It is believed by some people that libraries should aim to provide traditional books to the public, while provisions of electronic data such as computer software, videos, and DVDs are wastes for libraries whose resources and space are limited. I totally disagree with their opinion.
For one, as one of the public services that serve information to civilians, libraries undertake the responsibility to provide comprehensive information via different mediums, yet only providing traditional books is deficient. In the public library that only supplies paper books to citizens, especially for those citizens who are illiterate or blind, hardly do they read books. In this case, such electronic devices would be the choice via supplying some documentaries, audiobooks, and DVDs, which enable every individual to acquire information by hearing or watching without biological barriers.
For another, in considering the efficiency in exerting the limiting resources in public libraries, supplying new forms of mediums would be served as thrifts rather than wastes of space and resources. Since one electronic book is able to contain the content of hundreds of books written on paper, each provision of an electronic book equals to preserve substantial paper books. Had it not been for supplying paper books, there are considerable expenditures on maintenance which could be originally allocated to other programs such as to purchase new devices.
In conclusion, based on facts, public libraries should not only serve information in electronic form, but also guarantee that the provision of those devices is sufficient. Introduction of electronic mediums generates and boosts the productivity of libraries, and contributes to the public who require to find information with plentiful and various methods.
