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 AV Equipment or group study resources.

How does checkout work?

You can check items in/out in the admin portal, or allow self-checkout. “Simple Circulation” mode is perfect for high-trust environments, like congregations, where all users share one common password. “Full Circulation” mode gives your community members individual accounts and logins.

Do we need library cards?

You don’t need to use library cards for your members, but we do offer full barcode support if you have them. You can also create your own library cards by exporting your user data and running a simple mail merge.

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.

How many users can I have?

As many as you need: there’s no limit to the number of users you can add or import to your TinyCat.

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 faith community use TinyCat, and TinyCat manages your circulation and member data. Cataloging—including copy-cataloging, importing MARC records and editing records—is always done on LibraryThing.

Powered by LibraryThing

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

Started in 2016, TinyCat transforms your collection in LibraryThing into a simple and attractive small library catalog. With over 4,900 sources for cataloging information, LibraryThing is a wealth of data for and about your library. TinyCat allows you to share that with your congregation.
