About the Journal

Focus and Scope

Hypothesis is an international peer-reviewed journal that provides a venue for original research and research-related content, including research studies and reflections on the process in order to encourage a broader, reflective conversation among MLA members, medical librarians, and librarians interested in research. There is no requirement to be an MLA or MLA Research Caucus member in order to submit manuscripts to the journal; however, the editors reserve the right to evaluate submission pertinence for our readers.

Manuscripts are reviewed for possible publication and will be evaluated based on criteria suited to the type of content. Assuming that works submitted meet the criteria, they are published with the understanding that they have not been published elsewhere, including in online formats. As an exception, research or other content that has been presented at a conference will be accepted, with the requirement that authors add a note to that effect in the manuscript. For questions, please contact the editors at MLARSHypothesis@gmail.com.

Hypothesis is published by the Research Caucus of the Medical Library Association. This journal is hosted and supported by IUPUI University Library.

Peer Review Process

For research papers, Hypothesis uses a double-blind peer-review process, in which reviewers do not know the identity of the author and the identity of manuscript reviewers is not revealed to the author. Peer review will be based on how well submitted work has followed evidence-based guidelines for research. The rubric for review is provided for your use as a checklist. If you are a new researcher, you are encouraged to contact a research mentor through MLA (see Professional Development / Find or Become a Mentor, or http://www.mlanet.org/p/cm/ld/fid=45).

Publication Frequency

Hypothesis is published online twice per calendar year: Spring/Summer and Fall/Winter. Hypothesis, however, accepts submissions year round. Learn more about our Submission categories and contact the Co-Editors, if you have any questions or concerns.


Hypothesis is indexed in CINAHL (Cumulative Index to Nursing and Allied Health Literature), LISSA (Library and Information Science Source), and LISTA (Library, Information Science & Technology Abstracts).
