idea lab Card:

The MCLS idea lab program connects people with learning opportunities, using technology. Want to learn how to edit your photos? Make robots? Practice using a sewing machine? Sell something online? Take a selfie … on purpose! Record a hologram?

The idea lab gives our community the chance to do any of these things – and more! – simply by having a library card. Most idea lab equipment is available on a first come, first served basis. Some equipment is available to take home, too!

To upgrade your library card to an idea lab card, you must sign the idea lab borrowing agreement (English | Español) and have a Martin County library card in good standing. The use of some equipment (eg, a sewing machine) also requires signing a liability waiver. See your local library staff to upgrade your Martin County library card today!

Educator Card:

MCLS offers a special card exclusively to educators. Apply online via this webpage or visit any library branch to sign up for Educator Card. Institutional identification required.

SEFLIN One Card: 

Requires registration at a participating Southeast Florida Library Information Network (SEFLIN) library including the Palm Beach County Library System and Florida Atlantic University.

A lost or stolen library card should be reported in order for the Library to deactivate the card. You may visit or call your local branch to report the card lost or stolen.
