Why book clubs like it: “When my book group discussed ‘The Nightingale,’ we had all read WWII novels, but this stood out due to its setting in France and its focus on women helping the French Resistance — especially learning how they helped Allied soldiers escape by leading them over the Pyrenees!” said Robin Nyzio, assistant director of the Lincoln Public Library in Lincoln, RI. “Knowing the fictional story was based on real people really did it for us. The setting, the sisters’ relationship, their work with the Resistance along with hiding Jews from the Nazis in an occupied country, all make this a very memorable book.”
Throughout the 20th century, libraries have faced an ever-increasing rate of publishing, sometimes called an information explosion . The advent of electronic publishing and the internet means that much new information is not printed in paper books, but is made available online through a digital library , on CD-ROM , in the form of e-books or other online media. An on-line book is an e-book that is available online through the internet. Though many books are produced digitally, most digital versions are not available to the public, and there is no decline in the rate of paper publishing.  There is an effort, however, to convert books that are in the public domain into a digital medium for unlimited redistribution and infinite availability. This effort is spearheaded by Project Gutenberg combined with Distributed Proofreaders . There have also been new developments in the process of publishing books. Technologies such as POD or " print on demand ", which make it possible to print as few as one book at a time, have made self-publishing (and vanity publishing ) much easier and more affordable. On-demand publishing has allowed publishers, by avoiding the high costs of warehousing, to keep low-selling books in print rather than declaring them out of print.
The reason a comma is put in between the book titles is because, while they are in quotation marks, they are still part of a list. When listing things, you put a comma in between each item. For example, if you were to say “He likes bananas, oranges, and carrots”, you would have to put commas between each item that “He” is said to like. How these commas are placed is a matter of debate for some people, since many are starting to avoid using the Oxford comma. If you do not use the Oxford comma, the sentence would read “He likes bananas, oranges and carrots.”
