Osteopathic Medicine and Primary Care (OMPC) enters its fourth year of operation in 2010 under the umbrella of BioMed Central. Osteopathic Medicine and Primary Care strives to promote and advance research and scholarly work within the fields of osteopathic medicine and primary care. In so doing, OMPC welcomes submissions from clinicians within both the osteopathic and allopathic medical professions, and from other professionals having interests in primary care, including health care delivery, public health, and evidence-based medicine. Osteopathic Medicine and Primary Care offers fair and expeditious peer review (mean time from submission to publication, 118 days), retention of copyright for authors, unlimited online distribution and access without charge to readers, indexing in PubMed, and archiving in PubMed Central. In 2010, there will be an increased availability of waivers or discounts of article processing charges via several mechanisms for eligible authors who submit qualified manuscripts, especially in the field of primary care.
