The Ask-a-Librarian service is great but too slow because of staff cuts. You might try doing your own search if your home library can do an inter-library loan with Washington State Library. I just finished an obit search in the Sedro-Woolley newspaper for 1915. Here is a step-by-step of how I found the microfilm you will need:
1. Go to http://www.sos.wa.gov/library/catalog.aspx
to search the library's catalog.
2. Read down the left hand side for SEARCH SPECIAL COLLECTIONS and click on the WASHINGTON NEWSPAPERS button.
3. In the SEARCH FOR window, scroll to CITY or COUNTY.
4. In the SEARCH WORDS window, enter SEDRO WOOLLEY.
5. Click on the SEARCH button. The resulting list includes 16 entries of various newspapers which were published in Sedro Woolley or may have been that city’s newspaper of records (printer of official notices) in various time frames.
6. Notice that the newspaper THE SKAGIT COUNTY COURIER (item 10) is shown as published in 1900-1918. Click on the newspaper’s name.
7. The page for The Skagit County Courier shows this newspaper is (FREQUENCY) a weekly; (PUBLISHED) began publishing in 1900, but it also says (NOTES) that the Description is based on: Vol. 3, no. 1 (May 14, 1903). We can assume the earliest issues are not available.
8. Above these entries, the LOCATION column shows the only microfilm of this newspaper is located in the Washington State Library Microfilm Newspapers collection. The CALL # column lists NEWSPAPER 9/A and the available issues run 1903 MAY 14 - 1905 MAY 4; and 1918 FEB 7 - DEC 26. (Major gap.)
9. In the space above this line, click on NEWSPAPER PUBLISHING HISTORY CHART. Looking through this history (or descendancy) chart, note that the SKAGIT COUNTY TIMES (published in Sedro-Woolley) was published 1891-1920. Click on that block of the chart.
10. Now, on the Skagit County Times page, in the CALL # column, the first entry you will find is NEWSPAPER 9/A and the time frame 1899 JAN 26 - 1904 APR 28. It appears all issues are included in the time frame you need.
11. Make a copy of that page, take it to your local library and ask them to do an Inter-Library Loan of that microfilm from the Washington State Library. These films can be made available within one week and may only cost you a small amount for postage (depending on your library’s policy).
