I recently was alerted to the existence of an Open Access (OA) publisher that I had not heard of before: MDPI. Their name stands for “Multidisciplinary Digital Publishing Institute” and they are based in Switzerland. They publish more than 70 journals and all journals are members of the Committee on Publication Ethics (COPE). They started in 1996 and expanded slowly but since 2009 have launched quite a few new titles. The oldest title has published more than 5,000 articles, and 18 of their titles have published more than 200 articles.
MDPI publishes on quite a range of subjects – sampling the title list I find aerospace, agriculture, antibodies, crystals, entropy, genes, environment, molecular sciences, materials, remote sensing, and viruses. They have quite a few biomedical titles, though many of these are new and hence small at present.
Their fees vary quite a bit. Articles in new journals are published free of charge, but otherwise the fees range from CHF 300 to CHF 1800.
Are they a reputable publisher? The answer seems to be ‘yes’, though perhaps their marketing can be overzealous. MDPI is a member of OASPA, which suggests strongly that they are reputable. Their journals are not high impact journals maybe but it seems they are serious publishers wanting to serve science.
