Q. Community use

Unfortunately, our policy does not allow anyone under the age of 16 to be in our computer lab. This means your students could not access most library resources, including databases and the bulk of eBook collection. Even the internet would be off limits.

I'm guessing a public library will be your best bet. They won't have restrictions like many academic libraries do.

I've included links to  a list of public libraries in Galveston County, in case La Marque isn't a good choice for you, for whatever reason.

I do hope this helps.
