Castroville Public Library would not be able to run without our many wonderful volunteers! We have two levels of volunteers: General volunteers and Certified volunteers. General volunteers can help with general library duties, such as straightening shelves, cleaning, and other miscellaneous projects. Certified volunteers must complete a minimum of forty volunteer hours, training, and pass a certification test. If you would like to volunteer your time at the library, please contact us at 830-931-4095. Please provide at least a day's notice before you would like to come in so that we can check our availability. | Find us on Social Media! Connect with us on Facebook & Twitter.
