Generally, when doing research one thing everyone needs is access to the stuff they want. There is a lot of different stuff and a lot of different ways to access that stuff. Here are some pointers to ways you can gain access to what you need.

First, get access to your local libraries. Libraries have a lot of stuff and with a single access point, your library card with your barcode and PIN, you can access the library's stuff remotely and get stuff when you visit. The Portland metro area, Washington, and Oregon are very user-friendly library communities. Don't limit yourself to thinking you can only use one library system because you live in only one place. Most of our libraries are linked together by consortia agreements. That's a fancy way of saying that they partner together so you can use as many libraries as you need. So check out the library borrowing policies to see how you can get a card there. A library card, barcode, and PIN also gives you remote access to that library's databases - where those journal articles you're looking for live.

OK, so maybe you can get library access by other means. Do you work at or go to another school? Do you have a healthcare provider's license? Many libraries have partner and professional agreements that qualify you for a library card, barcode and PIN. Then you can access those libraries and, perhaps, their databases too.

OHSU if you have healthcare provider's license, you can use OVID databases from home!
