I've been asked how I can afford to go to so many library/archive conferences and the answer is: I can't. I am very selective about the conferences I decide to attend, I give preference to those in which I will be presenting or at least, would consider presenting at at a future date, and then I only go if I can obtain a scholarship to pay most of, if not all, my expenses.
Next week I'll be in New Mexico presenting a paper at the Institute for American Indian Research's (IfAIR) Indigenous Graduate Students Conference, Planting the Seeds of Our Research. If I had not been awarded a very generous scholarship which pays airfare, hotel, and meals, I would not be attending.
Next month I'll be on a panel discussing the Protocols for Native American Archival Materials at the Northwest Archivists Conference in Alaska. I'm paying for this trip by using some scholarship funds I was awarded. Again, if it weren't for that scholarship, I would not be going to this conference.
If you are seriously interested in attending conferences then pick a few you think you would really enjoy and which fit in with your career goals and interests and begin looking for ways to finance them. There are many scholarship and grant opportunities if you look and are willing to apply.
