Bibliographic Resources

General Dictionaries and Encyclopedias of the Ancient World:

The Oxford Classical Dictionary / Off Campus Link, 4th edition. Edited by Simon Hornblower and Antony Spawforth, REF DE5 .O9 2012
Commonly known as the OCD, this one-volume dictionary is the best place to start looking for a topic. Articles are written for the non-specialist and contain a basic bibliography as well as full cross-referencing.  

Der Neue Pauly / Brill’s New Pauly, Ref DE5 .N39 (English edition) / DE5 .N4183 (German edition)
This multi-volume encyclopedia should be your next stop.  DNP/BNP far exceeds the OCD in both the breadth and depth of its coverage. Originally published in German, an English translation is now available. 

Paulys real-encyclopädie der classischen altertumswissenschaft (usually referred to as Pauly-Wissowa or RE), REF DE5 .P33 / List of Volumes with contents
Monumental multi-volume encyclopedia of the ancient world published in German between 1894 and 1978. This is extremely cumbersome to use, both due to its size and the fact that many articles appear in updated or revised forms in the 15 supplementary volumes. Consult Murphy, J. Index to the supplements and suppl. volumes of Pauly-Wissowa's R. E., REF DE5 .P33 sup., Index, 1980b to locate these. A monument to 19th century classical scholarship, many of the articles in Pauly-Wissowa are essentially full monographs instead of encyclopedia entries, and for many figures and events this is still one of the best resources available, especially for its citations of ancient sources, even if it is not the most accessible for undergraduates.

Civilization of the Ancient Mediterranean: Greece and Rome, Ref DE 59 .C55 1988
Unlike the above works, this 3 volume encyclopedia is composed of a small number of broad essays on major topics of the ancient world, including fairly thorough (if now slightly out of date) bibliographies.

Databases and Guides for Scholarship and Bibliography

L’Année philologique / Off Campus Link, Z7016 .M35A
The standard database of classical scholarship. Updated annually, with a lag of about two years. The print version is organized by author and topic, and fully indexed. The online database is somewhat awkward to use, but searches all volumes going back to 1927.  Try keyword searches and jump to the most recent publications.  A list of all abbreviations used can be downloaded here.

TOCS-IN
Searchable, online listing of articles published recently in major scholarly journals.  Not nearly as comprehensive as, but updated more rapidly than, L’Année.

The Bryn Mawr Classical Review
Free scholarly online journal that publishes reviews of recent books on the ancient world and related fields.  Most reviews are in English, although some are in French, Italian or German.  Up to date and fully searchable, the BMCR is a great resource for finding more recent works than those listed in the OCD or DNP or for getting an idea of where the scholarship is heading.  Try doing searches with keywords associated with your topic.

Classical Studies: A Guide to the Reference Literature, by Fred Jenkins. REF PA91 .J4 2006
An in-depth guide to all the encyclopedias, dictionaries, databases, journals, and more relating to the ancient world. Basically, a vastly more detailed and comprehensive version of this page.

Ancient Greece and Rome: A Bibliographic Guide, Ref DE86 .H67 1995
Subdivided by topic, this book provides extensive lists of recent and important works of scholarship.  Focuses mainly on historical, cultural, and related topics.  A quick way to start building your bibliography.

Classical Scholarship: an Annotated Bibliography, Ref DE59 .H35 
Similar to the above, but with a much broader focus on all aspects of the classical world.  Bibliographic entries are annotated, so this gives you some idea of the more specific focuses and trends of scholarly works.

Ancient History: Recent Work and New Directions, 1997 - See me if you wish to consult this, as the library does not own a copy.
This book covers, in four parts, broad trends in research and scholarship in ancient history and the major pieces of scholarship, with a focus on works in English. Slightly out of date, it is very useful for quickly gaining a broad overview of what is out there in the field of ancient history.

Specialized Resources

The Cambridge Ancient History / Off Campus Link, 3rd edition, D57 .C252
Multi-volume history of the ancient world, written by a wide range of leading scholars. The individual volumes focus on specific periods and normally include chapters discussing source problems, narrative history, and other developments.

The Cambridge History of Classical Literature, Volume 1: PA3052 .G73 1985; Volume 2: PA6003 .L3
Two volume overview of classical literature. Volume 1 covers Greek literature and volume 2 covers Latin literature. Volume 1 is very accessible to non-specialists, but Volume 2 is less successful. A far better resource for Latin literature is:
Latin Literature: A History, PA6008 .C6613 1994

Brill's Jacoby / Off Campus Link
Massive, searchable collection of the fragmentary Greek historians, including translations and commentaries. Includes Felix Jacoby's original Die Fragmente der Griechischen Historiker Parts I-III, the updated and revised New Jacoby, and the new continuation of Jacoby's original plans for Parts IV-V (biography, antiquarian literature, geography). This is an ongoing project with much still to be written.

Princeton Encyclopedia of Classical Sites, Ref DE59 .P7
Standard dictionary of major archaeological sites from the classical world. Useful for those working on archaeological topics.

Pictorial Dictionary of Ancient Athens, Ref NA280 .T68 1971
Standard, lavishly illustrated guide to all ancient sites and buildings of Athens.

New Topographical Dictionary of Rome, Fal DG68. R5 1992
Standard dictionary of of the ancient city of Rome, with detailed plans and bibliographies on individual sites and buildings.

Greece & Rome: New Surveys in the Classics. Annually published overviews of recent scholarship and trends in various fields of the Classics. These tend to be more oriented towards literature and culture rather than history, but are still very useful. Some of the most potentially helpful for ancient historians:

The Second Sophistic, B288 .W45 2005
Roman Art, N5760 .S67 2004
