For the past several years, almost all newly published items added to the library’s collection have been in electronic format only. These items are accessible in full text through the library’s intranet catalog. Many old print materials have also been digitized and uploaded to the library’s catalog.
To get a general sense of a subject’s history, however, you may find it useful to browse the library stacks in certain locations to see print copies of older publications (and the occasional newer item that was published both electronically and in print). For publications related to transportation, call number ranges include, but are not limited to:
380 commerce, communications and transportation
385 railroad transportation
386 inland waterway and ferry transportation
387 water, air and space transportation
388 transportation; ground transportation
Hard copies of mandated reports that were produced only once or as a limited series are shelved by the number of the act that required the report. Hard copies of mandated reports produced regularly with no set end date (for example, state agencies’ annual reports) are shelved in the stacks by subject.
