Rationale for implementing a modest publication fee for peer-reviewed manuscripts

For over 12 years we have published Medical Educations Online (MEO) without charging for access or charging authors for publishing. We operated the journal largely on volunteer effort and occasionally small subsidies for hosting the journal and purchasing a domain name.  Approximately a year ago, we added Google Adsense  advertising to the web site with the hope of obtaining enough funding to cover the cost of copyediting as well as hosting the journal.  While the funds we obtain from the advertising provided more than enough income to cover the cost of hosting the journal on a commercial server the remaining funds  are not adequate for covering the costs of copy editing or  fees for services we feel will significantly enhance the journal . These include

Implementing a modest publication fee of $100 USD has been a very hard decision for us but I believe it is essential for maintaining the quality of the journal as well as improving the journal articles’ accessibility and stature. A tremendous amount of work goes into publishing a quality scholarly journal and it is virtually impossible to do it on volunteer effort alone. Although charging publication fees is not ideal, it is far better than charging reader for accessing the material in MEO via subscription or other fees.  Please note as well that:

We always appreciate your feedback and thoughts about the journal at editor@med-ed-online.org and hope you will understand the need for the implementation of this fee.
