Even these ancient libraries are now being made available online so that anyone anywhere can gain access to them without any problem. Online libraries have been established which feature hundreds of thousands of books which are now accessible to anyone without any restrictions.

Although they are not entirely free and demand a small membership fee from users but considering the vast amount of knowledge made available by them, this fee seems highly insignificant.

There are several online libraries hosted my many countries of the world and represent a ton of information which was not previously available to man. These libraries not just contain a few encyclopedias but a huge mass of information that is well over millions of books and journals published all over the world.
