Submission of papers
The British Journal of Haematology invites papers on original research in clinical, laboratory and experimental haematology. All papers should include only new data which have not been published elsewhere. All authors are expected to disclose any commercial affiliations as well as consultancies, stock or equity interests and patent-licensing arrangements that could be considered to pose a conflict of interest regarding the submitted article. Specifics of such disclosures will remain confidential. If appropriate, general statements in the acknowledgements regarding such disclosures may be recommended by the editors.

Wiley Blackwell will dispose of all hardcopy or electronic material submitted two issues after publication.

NEW: Pre-submission English-language editing

Authors for whom English is a second language may choose to have their manuscript professionally edited before submission to improve the English. A list of independent suppliers of editing services can be found at All services are paid for and arranged by the author, and use of one of these services does not guarantee acceptance or preference for publication.

Ethical policy and guidelines
BJH encourages its contributors and reviewers to adopt the standards of the International Committee of Medical Journal Editors. BJH will not consider papers that have been accepted for publication or published elsewhere. Copies of existing manuscripts with potentially overlapping or duplicative material should be submitted together with the manuscript, so that the Editors can judge suitability for publication. The Editors reserve the right to reject a paper on ethical grounds.

Disclosure and competing interests statement
Authors are required to disclose financial interests in any company or institution that might benefit from their publication. A competing interest exists when a primary interest (such as patients’ welfare or the validity of research) might be influenced by a secondary interest (such as financial gain or personal rivalry).

It may arise for the authors of a British Journal of Haematology article when they have a financial interest that may influence their interpretation of their results or those of others. Financial interests are the easiest to define and they have the greatest potential to influence the objectivity, integrity or perceived value of a publication. They may include any or all, but are not limited to, the following:

• Personal financial interests: Stocks or shares in companies that may gain or lose financially through publication; consultant fees or fees from speakers bureaus other forms of remuneration from organisations that may gain or lose financially; patents or patent applications whose value may be affected by publication.
• Funding: Research support from organisations that might gain or lose financially through publication of the paper.
• Employment: Recent, present or anticipated employment of you or a family member by any organization that may gain or lose financially through publication of the paper. Any such competing interest that authors may have should be declared. The aim of the statement is not to eradicate competing interests, as they are almost inevitable. Papers will not be rejected because there is a competing interest, but a declaration on whether or not there are competing interests will be added to the paper.
• Patent rights
• Consultancy work.

All authors must disclose competing interests, or state “none” via the Journal's ScholarOne Manuscripts website.

All sources of funding must be disclosed in the Acknowledgments section of the paper. List governmental, industrial, charitable, philanthropic and/or personal sources of funding used for the studies described in the manuscript. Attribution of these funding sources is preferred.

• This work was supported by a grant from the National Institutes of Health, USA (DKxxxx to AB).
• This work was supported by the Crohn's and Colitis Foundation of Canada (grant to AB and CD).
• This work was supported by a grant from Big Pharma Inc. (to AB) and equipment was donated by Small Pharma Inc. EF received a graduate studentship award from the University of xxxxx.

For papers where there are no competing interests, all authors must include the statement ‘Competing interests: the authors have no competing interests.’

We will also ask reviewers to provide a statement of competing interests.

All authors must fulfil the following three criteria:

• Substantial contributions to research design, or the acquisition, analysis or interpretation of data,
• Drafting the paper or revising it critically, and • Approval of the submitted and final versions. In the Acknowledgments section of the paper all authors, must indicate their specific contributions to the work described in the manuscript. Some examples include
• X performed the research
• Y designed the research study
• Z contributed essential reagents or tools
• A analysed the data
• B wrote the paper.

An author may list more than one contribution, and more than one author may have contributed to the same element of the work. E.g. ‘A performed the research, A and C analysed the data and wrote the paper, E contributed the knockout mice for the study and G designed the research study and wrote the paper’.

Role of professional medical writers in peer-reviewed publications
Please ensure that you follow the guidelines by the European Medical Writers Association on the role of medical writers. The guidelines emphasise the importance of respecting widely recognised authorship criteria, and in particular of ensuring that all people listed as named authors have full control of the content of papers. The role of professional medical writers must be transparent. Please name any professional medical writer among the list of contributors to any article for British Journal of Haematology (not only original research papers), and specify in the acknowledgements and statement of competing interests for the article who paid the writer. Writers and authors must have access to relevant data while writing papers.

