      Perma was started by Doubleday in 1949 during the heyday of 
      paperbacks, just in time for the “paperback glut” of the early 50’s. The 
      concept was to roll Doubleday’s hardcover offerings right into paperback 
      circulation when it deemed the works ready.  
      There were many radical experiments in the major paperback 
      houses during this period. Most were abject failures, financially, 
      including Dell’s l0˘ series of books. Perma’s addition to 
      this Hall of Failures was a series of “Hardcover Paperbacks,” that is, 
      hardcover versions of paperback-size books. They sold for 35˘, and most 
      were non-fiction. Some were used as supplemental texts in schools.  
      These were the first "P" series Perma books. 
      Rather than watching Perma continue to fail financially, 
      Doubleday sold the entire paperback operation to Pocket Book in 1954. They 
      ran a pretty profitable program into the 60’s and beyond. 
      So there are several “series” of books in the 
      database. The first offerings were the 35˘ “P” series, which included both 
      the hardcover books and "double-sized"  paperbacks (meaning 
      they were about twice as thick). There were also some 25˘ non-lettered books 
      called “Perma Stars,” interspersed in numerical order.  
      After Pocket Book took over, they changed to “M” series 
      books, using 3000 (25˘) and 4000 (35˘) numbering. As the decade 
      progressed, the Perma Books looked more and more like Pocket Books and 
      Cardinals, with the distinctive silver or gold spines.                 The Perma Database was
