Archaeologists recently uncovered the remains of a public library in Cologne, Germany, which they surmise was built in the second century of the common era by the Romans or the workers of the Roman client state in control of the region. The architecture follows the model of other large Roman libraries of the period, such as the one in Ephesus, on the western coast of modern Turkey. The reason for thinking it was a public library rather than a private one is the great size of the structure and its location in the public forum of the ancient city, where all buildings were public.

The meaning of “public” was also limited at that time to those who were literate and therefore had a reason to be there accessing the books. These would have been scholars of one sort or another, whether in the employ of government, academia, or a wealthy individual, and they would have been almost certainly all male. Lending libraries did not come about until the Renaissance, after the invention of the printing press made available large numbers of copies of books at lower cost.

The model caught on, obviously, since today there are over 16,000 public libraries around the country. In the past 30 years or more, two great changes have affected those public libraries, and they are no longer what they were during their heyday in the twentieth century. The first change came from the effects of cutbacks in social programs starting with the Reagan administration. Homeless numbers increased as politicians undercut the social safety net and as mental hospitals could no longer afford to house indigent patients, setting them loose on the streets. Shelters that took in homeless people overnight often turned them out during the day, and the homeless gravitated toward public libraries for safe daytime shelter with access to bathrooms.

With the influx of people who are not readers as much as internet users and are likely as not indifferent to norms of behavior in the library, and homeless people who sometimes abuse library facilities and even other patrons, librarians now have their hands full with duties that have nothing to do with their traditional training in library science. Patrons who are readers and have used their local library’s services in person for decades no longer feel comfortable there, and now often prefer checking out electronic books from the library’s website rather than visiting the library in person. Pity the unfortunate librarians then, who cannot escape the loud cell phone users, the raucous children who have been dumped by their parents in the young readers’ room as if it were a free day care center, and the homeless people who, often through no fault of their own, have been thrown on the good graces of the librarians, but who complicate the work day for those overburdened librarians by the criminal or mentally unstable acting out of some of their number.