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.

Research papers
The majority of papers published in the Journal report original research into scientific and clinical haematology. All papers are subject to review and authors are urged to be brief; long papers with many tables and figures may require shortening if they are to be accepted for publication.

Short reports
Short reports which offer significant insight into scientific and clinical haematological processes may be published. They may include up to 1500 words of text, two figures or tables or one of each, and up to 15 references. A summary of up to 100 words should be followed by continuous text, subdivided if appropriate. Short reports could include important preliminary observations, short methods papers, therapeutic advances, and any significant scientific or clinical observations which are best published in this format. Publication of initial results which will lead to more substantial papers will generally be discouraged. Although submission of case reports is not encouraged, these will be considered if the report includes novel scientific material or is of especial clinical interest. Authors will receive proofs.

Annotations and reviews
These are normally invited contributions but suitable papers may be submitted to the Editor for consideration for this purpose. Previous issues of the Journal should be consulted for style of contribution and length.

Letters to the Editor
Correspondence which relates to papers which have recently appeared in the Journal may be published. The Editor reserves the right to invite response from the original authors for publication alongside. In addition, letters dealing with more general scientific matters of interest to haematologists will be considered. Letters should be as short as possible (but no more than 1000 words of text, two figures or tables or one of each, and up to 10 references).

Correspondence to the journal is accepted on the understanding that the contributing author licences the publisher to publish the letter as part of the journal or separately from it, in the exercise of any subsidiary rights relating to the journal and its contents.

Images in Haematology
Authors can submit for consideration an illustration (or, where appropriate, two or more related images) which is interesting, instructive and visually attractive, with a few lines of explanatory text and a maximum of six contributors. If there are more than three authors then the corresponding author should outline the contribution of each author that justifies their inclusion. The images (e.g. a clinical photograph, radiology, cytology, histology, a laboratory test) should be submitted in a digital format online at High-quality glossy prints, transparencies, or digital files (see should be sent to the BJH Office on acceptance. Because of space constraints, there are usually no references in the 'Images' section. However, it is at the discretion of the Images Editor to accept one reference if it appears essential to the contribution in question.

Information about scientific meetings that are likely to be of general interest to readers of the Journal may be published at the discretion of the Editor. These should be sent to the Editor as early as possible prior to the event. Text should be as concise as possible, with a maximum of 150 words.

Preparation of manuscripts
Manuscripts should be formatted with wide margins and bear the title of the paper with the name and address of the author(s), together with the name of the hospital, laboratory or institution where the work has been carried out. Authorship should be restricted to individuals who have made a significant contribution to the study. The name, full postal address and e-mail address of the author to whom readers should address correspondence and reprint requests should be given on the first page; this will appear as a footnote in the journal and the publishers will send proofs to this author at the given address unless contrary instructions are written on the manuscript. Correspondence during the peer-review process will be with the author indicated during submission. A running short title of not more than 60 characters and spaces should be included. An informative summary of not more than 200 words must be included at the beginning of the paper and supplied when prompted during the online submission process. Papers should normally be divided into summary, introduction, methods (and/or materials), results, discussion, acknowledgements and references. SI units should be used throughout. Human DNA, gene, protein, and DNA restriction and modification enzyme nomenclature should be standardized as follows:

1) Human genes and alleles should be italicized capitals;

2) Human protein designations are the same as the gene symbol (i.e., written in upper case), but not italicized;

3) When distinguishing between mRNA, genomic DNA and cDNA, the relevant term should be given after the gene symbol, e.g. BCL2 cDNA;

4) D numbers should be as described in the Guidelines for Human Gene Nomenclature (Wain et al, 2002, Genomics, 79, 464-470;

5) Nomenclature for DNA restriction and modification enzymes and their genes should follow Roberts et al (2003, Nucleic Acids Research, 31, 1805-1812;

The Editor reserves the right to make textual changes.

Five keywords must be supplied after the summary.

The main categories of headings are side capitals, side italics and shoulder italics. If necessary, small capitals may be used for subsidiary main headings. For examples see articles in a recent issue of the Journal.

