It almost becomes a de-facto standard to refer everything on-line for those spending 10+ hrs in the digital world, out of which most is spend on reading e-pages. Then reverting back to cellulose page is like switch from e-mail to snail mail but cellulose book is pretty conspicuous no matter how far you are using computer.

After getting started (again) with cellulose page. one thing that need to be decided and is completely depended on readers aptitude is the reference book (of-course on subject varying from programming language, design, packaging etc). It is a book comprising of almost all what one needs and a 500+ page book which acts as an indexer based on which other books can be referred. An eg. is book comprising of
prg lang with code + prg lang with design + code snippets for design + other tools that can be used with it + testing etc. It is like searching needle in an ocean(know that it's suppose to be haystack). For this to happen one has to nearly checkout n books online/offline. *** The experts advise doesn't suit your requirement.

This ref book will always keep changing based on what one wants to know and how much?
