Primary sources – literature
Thesaurus Linguae Graecae (TGL):
Full text database of virtually all ancient Greek texts surviving from the period between Homer (8th century BC) and AD 600. Available as an electronic resource via Robinson.
Perseus Digital Library:
http://www.perseus.tufts.edu/hopper
Excellent starting point for all things Greek and for many things Roman. An extensive collection of images and of Greek and Latin texts, translations, essays and many other useful tools for studying ancient Greek and Latin language, literature, and culture.
Bibliotheca Teubneriana
Latin text equivalent of the above, but Robinson does not have this series electronically – look up the texts by author and consult the relevant volume in the library. Note that www.thelatinlibrary.com has most of Latin literature in the original if you want to find an online version quickly.
Primary sources – epigraphy (inscriptions)
The key resources here are Corpus Inscriptionum Graecarum (CIG), Inscriptiones Graecae (IG) and Corpus Inscriptionum Latinarum (CIL), some of the multiple volumes of which can be found in Robinson. It is often much easier to use the online resources below than to navigate the complexities of the CIG/IG/CIL paper volumes, which are not written in English. Better still, some of these online resources are searchable not only by the relevant CIL/IG/CIL number (helping you to locate specific inscriptions) but also by keyword, so you can also find new inscriptions you don’t yet know about.
Any inscription in CIL is identified by two numbers, volume and id (e.g.: CIL VI 1188).
An online version of CIL (with images of each inscription) can be found at:

For Britain, the key source is RIB (Roman Inscriptions of Britain), the various fascicules (sub-volumes) of which are available in Robinson. For an online version of RIB Volume 1 (Inscriptions on Stone) see http://www.roman-britain.org/epigraphy/rib_index.htm. RIB 1 contains inscriptions on stone found before 1954 – for those found subsequently see RIB Volume 3, published in 2009. There are also numerous fascicules covering inscriptions made on other types of surface (metal, tesserae, etc).
Information on any British inscription prefixed by RIB (eg RIB 2027) can be located by consulting the relevant RIB volume.
