This type of involvement must also be disclosed to the Editor-in-Chief in the Cover Letter.

Blood RCI Commentaries

The Editors invite experts in the field to write brief commentaries introducing and placing into context selected primary research articles.

Perspective

Perspectives are articles discussing significant topics and controversies relevant to hematology, generally from a more personal or opinion-based standpoint than a Review Article. Interested authors should first submit a presubmission inquiry using our online submission system to allow the editors to evaluate the suitability of the proposed subject matter. The length of the article should not exceed 4,000 words; the abstract must not exceed 250 words; we recommend a limit of 100 references. We wish for Perspectives to be written by experts who are personally committed to writing the manuscript, and therefore limit authorship to a maximum of 3 authors. Typically, Perspectives should state the topic and background information concisely, discuss opposing viewpoints, and make recommendations for further investigations or actions.

Pharmaceutical or medical device company employees and medical writers supported by a pharmaceutical or medical device company are not permitted to have any role in writing Review or Perspective articles. The use of editing services for non-English speakers is permissible, but it must be disclosed. Please direct any questions regarding this policy to the Editor-in-Chief prior to submission.

Review Article

Review Articles are welcomed by the Journal and are generally solicited by the Editor-in-Chief; authors wishing to submit an unsolicited Review Article are invited to submit a presubmission inquiry prior to full submission in order to screen the proposed topic for relevance and priority, given other review articles that may already be in preparation. Review Articles should focus on recent scientific or clinical advances in an area of broad interest to those in the field of hematology. Such articles must be concise and critical and should include appropriate references to the literature. All Review Articles, including those solicited by the Editors, are rigorously peer reviewed before a final publication decision is made.

Review Articles should not exceed 4,000 words in length; the abstract must not exceed 250 words; submission of a visual abstract is optional; we recommend a limit of 100 references. These articles should have no more than 3 authors. Permission to include more than 3 authors must be granted by the Editor-in-Chief. The use of tables and color figures to summarize critical points is encouraged.
