Library, Useful to Some and Useless to Others.

Another major moral booster is having a library on ship. On modern naval ships the library is a place to study in quiet, an excellent place for group study sessions for the next advancement exam or a class, and somewhere to pick up a book as a break from someone’s everyday life. Although the stereotypical military person would never willingly read a book, there are always those in every stereotype that break the mold and are rarely seen without a book nearby. Besides, a typical library has lots of reference books that can be used to look up information for classes or just for random facts that have been bugging that person for hours.
Of course, now a days all books are going digital so an actual physical room will likely be redundant in the future (although they may need a special server for all the books throughout history). In the future all anyone may do is download their book onto their electronic reader, such as the modern Kindle or the Sony version, and read it anywhere they want. In the television series Star Trek: Voyager they replicated books by choosing the book to put on the paper and a full book showed up in their replicator. When they finished their book, they just put the book back in the replicator and it was recycled into another book or anything else needed at the moment. There are many ways to handle a library on ship and it is your decision how you want to do it but you never know when it may come up in your writing so it’s best to have at least a basic idea of how it works on your fictional ship.
