The Directory of Museums in India has been prepared with the objective of collecting at one place all the basic information on museums, the type of information normally required by any prospective visitor/tourist. For each museum in the country, it gives full address, telephone numbers, opening and closing time, closed days, entrance fee, the types of collections the museum has, and so on. It also mentions about the publications of each museum, whether a library is available or not, and whether photography is permitted. It also gives valuable information on the availability of guide services or holding of lectures or film shows. At the end, as guide to the visitor, the type of museums, whether it is archaeological, ethnological, art museum, or science museum, etc. is also indicated. All in all it is a compendium of infor-mation commonly sought by any person who wants to visit a museum. The first edition of the Directory of Museums in India was published in the year 2000. This is the 4th edition. In this edition many new museums has been added. Some museums which existed once upon a time but not now, have been deleted. More information on each museum has been given, what changes have taken place in any particular museum have also been added. This is the only book of its type on Indian museums where all the relevant data useful for visitors, tourists, museum persons, scholars, libraries and planners is available.
