the text should be sent/uploaded as separate Word files.

References: All references should be numbered consecutively in order of appearance and should be as complete as possible. In text citations should cite references in consecutive order using Arabic superscript numerals. Sample references follow:

Journal article:

  1. King VM, Armstrong DM, Apps R, Trott JR. Numerical aspects of pontine, lateral reticular, and inferior olivary projections to two paravermal cortical zones of the cat cerebellum. J Comp Neurol 1998;390:537-551.


  1. Voet D, Voet JG. Biochemistry. New York: John Wiley & Sons; 1990. 1223 p.

Please note that journal title abbreviations should conform to the practices of Chemical Abstracts.

For optimal production, prepare manuscript text using Microsoft Word.


When preparing digital art, please submit your figures as separate files and consider the following:


The minimum requirements for resolution are:

  • 1200 DPI/PPI for black and white images, such as line drawings or graphs.
  • 300 DPI/PPI for picture-only photographs
  • 600 DPI/PPI for photographs containing pictures and line elements, i.e., text labels, thin lines, arrows.

These resolutions refer to the output size of the file; if you anticipate that your images will be enlarged or reduced, resolutions should be adjusted accordingly.

Figures should be provided in the manuscript or in one of the following file format: .png, pdf, or jpeg.


For the editorial review process, color images may be submitted in RGB color; upon acceptance, CMYK color will be required. Delivery of production-quality files early in the review process may help facilitate smooth and rapid publication once a manuscript has been accepted.

A legend must be provided for each illustration and must define all abbreviations used therein. Legends should be placed at the end of the manuscript text file or below each figure. Please be sure to submit your figures as separate files.

Authors are encouraged to submit color illustrations that highlight the text and convey essential scientific information. All color figures will be reproduced in full color in the online edition of the journal at no cost to authors. Authors are requested to pay the cost of reproducing color figures in print. For best reproduction, use bright, clear colors. Dark colors against a dark background do not reproduce well; please place your color images against a white background wherever possible. Please contact [email protected] for further information.

Critical Reviews

Reviews of important and timely subjects can be invited by the editorial board or submitted independently. In the latter case, it is usually helpful for the corresponding author to consult the Editor-in-Chief prior to submission. Reviews should focus on the critical aspects of a subject, linking established knowledge to areas that remain controversial or unanswered. Reviews should normally comprise less than 6,000 words, contain an unstructured abstract of 100 words or less, and use fewer than 150 references; illustrations and tables should be used only to provide summaries or a synthesis of ideas and/or data not included in the text.


Correspondence should usually be in reference to previously published manuscripts in American Journal of Hematology . However, correspondence relating to important and timely publications or topics from other sources may also be appropriate. Brief descriptions of interesting laboratory or clinical observations may also be appropriate. Correspondence to the Editor should be no more 1,500 words, no more than 6 references and one table/figure. No abstract is required. The introduction must include “To the Editor:”.


Commentaries are usually invited but may be submitted independently after consultation with the Editor-in-Chief. Please limit the text to 2,500 words and fewer than 10 references. Commentaries should focus on a controversial subject arising from a recently published American Journal of Hematology manuscript, but they may also focus on independent and timely topics of relevance to the journal’s readership. Illustrations and Tables are allowed only if they highlight or clarify points made in the text. Commentaries will be reviewed and may require changes or be rejected. No abstract is required.

Solving Clinical Problems in Blood Disease/Clinical Problem Solving 

The format of this case presentation should be similar to that used in the Clinical problem-solving articles of the New England Journal of Medicine (see as an example: Prasad M et al. New Engl J Med 2006 355:2468-2473 ). These articles should reproduce the step-by-step process used by clinicians dealing with novel and/or unusually challenging clinical presentations of hematological diseases. Clinical information must be presented in stages (boldface type), followed by the clinical reasoning of the physician taking care of such a patient, and a final discussion of the case as it relates to disease pathophysiology, complications, treatment, and treatment outcomes. Manuscript length should be no more than 2,500 words, with no more than 25 references. No abstract is required. Please submit these in the ‘Clinical Problem Solving’ article category in the submission site. 

Images in Hematology
We believe that the discipline of hematology lends itself particularly well to visual case presentations. The purpose of this section of the Journal , therefore, is to present an interesting visual description of a defined hematological condition. The image may consist of a single photo or a series of photos that, when grouped together, give a visual description of the specific hematological entity. It is expected that the submitting authors(s) will supplement the visual "Image" with brief text as necessary to tell the full story. Whenever appropriate, we will publish the images in full color. No abstract is required.

Diagnostic Imaging in Hematology

A variety of techniques (X-rays, CT scans, MRI, Nuclear Medicine scans and ultrasound) are routinely utilized in the diagnosis and treatment of hematological diseases. The purpose of this section of the Journal is to provide images of techniques which provide relevant diagnostic and clinical information for physicians managing patients affected by Blood Diseases. These entries should not include an abstract.

Annual Updates in Hematological Malignancies 
These are invited submissions; any submissions in this category must be cleared by the editor first. If you wish to submit in this category, please contact the editorial office. A structured abstract is required for this submission.

Updates in Clinical Trials for Hematological Diseases
These are invited submissions; any submissions in this category must be cleared by the editor first. If you wish to submit in this category, please contact the editorial office. An unstructured abstract is required for this submission – this can take the form of a single paragraph summarising the main findings of your paper.


Please consult with the Editor-in-Chief before submission. This feature should include a discussion of a specific laboratory test/parameter that is relevant for hematologist/oncologists and for any clinicians dealing with blood disorders. It should summarize technical specifications and issues, clinical performance and pitfalls, and provide evidence of sensitivity and specificity, particularly discussing disease conditions if available. Manuscript length should be no more than 2,500 words with no more than 40 references.


Reviews of books, films, or other media formats
Reviews of books, films, or other media formats relevant to the scientific or clinical practice of medicine, with particular importance to hematology/oncology, may be invited or submitted independently. In the latter case, please consult with the Editor-in-Chief prior to submission.

Meeting reports and supplements
Concise summaries of meetings that have important information to convey to the readers of American Journal of Hematology are welcomed, but consultation with the Editor-in-Chief should occur before submission. Summaries should emphasize the issues discussed at the meeting along with an explanation of how they are important or controversial. Summaries should be less than 2000 words. Illustrations and tables may be included but only when they add significantly to the text content. More extensive reports with manuscripts from the speakers are also welcomed, but early consultation with the Editor-in-Chief must take place in order to determine the type and number of manuscripts to be published, the review process, and the procurement of additional funding if required.
