I know of Beilstein Journal of Organic Chemistry : http://www.beilstein-journals.org/bjoc... - Anna Croft

The majority of OA journals do not charge author-side fees -- see http://blogs.law.harvard.edu/pamphle... and http://www.earlham.edu/~peters... and http://www.sennoma.net/main... - Bill Hooker

Also of possible interest: a 2005 study showed that 75% of toll-access journals DO charge author-side fees (http://www.alpsp.org/ngen_pu...), and I have tried to estimate the average author-side fee charged by TA journals (see http://www.sennoma.net/main...) -- the figure I arrived at is $909 - $1136 per article, which is consistent with the handful of self-reported figures I have been able to find. - Bill Hooker

Remember that the author-side income is in addition to subscription income for these TA journals; I updated a 2004 study by Philip Davis and came up with an estimated average subscription cost per article of $970 - $1750. My data point to the upper figure being the more reliable, so that gives us $1879 to $2886, with a better guess of $2659 to $2886, as the likely per-article income (not including such things are reprints or advertising) at TA journals. Details here: http://www.sennoma.net/main... - Bill Hooker

That is roughly consistent with the charges levied by most hybrid programs (TA journals which will, for an extra fee, make an article OA), most of which cost around $3000. - Bill Hooker

Some good info on waivers at PLoS, BMC and Hindawi here: http://www.arl.org/sparc... - Bill Hooker

Just noticed about this journal : It is free to submit articles to Bioscience Education; no author, colour or page charges. http://www.bioscience.heacademy.ac.uk/journal... - Khader Shameer

thanks a lot, Anna, Bill and Khader :-) - Claudia Koltzenburg
