I am accredited Senior Appraiser for Books and Manuscripts, American Society of Appraisers.

I have been in the used/antiquarian book business since 1977, and have done numerous appraisals. I have attended the Columbia University school for librarians who curate rare book collections.  I also attended the AB Bookmans Rare Book School at Denver State College.  I have taken courses in appraisal procedure and USPAP - (Uniform  Standards of Professional Appraisal Practice) from the Appraisal Institute.  I have taken and passed the intensive series of courses on the Principles of Evaluation offered by the American Society of Appraisers. I have taught graduate level courses at Portland State University on the book business, bookselling and related to developmental editing since 2001. 

I have bought and sold books on a regular basis since the mid-1960's when I started my career as a teenage book-scout. I was an assistant manager at Powell's Bookstore in downtown Portland, Oregon, when the assistant manager answered only to the store owner.  I created the new books division and was the first buyer for Powell's.  I was also responsible for establishing the used book department as well as the rare books department.  I also contributed to the creation of the "Price Task Force," which is the division responsible for pricing many of the used books that come into Powell's.  

I was the manager at the Great Northwest Bookstore, also in Portland, Oregon.  I was responsible for purchasing, pricing and selling used books, rare books, unusual and desirable pamphlets, printed sheets (the pamphlets and sheets are often referred to as "ephemera.")    I wrote and issued catalogues for 19 years. I specialize in the appraisal of  archives.  Personal archives usually contain personal letters, diaries, scrapbooks, photographs, and an assortment of printed or handwritten papers.  Professional archives may well include all of the preceding, but may also contain technical papers, studies, notes, research, and perhaps drawings.
