This site is dedicated to presentation of books written by exceptional British physicist Harold Aspden.
Harold Aspden's older books are available only as PDF made by scanning, each chapter in separate document. This format cannot be used very well in modern reading devices, therefore I decided to convert these PDF books into HTML and to eBook formats, in order to make them more accessible by those who would wish to study them.
All books presented here are copyright of Harold Aspden and are published under Creative Commons Licence.
I would like to thank Mrs. Wendy Aspden for her permission to convert the books and for her kind support of this activity, and to Mr. Giuseppe Filotto for help and support.
