Being the "mother distributions" of all types of two-parton correlation functions, generalized TMDs (GTMDs) have garnered a lot of attention. We address the important question of how to access GTMDs in physical processes. Recently, we have shown that quark GTMDs can in principle be probed through the exclusive pion-nucleon double Drell-Yan process, where the focus was on two particular GTMDs only. We now present new results concerning access to the remaining quark GTMDs in the same process. We also extend our study to the nucleon-nucleon double Drell-Yan process which is sensitive to chiral-odd GTMDs. Moreover, we show that GTMDs for gluons can be explored via exclusive double $\eta_c$ production in hadronic collisions.
