In your searches in EconLit, the portals listed above, and think tanks, you may encounter citations to working papers. Contact Kristin if you want to access these -- sometimes it can be tricky, but don't assume you have to buy them.
The NBER working paper series is an important resource in economics. Though the library does not subscribe, it is possible to request specific working papers through Interlibrary Loan. Once in the ILL system (login from the library's home page), use the "Photocopy Request" option. Enter "NBER Working Papers Series" as the title, the NBER document number (e.g. w5741) as the Volume, the month and year, and just type "all" in the Inclusive Pages field. The ISSN is important to include, which is 08982937. The rest is self explanatory. If all goes well, you will receive an e-mail in a week or so with a link to an electronic version of the paper.
