Bees of Northwestern America Technical Bulletins
Are these technical bulletins still available for PDF download? There is some overlap in bees species between OR and northern Arizona. I have a few and they are helpful in identifying bees. Thank you

Thank you for your question. I just did a few minutes of web search and found: https://ir.library.oregonstate.edu/concern/technical_reports/c247dt440 https://ir.library.oregonstate.edu/concern/technical_reports/3484zj261 If there are other species you want, I suggest you contact the Archives at ScholarsArchive@OSU. Good luck!
