SirsiDynix Symphony® provides a proven core for the next generation in library technology: the BLUEcloud Suite LSP. BLUEcloud gives you web clients available on any device and adds depth and breadth to Symphony's bank of over 600 APIs and web services. Powerful BLUEcloud products such as AnalyticsBLUEcloud Cataloging, and eRC take advantage of Symphony's secure back end to bring you practical insights, fluid workflows, and end-to-end native eResource management. 

Libraries today are not a one-size-fits-all breed. At SirsiDynix, we feel great responsibility to each individual library we serve and, thus, refuse to create one-size-fits all technology. The SirsiDynix Symphony ILS is the cornerstone of this commitment. With the Symphony system, your library can benefit from intuitive, robust technology with all the bells and whistles, a rich patron interface, and a fully adaptable, expandable and customizable platform. It can be as complex or as simple as you need it to be today; but if your needs change tomorrow, it’s ready for the challenge.

572 APIs
and more than 150 web services make Symphony as flexible as possible.
BLUEcloud Campus

Take advantage of fully developed traditional capabilities along with exciting new ways to handle your extensive electronic holdings, collaboration with other institutions and third parties, and all of your digital resources. From open data to SOA, BLUEcloud Campus lets you take two steps forward without sacrificing a step along the way.


For library staff, security is a vital priority. Symphony gives you extreme control over viewing privileges, policies and more. And for your system, Symphony's built-in offline mode kicks in to handle those pesky power and network outages.


Flexible circulation policies put you in control of what goes where, and when, and how. And with fully documented APIs and an open development platform for tweaking the system at will, you might just get a power trip.


More than any other system, Symphony lets libraries serve their users. Books by mail, self-service holds, mobile circulation support and more ensure that however your users access the library, your system is agile and available to support them.


Demand management for efficient fulfillment of popular materials; blanket holds across multiple titles or items; batch editing and on-shelf hold processing; right-click menus; and group management tools for families or book groups are only a few of Symphony's streamlining strengths.


Flexible policies control display and access to all types of records and demand management make Symphony the best platform for holds/request management.
