If the landlord doesnât give the notice of a rent increase is the right way, the tenant usually doesnât have to pay the increase, and the landlord has to do it over again. The tenant should be careful to pay the old rent.
The International Standard Book Number (ISBN) is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007. The method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country.
A DOI is a digital object identifier, a unique number that is assigned to a digital or electronic work. A DOI that is assigned to a scholarly article basically works the same way an ISBN number works for a print book.
