Larson spent many years working out details for an expanded edition of his first publication, The Structure of the Physical Universe. Much of his research ended up in the 3-volume set, Nothing But Motion, Basic Properties of Matter and Universe of Motion, but not everything...

Now available for the first time is the collection of papers that Larson was working on for his expanded edition of the Structure of the Physical Universe, over 300 pages of text, tables, figures, including his hand-written notes and corrections.

Note that this was a work in progress, so there are chapters missing (or perhaps in the process of being renumbered, as there are several chapters with the same number). It is not complete; there are also some pages missing, and the search for them continues.

The Expanded Edition of the Structure of the Physical Universe, 332 pages, coil bound, $35.00

(Note that this is not a "real" book, but a collection of papers and notes. I have added page numbers and an index, as an aid to locating chapters.)
