Hello Blitz,first of all,welcome at this forum!
Now,for safe-keeping,the technique varies from persaon to person,plus,from one country to another.I can speak about my way..it's always like these following ways:
1.Proper handling(utmost important if you want the books to last long after several reading).
2.Keeping the book in a proper place like show-case(close) etc and use of naphthalene balls for precaution against termite attack!
3.Binding..allthough not necessary but I have done this many time...but many of my books are single too!
There are several other ways that I heard from other fans...
By the way,from which part(India/other country) you belong??As you have rasied this unique question,may we know your way of keeping??new ideas are welcome!
