The history of travel, travelers, and travel writing is an academic discipline in it's own right. Travelers accounts of journeys from before Pausanius to the present form an important corpus of descriptive documentation of ancient monuments and sites, many of them no longer visible. ASTENE: The Association for the Study of Travel in Egypt and the Near East organizes conferences and publishes a Bulletin devoted to the topic. The venerable Hakluyt Society has been the focus of publication of scholarly editions of primary records of voyages, travels and other geographical material since 1846. Shirley Weber's compendious bibliography Voyages and travels in Greece, the Near East, and adjacent regions, made previous to the year 1801; being a part of a larger catalogue of works on geography, cartography, voyages and travels, in the Gennadius Library in Athens has been available online for some time (though) it has been brought to my attention that it in no longer open access).
The discipline seems to be an attractive one for the development of open access digital libraries.
- American Travelers in Italy is a collected and curated at the Harold B. Lee Library, Brighsam Young University.
- Early Explorers in Egypt & Nubia. Daniele Salvoldi's blog collects a wide variety of useful documentation, in particular those tagged as On-Line resources.

- Travel Literature on Southeast Europe and the Eastern Mediterranean 15th-19th centuries. This is a component of PANDEKTIS - A Digital Thesaurus of Primary Sources for Greek History and Culture, produced by the National Hellenic Research Foundation, Athens. It includes descriptive metadata on more than three thousand items, many of which include digitized facsimiles.
- Travels in Southeastern Europe. This collection is a component of the University of Michigan's Digital Library Collections and Publications. It includes 137 items, mostly scanned volumes, with a focus on Bosnia and Hercegovina. Many of the volumes include travel to other parts of the Mediterranean and Near East during the period of the Ottoman Empire.

I encourage readers here to let me know by means of the comments or otherwise, of other useful open access collections.
