Open any WT publication (other than tracts) and you will not find (to my knowledge) an ISBN number.

Does anyone know why they would not apply for ISBN numbers?

What is an ISBN?
The ISBN (International Standard Book Number) is a unique machine-readable identification number, which marks any book unmistakably. This number is defined in ISO Standard 2108. The number has been in use now for 30 years and has revolutionised the international book-trade. 166 countries and territories are officially ISBN members. The ISBN accompanies a publication from its production onwards.
The number consists of ten digits:
- Group identifier
- Publisher identifier
- Title identifier

From Wikipedia, the free encyclopedia.
Jump to: navigation, searchThe International Standard Book Number, or ISBN (sometimes pronounced "is-ben"), is a unique [1] identifier for books, intended to be used commercially. The ISBN system was created in the United Kingdom in 1966 by the booksellers and stationers W H Smith and originally called Standard Book Numbering or SBN. It was adopted as international standard ISO 2108 in 1970. A similar identifier, the International Standard Serial Number (ISSN), is used for periodical publications such as magazines.
Although the WTS books are available on a donation basis, when they were being "sold" why wasn't an ISBN number procured, so the books could be sold in shops etc?
