he Forest Products Laboratory (FPL) in Madison, WI is an institution of 200+ research scientists all focused on what you can do with wood and wood fibers. It was a unique research agency when it was founded in 1910, and remains so today. Over it's long history, it has published thousands of valuable studies on wood, plywood, sheet materials, wood products, adhesives, glues, fasteners, finishes, and all things to do with wood. However, the Wood Handbook is arguably the FPL's most useful and important contribution to woodworking. It's become an indispensable reference work for millions of woodworkers world-wide.
Part of the campus of the Forest Product Laboratories at the University of Wisconsin in Madison, WI. The FPL is part of the Forest Service, Department of Agriculture.

As important as it is, not all parts of the Wood Handbook are useful to all woodworkers. Depending on your interests, you may find yourself referring to some parts of it more often than others. For that reason, we've broken it down into chapters so that you can access or download just those parts that interest you. However, if you'd like to refer to the entire work, click HERE.

The files are in PDF format, so you must have Acrobat Reader™ or some other PDF reader installed to view them. If you just want to view the information,  click on the links. To download these files, right-click on the links and choose "Save Target As" from the menu that appears.

If you're viewing this page in IE (Internet Explorer), the Wood Handbook Table of Contents is expandable. If there is an arrow () in front of a chapter title, this indicates that there are subtitles for chapter sections. Click on the arrow, and the contents will expand, revealing the hidden subtitles.
