Two Dominican blogs have come to my attention in the recent past. Both are American and are worth a visit. For convenience, I will add them to my blog list.
The first blog (http://laydominicans.blogspot.com/) is that of a group of Lay Dominicans in the USA. It is a good resource particularly for information on the saints and blesseds of the Dominican Order and it boasts an excellent link-list.
The second blog (http://dominicancooperatorbrother.blogspot.com/) is one that I highlighted a long time ago. It is the blog of Br Paul Byrd OP, a Dominican brother of the Central Province in the USA. The blog gives an excellent account of the vocation of the Dominican brother and I recommend it highly.
