Recommended Formats Statement

1. Uncompiled Source Code: A file-based copy of the source code from which the software was developed. Metadata that specifies which compiler was used to create the final code for commercial release—including the version number and build number of the compiler software—must be included. If the compiler is unique to the project or company (i.e. not commercially available), then a copy of compiler software in the specific version and build used to create this version of the software, along with specifications of the platform the compiler ran on, must be included in the submission. This submission should include the rights clearance for the Library to install and use the compiler to read and use the provided information.
2. Gold master build (specific file types will vary depending on company producing build)
3. Distribution file (e.g. ipa [Mac iOS], apk [Android], exe [Windows])
4. Disk-based physical release of game/software content

Hard drive/flash drive/writable disk of game/software content

Operating system: If not a commonly available OS, then a copy of the OS, submitted as a disk image, must be provided with the submission. 

NOTE: If there are different versions released at the same time for different operating systems (e.g. for Mac, Windows and Xbox One), a submission will be required for each.

If a submission requires a stand-alone or proprietary platform (e.g. a gaming system or child’s toy), then a virtual or emulated version of the proprietary platform is required with submission.

If a submission requires a stand-alone or proprietary platform (e.g. a gaming system or child’s toy), and a virtual or emulated version of the proprietary platform is not available, a physical platform including controllers and power supply is acceptable.

With documentation and other accompanying material (e.g. instruction materials, errata, addenda, read me files). A copy of the electronic distribution file if the product was sold to the public as a downloadable file. Note: if the software was a part of a book publication (e.g. a software manual with accompanying discs), then a copy of the book must be submitted with the disc.

Direct File Submission: These submissions would require grouping in a submission package such as BagIt, Tape Archive (tar), or AXF object.

Submissions of uncompiled source code must include the rights clearance for the Library to install and use the compiler to read and use the provided information.

Files must contain no measures (such as digital rights management technologies or encryption) that control access to or prevent use of the digital work.)

A file containing digital rights management technologies or encryption which requires a stand-alone or proprietary platform is accompanied by a virtual or emulated version of the proprietary platform or a physical version of the platform.

However, the file cannot include a connection to a remote server for DRM or encryption services.
