What is Open Access?
Open access (OA) is the practice of providing unrestricted access via the Internet to peer-reviewed scholarly research. Open access journals provide 'gold' open access, meaning immediate open access to all of their articles on the publisher's website. 'Gold' open access for individual articles is funded by authors, institutions, funders, or sponsors who pay an open access article-processing charge (APC) after acceptance.

What types of articles will HemaSphere publish?
HemaSphere publishes Original Research, Reviews, Guidelines, and shorter articles including letters, perspectives, ​editorials, as well as HemaTopics (authored by our Scientific Editors), and HemaPolicy papers. To enhance quality, readability, and to be more competitive with other leading scientific journals, all manuscripts must conform to word-count standards for article length, references, and number of figure pieces. Please visit the Instructions for Authors for more information.

How will readers know articles are open access?
All open access articles are marked with an icon bearing 'Open' on the full-text and PDF formats of the published work, and information on the type of creative commons license will be available on all article formats and listed in the article metadata.

Who retains copyright of the open access articles?
Authors retain copyright for their article. Open access articles will be freely available to read, download and share from the time of publication. HemaSphere provides authors the choice of applying any of the Creative Commons 4.0 licenses defined below, to be determined after acceptance.
