Three examples, from 3 different publishers:
1) A viewing today of the 2009 Reviews archive of Nature Reviews Cancer revealed 4 articles, in the archive for April 2009, where the full text “is available free as a special feature to registered visitors“. They are:
Microenvironmental regulation of metastasis by Johanna A Joyce and Jeffrey W Pollard; Learning therapeutic lessons from metastasis suppressor proteins by Steven Christopher Smith and Dan Theodorescu; Transitions between epithelial and mesenchymal states: acquisition of malignant and stem cell traits by Kornelia Polyak and Robert A Weinberg; Metastasis: from dissemination to organ-specific colonization by Don X Nguyen, Paula D Bos and Joan Massagué.
Genomewide Association Studies and Human Disease by John Hardy and Andrew Singleton; Genetic Risk Prediction — Are We There Yet? by Peter Kraft and David J Hunter; Genomewide Association Studies — Illuminating Biologic Pathways by Joel N Hirschhorn; Common Genetic Variation and Human Traits by David B Goldstein; Genomewide Association Studies of Stroke by M Arfan Ikram and 45 co-authors; Crohn’s Disease, Autophagy, and the Paneth Cell by Daniel J Klionsky.
3) A viewing today of the Site Map for Cell Press journals led me to the Archive section for the journal Cancer Cell. I then browsed the current issue (7 April 2009, Volume 15, Issue 4). One “Featured Article” was labeled “Free“. It was: Rb Regulates DNA Damage Response and Cellular Senescence through E2F-Dependent Suppression of N-Ras Isoprenylation by Awad Shamma and 7 co-authors (page 255). However, when the same article was accessed via it’s digital object identifier (DOI), at: dx.doi.org/10.1016/j.ccr.2009.03.001, I could not obtain access to the free full text.
However, when I checked access to the other 12 articles in this same issue, I was able to access the free full text of all of them. One example: Lessons Learned from the Study of JunB: New Insights for Normal and Leukemia Stem Cell Biology by Monica L Guzman and Craig T Jordan (page 252). Again, access via the DOI (dx.doi.org/10.1016/j.ccr.2009.03.008) didn’t provide a route to the free full text.
Comment: Which of the examples listed above will be Gratis OA on an ongoing basis? I’ll plan to check the links included in this post at later dates, to try to obtain an answer to this question.
