Nine Years

Nine years ago I started this blog.  After learning how simple it was, I decided to create a blog that could keep custodians and other interested readers informed about things that custodians deal with and news that pertains to the custodial field.  To date, I've posted almost 550 entries covering subjects about other custodians, interesting news items, personal comments, useful information and more.  I enjoy sharing this information and will forge ahead for another year sharing items regarding the custodial world.
