Permanency of articles
BioMed Central has taken steps to ensure that all open access articles published by BioMed Central are deposited in a number of safe open access archives. Should BioMed Central be sold, or fail, open access to the articles published is guaranteed to continue via those archives. If and when a change of ownership should be considered, BioMed Central's Board of Trustees will be asked to judge and advise whether sufficient guarantees to continue a policy of unconditional open access for research articles are being offered and agreed by any prospective new owner. BioMed Central will not enter into a change of ownership agreement unless the Board of Trustees accepts these guarantees.
In addition, once an article has been published, we do not allow it to be changed, leading to the following policies.
Article corrections and retractions
Corrections to or retractions of published articles will be made by publishing a correction or retraction note and without altering the original article in any way other than to add a prominent link to the note. In this way, the original article remains in the public domain and the subsequent correction or retraction will be widely indexed.
The preservation of scientific research is a cornerstone of science and as such we will use our best efforts to ensure that material published by BioMed Central is preserved and remains available for access. However in the exceptional event that material is considered to infringe certain rights or is defamatory we may have no option but to remove that material from our site and those sites on which we have deposited the material in question.
BioMed Central therefore reserves the right to cease to make available articles that it has been advised are potentially defamatory or that infringe any intellectual property right, or are otherwise unlawful.
Where this occurs the article will remain indexed. However in place of the article or header the following will appear:
"BioMed Central regrets that this article is no longer available to avoid threatened legal claims".
