How To Order

All of our ordering is now handled by the Montana Bureau of Mines and Geology (MBMG). Click Here to access the MBMG online catalog. You'll be offered the choice of "Main Catalog Search" or "Browse the Catalog." In either case, to find specific TRGS and Northwest Geology publications, select "Northwestern Geology" or "Tobacco Root Geological Society" on the publication-type drop-down menu (note that TRGS is at the very bottom of the listings). You can then select the publications you want to order.

Be sure to note that four TRGS publications, listed below, are MBMG Special Publications (SP), so to find and order them you need to select "Special Publications" on the drop-down menu for publication type. You can also search the entire MBMG publications database using keywords, author, title, year, and other criteria—go to the "Main Catalog Search" option on the main database page.

All TRGS publications are available; those that are out of print are provided through photocopying, and this is noted in the information provided through the MBMG database.