Illustrations should be referred to in text as, e.g., Fig 2, Figs 2, 4–7, using Arabic numbers. Individual figure files should bear a reference number corresponding to a similar number in the text, prints should be marked on the back with the name(s)of the author(s) and the title of the paper. Where there is doubt as to the orientation of an illustration the top should be marked with an arrow. Photographs and photomicrographs should be unmounted glossy prints and should not be retouched.

Where printed, diagrams should be on separate sheets. Lines should be of sufficient thickness to stand reduction. Each illustration should be accompanied by a legend clearly describing it. In the full-text online edition of the journal, figure legends may be truncated in abbreviated links to the full-screen version. Therefore the first 100 characters of any legend should inform the reader of key aspects of the figure.

It is the policy of the Journal for authors to pay the full cost for the reproduction of their colour artwork. Therefore, please note that if there is colour artwork in your manuscript when it is accepted for publication, Wiley-Blackwell require you to complete and return a colour work agreement form before your paper can be published. This form can be downloaded as a PDF from the internet here.

Once completed, the original hard copies of the form should be posted to the following address:

Customer Services (OPI)
John Wiley & Sons Ltd, European Distribution Centre
New Era Estate
Oldlands Way
Bognor Regis
West Sussex
PO22 9NQ
United Kingdom

If you are unable to access the internet, or are unable to download the form, please contact the Editorial Office and they will be able to email or fax a form to you. Any article received by Wiley Blackwell with colour work will not be published until the form has been returned.

Electronic artwork
We would like to receive the artwork accompanying accepted manuscripts in electronic form. Please save vector graphics (e.g. line artwork) in encapsulated Postscript format (EPS), and bitmap files (e.g. half-tones) in tagged image file format (TIFF). Detailed information on our digital illustration standards is available at

Tables should be as few as possible and should include only essential data; they should be printed on separate sheets and should be given Roman numerals.


We recommend the use of a tool such as Reference Manager for reference management and formatting. Reference Manager reference styles can be searched for at: http// Only papers closely related to the author's work should be cited. References should be made by giving the author's surname with the year of publication in parentheses. Where the reference contains more than two authors it should be given at each mention in the text with only the first surname plus et al, e.g. Jones et al (1948). If several papers by the same author (s) and from the same year, or by the same author but different subsequent authors in the same year are cited, a, b, c, etc., should be put after the year of publication, e.g. Jones et al (1948a, b). All references should be brought together at the end of the paper in alphabetical order, with all authors, titles of journals spelt out in full, and with both first and last page numbers given. The style to be used is that of any recent issue of the Journal.

Supporting information
Supporting Information can be a useful way for an author to include important but ancillary information with the online version of an article. Examples of Supporting Information include additional tables, data sets, figures, movie files, audio clips, 3D structures, and other related nonessential multimedia files. Supporting Information should be cited within the article text, and a descriptive legend should be included. It is published as supplied by the author, and a proof is not made available prior to publication; for these reasons, authors should provide any Supporting Information in the desired final format.

Early View
The British Journal of Haematology is covered by Wiley Blackwell's Early View service. Early View articles are complete full-text articles published online in advance of their publication in a printed issue. Articles are, therefore, available for publication as soon as they are ready, rather than having to wait for the next scheduled print issue. Early View articles are complete and final. They have been fully reviewed, revised and edited for publication, and the authors' final corrections have been incorporated. Because they are in a final form, no changes can be made after online publication. The nature of Early View articles means that they do not yet have volume, issue or page numbers, so Early View articles cannot be cited in the traditional way. They are, therefore given a Digital Object Identifier (DOI), which allows the article to be cited and tracked before it is allocated to an issue. After print publication, the DOI remains valid, and can be continued to be used to cite and access the article.

Free access to the final PDF offprint or your article will be available via Author Services only. Please therefore sign up for author services if you would like to access your article PDF offprint and enjoy the many other benefits the service offers. Paper offprints of the printed published article may be purchased if ordered via the method stipulated on the instructions that will accompany the proofs.

The British Journal of Haematology is covered by Current Contents, Chemical Abstracts, Current Clinical Cancer, CABS, ISI/BIOMED, Science Citation Index and ASCA.
