I highly recommend if you love these little creatures and want to identify most species that you come across every day-at least the kind with more or less certainty.
Just for those who did not want to put as much money in a book, the book "What is this spider?" is the same as the pictures are of the same author and the introduction of anatomy such schemes are identical -although of course it is much less in cash and provided details but it is really good for a small budget.
