All, What follows is a list of the OCLC record numbers of the Geologic Folios (1894-1945) by USGS. Except when noted, I have upgrade all the records to current standards. I did my best to be consistent. The first part of list is of the "Library editions" (the large folios). After this is a few variations of those editions. The last part is of the "Field editions" (the pocket folios). To the best of my knowledge, there were very few Field editions published. I hope this list and the upgraded records will help you. --Christopher JJ Thiry Map Librarian (and cataloging fool) Colorado School of Mines [log in to unmask] *************************************** GEOLOGIC FOLIOS by USGS Records updated and compiled by Christopher J.J.
