El Dorado County is sort of a process to find the book and page.  Here is what I find easiest.  Follow the link below to the El Dorado County Assessor.  Then search your parcel on the left (light blue box).  After clicking search (magnifying glass) a few boxes will appear on the right.  Click “Historical Property Details”.  A page will come up, click on the upper right hyperlink titled “Assessor’s Plat XXX-XX”.  It will download the plat map (or some counties call this plat the assessor parcel map).  On most plats, the Book and Page relating to the plat will be listed on that plat.  I have included a link to an example plat where I show you this information.  See link below.
