I'm going to send manuscript for publication in IEEE Transactions. Some parts of this manuscript were published earlier in little-known journals (in Russian). But in general manuscript is significantly different from previous papers. Should I upload previous papers as a ‘Previous Published Version(s)’, and upload summary of differences?
UPD: I found the following in ScholarOne Manuscripts (IEEE Transactions manuscript submission site): "Has any portion of your paper been published elsewhere? If yes, please include your original paper and a brief summary of your changes. New material must be added before submitting the manuscript to this journal.". So, I should upload previous published versions?
