Section 508 and Accessibility Compliance
The National Transportation Library (NTL) both links to and collects electronic documents in a variety of formats from a variety of sources. The NTL makes every effort to ensure that the documents it collects are accessible to all persons in accordance with Section 508 of the Rehabilitation Act Amendments of 1998 (29 USC 794d), however, the NTL, as a library and digital repository, collects documents it does not create, and is not responsible for the content or form of documents created by third parties. Since June 21, 2001, all electronic documents developed, procured, maintained or used by the federal government are required to comply with the requirements of Section 508.
Undue Burden Exemption: While the NTL endeavors to make documents fully compliant with Section 508, the cost of conversion of the quantity of documents received would imposing an undue burden in costs rendering the NTL incapable of fulfilling its mission to provide a digital archive. Further, it may not be possible at any expense to make some of the documents fully accessible. Given these restraints, the NTL is committed to using all resources at its disposal to make as much of the collection as possible compliant, and to provide alternative assistance or conversion assistance when requested.
If you encounter problems when accessing our collection, please let us know by writing to librarian@bts.gov or by contacting us at (800) 853-1351. Telephone assistance is available 9AM to 6:30PM Eastern Time, 5 days a week (except Federal holidays). We will attempt to provide the information you need or, if possible, to help you obtain the information in an alternate format. Additionally, the NTL staff can provide assistance by reading documents, facilitate access to specialists with further technical information, and when requested, submit the documents or parts of documents for further conversion.
Document Transcriptions
In an effort to preserve and provide access to older documents, the NTL has chosen to selectively transcribe printed documents into electronic format. This has been achieved by making an OCR (optical character recognition) scan of a printed copy. Transcriptions have been proofed and compared to the originals, but these are NOT exact copies of the official, final documents. Variations in fonts, line spacing, and other typographical elements will differ from the original. All transcribed documents are noted as "Not a True Copy."
The NTL Web site provides access to a graphical representation of certain documents. Thus, if you have any questions or comments regarding our transcription of a document's text, please contact the NTL at librarian@bts.gov. If you have any comment regarding the content of a document, please contact the author and/or the original publisher.
