POPSGreek Bibliography of the 19th century "The retrospective Greek national bibliography of the 19th century is a collective work, as is every ambitious bibliography project, based on the long preparatory work undertaken by distinguished scholars and obscure bibliographers. Its foundations were lain by the three-volume Greek Bibliography 1800-1863, by Dimitrios Ghinis and Valerios Mexas (Athens, Academy of Athens, 1939-1957), in combination with successive series of addenda over the same period, which were introduced by C. Th. Dimaras from the pages of the journal Eranistis (a periodical publication of the Society for the Study of the Greek Enlightenment). The work was later taken up mainly by the Tetradia Ergasias of the Institute for Neohellenic Research of the National Hellenic Research Foundation."

POPSNeo-Latin texts online Very likely I'm the only person on Clipmarks quite geeky enough to want to know about this, but here you go. It's a massive bibliography of full-text neo-Latin sources, apparently mostly 15th- and 16th-century published works. My Latin's pretty rusty but if there are any late-medievalists out there maybe you can use this.
