Some scumbag(s) have robbed a few days ago a very valuable library in Monsey, New York. The owner is currently sick in the hospital, the thieves took their chance, when the family of the sick man were visiting him and looted the library. If you are offered a collection of rare Kabbalistic and Hasidic books, be sure you are not buying stolen books.
It is very sad that in such a business, that of selling holy books, we need to be worried of such things. But a certain breed of people have proven time and again, that this business has it's giant share of thieves, forgers, scammers and their cronies. It appears the evil inclination does not discriminate between one business and another.
