What qualifies as a "volunteer library"?

To qualify as a "volunteer library" the library must have no paid library staff and no regular acquisitions budget exceeding $500.

General institutional staff, such as maintenance, or a rabbi or minister, who do not manage the church's library, are not considered library staff.

Special Cases: Classroom libraries are ALWAYS considered volunteer libraries.

What qualifies as a "personal library"?

Personal libraries are for personal use, including families. A shared, non-profit library used by others is not considered personal.

TinyCat is the Best Library Management System For:

  • Schools

    Public schools, private schools and homeschool libraries are able to update class lists easily through TinyCat’s complete patron import-export loop.

  • Classrooms

    Teachers love TinyCat’s easy-to-use interface, including a simple self-checkout system, for their students.

  • Community Groups

    Volunteer-run organizations keep their library management costs low through TinyCat's affordable subscriptions, starting from just $3/month.

  • Health Libraries

    TinyCat helps hospitals and other health industry libraries maintain specific privacy standards for their patrons.

  • Houses of Worship

    Churches, synagogues, mosques and other places of worship make up one of the largest types of libraries using TinyCat. Every member of the community can access the library from home.

  • Museums

    Libraries can catalog non-book materials like historical artifacts through LibraryThing's media support and custom imports.

  • Small Libraries

    If you have a collection of anything under 20,000 items, there's a good chance you can use TinyCat to share and keep track of everything online, including circulation and patron data.

  • Businesses

    Law libraries, training libraries for staff, and reference libraries for customers all currently use the TinyCat system.

Frequently Asked Questions

Who can use TinyCat?

TinyCat was made specially for tiny libraries with up to 20,000 items. Personal LibraryThing members can also use TinyCat.

Is TinyCat just for books?

TinyCat is the library management system for everything you have, from DVDs and CDs to audiobooks and ebooks. You can even catalog specialty items, like board games and electronics.

What are the technical requirements for my library to use TinyCat?

Since TinyCat is web-based, with no software to maintain or update, the technical requirements are simple: a modern web browser and an internet connection.

Do you have support?

You can send us an email anytime, and we have additional discussion forums on LibraryThing.

How are LibraryThing and TinyCat related?

TinyCat turns any public LibraryThing account into a full-featured library OPAC and ILS. Your visitors and patrons use TinyCat, and TinyCat manages your circulation and patron data. Cataloging—including copy-cataloging, importing MARC records and editing records—is always done on LibraryThing.

Is TinyCat done?

No way! We're always working to improve TinyCat and we welcome your feedback and suggestions as we continue to grow.

Powered by LibraryThing

Since 2005, LibraryThing has been the leader in home cataloging, but it’s too big, open, and social for small library patrons.
