As of yesterday, I have found it impossible to access books and periodicals
digitalized by Google.  For example, searching for a specific date of
Billboard, Dec 6, 1952, when I click on the url,

https://books.google.com/books?id=CSAEAAAAMBAJ&pg=PA26&lpg=PA26&dq=billboard+dec+6+1952&source=bl&ots=o9gFa3Qy13&sig=Y8ex6IvnlrJAxeVMG3M6D99zXes&hl=en&sa=X&ved=0ahUKEwifmNe_m8HJAhXHez4KHc45AbMQ6AEIHDAA#v=onepage&q=billboard%20dec%206%201952&f=false

the entry does not appear.  I get only a blank screen.

Is this infinitely useful resource no longer available, or is this just a
temporary glitch?
