Content Curation Policies

All products under contract were thoroughly evaluated by a team of Massachusetts librarians representing a cross-section of school, public, and academic libraries prior to being recommended for purchase. 

Each vendor has their own editorial or content curation process, and questions about specific content within a product should be directed to the vendor. We've collected this information together here for convenience.

Transparent Language

The content featured in Transparent Language Online is tagged for the target audience it’s recommended for. We take a conservative approach to content as it is used by many from different cultures and religious backgrounds, and we want all learners to be able to comfortably use the materials.

When developing something for a specific target audience our content undergoes multiple levels of managerial and quality assurance review in order to make sure that it is appropriate for that audience.

The content itself is written to be likewise interesting and relevant for the young target audience, so they are only learning and being exposed to age-appropriate material. Content developers and reviewers are provided with clear guidelines and specifications for each element of the content. Content targeting adult professionals is likewise carefully reviewed to ensure no content is overly explicit, vulgar, or provocative.
