It seems that each week I get invited to submit a manuscript to some open access journal. Then comes the reality, and it is a massive publishing fee. Some journal have the open access as an "option", and it still is possible to submit a manuscript to this journal for a print version paper. So far there is no fee, but if your manuscript includes color figures or maps, then it often means an additional $500-$750 fee per color image. Where should I get the money to pay for such fees? Grants? Should I ask my university to help out?
