My 4 Old Books (gnv64) torrent

In this torrent, I am sharing 4 old books published almost 50 years back. They are out of print by now. Actually, they belong to my father & are not in good shape. I decided to convert them to ebooks so that they can be preserved longer & shared. All are in PDF format with OCR, bookmarks, covers & internal links from the TOC:

1. Advances of Modern Science by Melvin Berger
Pyramid Books | 1964 | 125 pages | 3.19 mb
2. Life on Other Worlds by H. Spencer Jones
Mentor Books | 1954 | 160 pages | 5.89 mb
3. Man, The Unknown by Dr. Alexis Carrell
Wilco Publishing House | 1959 | 234 pages | 7.43 mb
4. Scientists Behind the Inventors by Roger Burlingame
Avon Books | 1960 | 128 pages | 4.53 mb
