The top five resources for this subject are:
Students in the Master of Arts in Policy Studies (MAPS) program produce capstone projects that may be viewed online via the University of Washington Libraries' digital archive. Projects from 2011 to present are accessible. The most recent submissions may be viewed here: MA in Policy Studies ResearchWorks.
Capstone projects from 2010 and earlier are available in print only on the third floor of the Campus Library. They are all located under the call number H97.4. You can also find them in UW Libraries Search by entering the keywords "policy and capstone" and then limiting your results to the UW Bothell/CC Library.
The MAPS program is just four quarters long - before you know it, you'll be graduated and on your way to a job or another institution. With that transition comes the fact that you'll lose some, but not all, access to materials and resources at the UW Bothell Campus Library. More more details on what you can and cannot access after graduation, read this FAQ: Can I still use the library after I've graduated?
