Print and non-print media co-exists every where in all types of libraries.
Based on the factors like - Information needs of the users, IT infrastructure available, cost of the information resource, purchase options available (only print or only non-print - no option available), library automation, library professionals available to manage the resources -- one can select print or non-print.
In my opinion, our society will not be paper less even if lots of print is converted to e-format.
We are surely already making a journey towards a paperless society..hence most professionals and businessmen use electronic-storage devices like pendrive and carry laptops only to meetings and conferences..nowadays e-mail is also serving as an effective means of information storage and retrieval ..ther is no more need to carry every piece of information or any important document in print form only..you can have an electronic/digital form of it and take printout anytime needed..so paper has become less impotant than before.
Microsoft researcher Bill Hill has predicted that with the invention of ClearType and eBook technology, eBooks will become widespread within the next 2-1/2 years and commonplace within the next half decade. Ultimately, he says, the shift from paper to the computer screen will spur a transformation equal in magnitude to the printing press. "The next five to 10 years will probably change society as much as the 200 or 300 years that happened after Gutenberg," Hill says. "It's not going to happen overnight, it's not going to happen tomorrow, but it's going to happen very quickly. We're on the verge of something."
