Oort and the Universe: A Sketch of Oort’s Research and Person

I am not a professional astrophysicist so I am NOT really qualified to rate this book, but amazon won't let anyone get away without offering a rating, so I picked 3 stars as an attempt at neutrality.This book contains a series of sophisticated professional astrophysics papers, and almost nothing of interest to nonprofessionals.I have a phd in physics, and still found the book essentially inaccessible.I was hoping to glean something about the Oort Lindblad calculation of the sun's position of the Milky Way. But I was quite disappointed as almost all the material here is too advanced.Perhaps the only thing worthwhile is a reference they give to another book... Galactic Structure (Stars & Stellar Systems) which I hope may be more readable...
