Going to the library ain’t easy. Or rather, it is very difficult. Firstly, you got to go there physically fighting out all the hurdles of commuting, weather, health, time and many others. To add to it you have to move along with your entire Jing bang of laptop, notes, books so that the time you spent there actually becomes productive. Hours spent in the library on daily basis can actually get depressing and may even challenge the smile of the most optimistic and cheerful of persons. For decades all together, this has been the only alternative with researchers and however mundane the task be, they have had to be doing this to be able to do their research. Blessed are those who are researchers of today’s time. They needn’t physically move out to the library for research. Rather the library has come to their door step. Google books give access to a whole lot of books online. It is simple easy and free. I suppose, it does not give access to the most latest of stuff, but for a dissertation sufficient content can be extracted from the net. Sometimes, Google Books does not give access to full books but eve getting to read few pages can help to solve the purpose you need to derive from the book.
I wonder, how many of the new scholars would understand the benefit of this wonderful advantage of Google Books which allows you to search for this specific content within the book so you need not hunt the entire book looking for a particular paragraph. Google does that for you and helps you to save your time and energy for other mundane tasks associated with PhD.
The present generation researchers, in my opinion should be indebted to technology, specifically Google for giving the simple techniques through which they can decorate their thesis with relevant citations without having to face the ordeal of visiting a library day after day.
