Here the market divides1. Traditional ILS vendors
•Terms:•“legacy”•“proprietary”
•Two types:•Founders still around•Founders have sold out to VCs
![Page 7: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/7.jpg)
1. Traditional Vendors (continued)
Characteristics:•Compiled code (machine readable code)•Intellectual property laws apply•They own the code and you rent it.
•Advantages•“turn key”•comprehensive solution to many problems•documentation and support
![Page 8: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/8.jpg)
1. Traditional Vendors (continued)
Disadvantages•Slow development cycle•One size may not fit all•Who owns your data?•Restrictive licenses•Forced migrations•vendor lockin

2. Open source

![Page 11: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/11.jpg)
What does “open source” mean?
“A set of principles and practices about how to write software the most important of which is that the source code is openly available....”[additionally] “...one should have the right to use it.”
Wikipedia, “Open source”
![Page 12: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/12.jpg)
What does “source code” mean?“human readable”
What does “compiled code” mean?machine readable
![Page 13: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/13.jpg)
Advantages of the open source method Easy customization for your own local situation Fast development - “release early, release often” Cost—it's free. can have about the same support as proprietary software
![Page 14: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/14.jpg)
Disadvantages of open source
•It's free but it may not be cheap•Support—if you can't, who supports it?
![Page 15: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/15.jpg)
What happens if your ILS won't do something you need?
Proprietary•Wait until the next version
Open source•Do it yourself (or with others in the community)•Either pay someone yourself or get others to contribute •Cajole, persuade, or charm someone into doing it

State of the OSS US public library marketabout 1-2% ,give or take
no figures for the academic market but they are assuredly lower
![Page 17: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/17.jpg)
But there is a new wind blowing:• Evergreen
• Indiana Open Source ILS Initiative• Sitka• Michigan Library Consortium
• Koha• MassCat• INCOLSA• WALDO
![Page 18: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/18.jpg)
OSS opens the way for us to change libraries and their interaction with our users
Evergreen offers one way
![Page 19: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/19.jpg)
ILSs reflect their beginningsEvergreen started on PINES
Large, resource-sharing consortium with a single catalog
Universal borrower card
![Page 20: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/20.jpg)
What have we learned from the PINES experience?
• Library users LIKE access to the large virtual library
• They don't care about our politics or the difficulties under the hood
• They will bypass libraries without access to consortial resources in favor of libraries with that access
• Welcome to the long-tail, Google world
![Page 21: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/21.jpg)
Silos Separate, barely communicating collections of information
Logic of IT is to break down silos and to integrate these collections
We have these persistent silos for three reasons:Legacy vendor's lack of visionOur lack of vision and/or politics
Think locally, act locallyUntil now, no software to run these large consortia

Evergreen design parameters
•Had to handle PINES•40+ PL systems, 250+ outlets•14+ million circs•on a statewide resource-sharing network•and scale up from there
![Page 25: Open source and ILSs Bob Molyneux Rowan Public Library Salisbury, North Carolina July 30, 2009](https://reader036.vdocuments.us/reader036/viewer/2022062411/5681564e550346895dc3eed1/html5/thumbnails/25.jpg)
Architecture
Open Service Resource Format (OpenSRF)Service oriented architecture
Modern, modular, scalable
The only ILS software that can currently run large and distributed resource-sharing networks.

FullfILLment (tm)
• Attempt to get past the silos to one dynamic, real time search mechanism
• Evergreen backend, with opportunistic connectors to legacy vendor software

What other futures are possible in an open source world?
Modular—not one size fits all•More open source choices, perhaps more specialized
•Index Data•VU Find•Blacklight
Mix and match•Why not open source and proprietary?•Code sharing
